Conplast constructive solutions ® RMC444M1

Description

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.
