Description S2-305 is made under the management of competent experts by consuming the finest grade component according to the market norms. S2-305 is plasticising accelerator for cement concrete and mortars Uses: S2-305 is an accelerator suitable for dry as well as wet spray applications. It is used for the following main applications : • S2-305 is of special use in guniting and shot-creting as its accelerated setting times help in quick rebuilding of mortar layers without colla-pse • Rebound losses in shot-creting and guniting are minimized • Early shifting of the pre-cast elements is facilitated • In pre-cast hollow solid blocks, pavers, cement tiles, breaking of the edges while lifting the moulds is minimized • S2-305 helps in early setting of mortars and concrete in low temperature climates Advantages Following arguments specially distinguish S2-305 as catalyser of spraying concrete : • Free from alkali • Good long term strength and durability • In case of proper application, minimum loss of solidity of the catalysed concrete • Reduction of rebound • Improved adhesion of the sprayed concrete on rock and concrete • Improved adhesion in the over head crown portion • Clear reduction of dust and a good working environment • Free from chloride and does not attack reinforcement

SWRR -381 is a highly efficient set retarding concrete admixture. SWRR -381 is used as retarding admixture in concrete where a controlled extention of setting time is required.Use Large volume pours Long haul Avoiding of cold joints Construction joints Difficult placing conditions Elevated temperature Revibrated concrete Ready mix concrete AdvantagesSWRR -381 provides the followings beneficial properties : Increased setting time in hot weather Accelerated hardening after setting Increased ultimate strenghts Long lasting control over slump loss. Better surface finish Chloride free : does not attack reinforcement Improves work ability : Cohesion and extends setting time. Provde protection against delay. Larger pours : Possible with extended placing and compaction times and avoidance of 'cold joint'. Cement savings : Can be obtained by maintaining original strength and work ability. Appearance : Yellowish liquidChemical Base : Poly hydroxyl CompoundPackaging : SWRR-381 is available in 230 kg Non Returnable Drums.Storage & Shelf Life12 months from date of production if stored property in undamaged unopened, original sealed packaging, in dry conditions at temperatures between +10oC and +40oC. Protect from direct sunlight and frost.DosageSWRR-381 0.20-0.6% by weight of cement. The retardation rate achieved is directly dependent on the dosage rate which in turn is nfluenced by quality of cement and aggregates, w/c ratio and temperatures. It is trials should be carried out to determine optimum dosage rate.Applications conditions Instructions for useBy use SWRR-381 concrete of highest quality can be produced. The standard rules of good concreting practice, concerning production, placing and testing are to be followed. Fresh concrete must be cured as per the relevant standard.Important NotesWhen accidental overdosing of normal setting SWRR-381 occure the setting time will be retarded.During this period the concrete must be kept moist to prevent premature drying out.Other products catagories available.
