PASS 150 / 150 S / 150 W admixture it is superplasticizer based on polycarboxylate acid. This product is made of selected polymers specially designed to make the water content of the concrete work more effectively to achieve concrete strength gradually until the final stage of drying with flow concrete to achieve the highest durability of concrete. This effect can be used to improve workability, to increase final strengths, or to facilitate a reduction in cement content while maintaining mix properties. PASS 150 gives high slump increase with the same amount of water.the set retarding slump retention admixtures that enhance finish quality.
