Uses Conplast RMC444M1 is used where a high degree of workability and its retention are required, where delays in transportation or placing are likely or when high ambient temperatures cause rapid slump loss. It facilitate production of high quality concrete. Advantages „ Ready Mixed Concrete- Increased workability and workability retention minimise the risks of long distance deliveries „ Increased strength - Provides high early strength for precast concrete if water reduction is taken advantage of. „ Improved quality - Denser, close textured concrete with reduced porosity and hence more durable. „ Higher cohesion - Risk of segregation and bleeding minimised; thus aids pumping of concrete „ Chloride free - Safe in prestressed concrete and with sulphate resisting cements and marine aggregates. Standards Conplast RMC444M1 complies with IS:9103:1999 and BS:5075 Part 3 and ASTM-C-494 Type 'F' as a high range water reducing admixture and Type G at high dosage. Description Conplast RMC444M1 is supplied as a brown liquid instantly dispersible in water. Conplast RMC444M1 has been specially formulated to give high water reductions upto 25% without loss of workability or to produce high quality concrete of reduced permeability. Properties Specific gravity 1.20 to 1.21 at 300 C Chloride content Nil. to IS:9103-1999and BS:5075 Air entrainment Approx. 1.5% additional air over control Compatibility : Can be used with all types of cements except high alumina cement. Conplast RMC444M1 is compatible with other types of Fosroc admixtures when added separately to the mix. Site trials should be carried out to optimise dosages. Conplast RMC444M1 is suitable for use with all types of OPC and cement replacement materials such as PFA, GGBFS and microsilica. Workability : Can be used to produce flowing concrete that requires no compaction. Some minor adjustments may be required to produce high workable mix without segregation. Cohesion : Cohesion is improved due to dispersion of cement particles thus minimising segregation and improving surface finish. Compressive strength : Conplast RMC444M1 is primarily highly efficient superplasticiser giving large increase in workability without significant change in compressive strength. Conplast RMC444M1 may be used to produce substantial water reduction resulting in a considerable increase in compressive strength. Durability : Reduction in W/C ratio enables increase in density and impermeability thus enhancing durability of concrete. Application instructions Dosage The optimum dosage is best determined by site trials with the concrete mix which enables the effects of workability, strength gain or cement reduction to be measured. Site trials with Conplast RMC444M1 should always be compared with mix containing no admixture. As a guide, the rate of addition is generally in the range of 0.6 - 1.5 litres /100 kg cement. For any deviations in dosage in special applications, please contact Fosroc Technical Services. Overdosing An over dose of double the recommended amount of Conplast RMC444M1, will result in very high workability and some retardation of setting time will occur. However, the ultimate compressive strength will not be impaired. Dispensing The measured quantity of Conplast RMC444M1 should be added along with the gauging water. For best results, add Conplast RMC444M1 in the last phase after prewetting the mix with 80% of the total water required.

