Description
Ucoplast RP 350 is an admixture capable of acting not only as Plasticiser but which are also capable of delay setting time of concrete ensures that the cement is used more efficiently to provide workability or increased strength at reduce water content. 
Action
Ucoplast RP 350 acts as both a set retarder and as a plasticiser the plasticising action of Ucoplast- RP may Be used in several ways. 

1. If no adjustment is made to water cement ratio a high workability concrete will be obtain which is useful for difficult pours.

2. UCOPLAST RP-350 is absorbed on to the surface of C₃A and C₃S of cement which are responsible for early setting and early strength effect respectively. Thus slowing down early setting / stiffening effects in hydrating cementitious system. This effectively extends period of workability / plasticising of the concrete allows delay in the setting time and modifies the hydration to produce optimum crystal growth with fewer pores giving higher strength, reduced permeability and greater durability.

Where to use 

• For Raft foundation, slip form structure tunnels etc. To avoid cold joints.
• For difficult pore and congested Steelwork
• In high summer, warmer climates.
• Ready mixed concrete for long hauls / hot weather concreting
• Pumped concrete - to offset problems due to break down delays

Method of Use
Ucoplast-RP 350 a should be added with the gauging water in sufficient time to ensure that it is distributed evenly through out the entire batch.
The dosage rate is 150 ml-250 ml. Optimum dosage should be determined by site trials Overdosing would lead excess set retarding beyond the range quoted.
Storage Life
One year if kept in manufacturer sealed drums under shade. Protect from frost & direct sunlight.
Health & Safety
UCOPLAST - RP 350 is an industrial chemical mildly alkaline, prolonged contact with skin should be avoided.