Uses „ To improve the effectiveness of the water content of a concrete mix „ At higher dosages to provide cost effective means of reducing concrete permeability and thereby reducing water penetration Advantages „ Allows specified strength grades to be met at reduced cement content or increased workability „ Water reduction significantly improves compressive strength at all ages and enhances durability through the production of low permeability concrete „ Minimises the risk of segregation and bleeding and assists in the production of a dense, close textured surface, improving durability. „ Chloride free, safe for use in prestresses and reinforced concrete „ Allows workability to be increased without adding extra water Standards compliance Conplast P505(T) plasticiser complies with BS 5075 Part 1 and with ASTM C494 as Type B & D. Description Conplast P505(T) plasticiser is a chloride free and water reducing admixture based on selected sugar - reduced lignosulphonate materials. It is supplied as a brown solution which instantly disperses in water. Conplast P505(T) plasticiser disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively and improving the consistency of the concrete. This produces higher levels of workability for the same water content, allowing benefits such as water reduction and increased strengths. Technical support Fosroc provides a technical advisory service for on-site assistance and advice on mix design, admixture selection, evaluation trials and dispensing equipment. Dosage The optimum dosage of Conplast P505(T) plasticiser to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. The normal dosage range is 0.4 to 1.0 litres/100 kg of cementitious material, including PFA, GGBFS or microsilica. Use at other dosages Dosages outside the normal range quoted above can be used to meet particular mix requirements. Contact Fosroc for advice in these cases. Properties Appearance Brown liquid Specific gravity 1.190 - 1.210 at 270 C Chloride content Nil to BS 5075 Air entrainment Typically less than 1% additional air is entrained at normal dosages Instructions for use Compatibility Conplast P505(T) plasticiser is compatible with other Fosroc admixtures used in the same concrete mix. All admixtures should be added to the concrete separately and must not be mixed together prior to addition. The performance of concrete containing more than one admixture should be assessed by trial mixes. Conplast P505(T) plasticiser is suitable for use with all types of ordinary portland cements and cement replacement materials such as PFA, GGBFS and microsilica. Dispensing The correct quantity of Conplast P505(T) plasticiser should be measured by means of a recommended dispenser. The admixture should then be added to the concrete with the mixer water to obtain the best results. Fosroc shall be contacted for advice regarding suitable equipment and its installation. Effects of overdosing An overdose of double the intended amount of Conplast P505(T) plasticiser will result in a significant increase in retardation as compared to that normally obtained at the intended dosage. Provided that adequate curing is maintained, the ultimate strength of the concrete will not be impaired by increased retardation and will generally be increased. The effects of overdosing will be further increased if sulphate resisting cement or cement replacement materials are used. Overdosage may also cause increased air entrainment, which will tend to reduce strength. The degree of this effect will depend on the particular mix design and overdose level.

Uses Conplast MS micro silica is primarily used to improve the properties of hardened concrete where a reduction in permeability, increased durability and resistance to chlorides, sulphates, abrasion, frost attack and alkali silica reaction are required. Advantages „ Significantly reduces permeability by minimising the penetration of moisture and aggressive elements „ Significant reduction in chloride ion penetration by reducing continuous capillary pores „ Improved mechanical properties Description Conplast MS supplied as a fine powder is added to the concrete mix early during the mixing process. The resultant low permeability concrete will exhibit improved mechanical properties, and increased resistance to the effects of chlorides, sulphates, gases, frost attack and alkali silica reaction. Technical Support Fosroc provides a technical advisory service for on-site assistance and advice on admixture selection, evaluation trials and dispensing equipment. Technical data and guidance can be provided for admixtures and other products for use with fresh and hardened concrete. Standards compliance Conforms to ASTM C1240-95a. Dosage Typically 4 to 10% by weight of cement depending upon the specific need. The optimum dosage of Conplast MS to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. Please note higher addition levels are generally required where the high performance concrete such as high strength concrete or underwater concrete is a pre-requisite. Properties Chemical analysis SiO2 Min. 85% Alkalies as Na2 O Max. 1% Loss on ignition Max.5% Bulk density Approx. 610 kg/m3 Application instructions Dispensing and mixing Conplast MS should always be added in the early stages of the mixing process. It is recommended that Conplast MS be weight batched to the required quantity prior to addition to the mix. In dry batching operations, Conplast MS should be dry blended with aggregates and cement prior to the addition of water to the mixer. In wet batching operations Conplast MS should be added to the mixer at the same time as the cement. Conplast MS can if required, be added to the mixer in slurry form. In order to achieve a low water cement ratio, the use of high range water reducing admixtures such as Conplast SP430, Conplast SP423 are highly recommended. Placing When producing concrete with Conplast MS we suggest a target slump in the range of 25 to 35 mm in excess of the normal slump requirement, this will accomodate the additional cohesion promoted by the use of Conplast MS. Concrete produced with Conplast MS will have greatly improved cohesive qualities. Estimating Packaging Conplast MS is available in 15 kg bags.

Uses To improve workability and trowelling properties of sand/ cement mortar mixes during application. To increase quality of masonry and plastering. Advantages „ Improved moisture retention and bond strength: Slows down drying out of mortar which remains workable longer. Ensures better bond to all surfaces, including ceiling. „ Makes mortar crack resistant : Minimises drying shrinkage cracks and increases frost resistance in cold climates. „ High workability : Even with harsh sands, makes creamy easy-to-apply mortar. „ Cost saving : Increase yield of the same quantity of sand/ cement. Extra coverage normally exceeds material costs. „ Better & safer masonry : Mortar fills joints easily and efficiently and ensures stronger construction. „ Improved appearance : Mortar cuts cleanly from faces of brick, block or stone work. „ Increased productivity : Speeds up work by easy application of mortar. Description Cebex 112 is supplied as an off-white to pale yellow liquid which mixes readily with water in any proportions. It is based on internationally recognised chemicals and is free from calcium chloride and similar salts. Technical support Fosroc offers technical support service to specifiers, end users and contractors, as well as on-site technical assistance in locations all over the country. Properties Chloride content : Nil Compatibility with cements : Can be used with any type of Portland, Super Sulphate, Blast furnace or Pozzolanic cements. Setting time : There is no significant effect on the setting of sand/cement mortars. Plasticising action : Cebex 112 entrains a controlled amount of microscopic air bubbles which increase cohesion and provide lubrication to the sane particles in the mix, thereby imparting improved workability to the mortar. The air bubbles hold the cement/water matrix at the contact surfaces which results in improved bond strengths. Frost resistance : Where this is a consideration, that air entrainment appreciably increases the frost resistance of the fully cured mortar and also improves that of fresh mortar, as established by international practice. Increased yield : The special action of Cebex 112 causes the cement particles to disperse evenly throughout the mix, which combined with its air entrainment property, expands the volume of the mortar. Increase in yield for the same quantities of sand and cement is typically between 8% and 18%, depending upon the coarseness or fineness of the sand used. With typical mixes of 1:3 and 1:4 cement : sand, the cost of Cebex 112 will normally be recovered and, in most cases, a net cost saving will be obtained, as a result of the increased yield. Application instructions Mixing Cebex 112 Mortar Plasticiser may be added either direct to an individual mix or to the gauging water, depending upon site convenience. Direct to the mix 1. Use between 0.100 and 0.200 litres of Cebex 112 per 100kgs of cement. Soft fine sand will require least and harsh sands most. Site trials will best determine the practical rate of addition in each case and are recommended. 2. Cebex 112 to be stirred thoroughly before use. Measure the total required quantity of Cebex 112 and stir into the first bucket of the gauging water. 3. After dry mixing the sand/cement in the normal way, add the Cebex 112 and start wet mixing. 4. Continue adding plain water and mixing the mortar until the required workability is obtained. Note : Do not add Cebex 112 directly to dry sand/cement mortar. 1. Add between 0.100 and 0.2 litres of Cebex 112 to every 100 litres of water and stir well to ensure even dispersion.

Use the Cebex 112 to make the mortar in the usual way and keep adding and mixing until the required workability is obtained. Lime Mixes : Where a small quantity of hydrated lime is usually added to a sand/cement mix to fattiness and plasticity, the lime may normally be omitted and Cebex 112 used to replace it with economic benefits. Curing : Mortar containing Cebex 112 should be properly cured in accordance with accepted practice and protected against sun and drying winds. Overdosing : Overdosing of Cebex 112 will result in increased workability and air entrainment. Cleaning : Spillages of Cebex 112 should be removed with water. Limitations Excess dosage of Cebex 112 will result in reduction of the final strength of the mortar. An overdose of double the recommended measure of Conplast P509 will result in increased retardation of the initial set of the concrete. The ultimate strength of the concrete will not be affected and could be increased if advantage is taken of the increased workability by reducing water. Estimating Packaging Cebex 112 is supplied in 100ml, 1, 5, 20 and 200 litre containers. Storage Shelf life Cebex 112 has a minimum shelf life of 12 months under normal ambient temperatures. It should be protected from temperatures above 400 C and stored in shade. Precautions Health and safety instructions Cebex 112 is mildly alkaline. Avoid contact with the skin. Accidental splashes to eyes should be washed immediately with plenty of water and medical treatment sought.
