SM-P ASTM C 494, Type F Melamine-based Superplasticizer(Powder),Sulfonated Melamine Formaldehyde Polymer For Concrete admixtures SM-P Description SM-P is one of the best existing concrete admixtures in comprehensive properties. It conforms to the requirements of chemical admixture specifications for concrete: ASTM C 494, Type F, GB8076-1997. Uses ? SM-P is recommended strongly for use in all ready-mix, precast, and prestress concrete applications where low water-cement ratio, low permeability, high durability, high strength concrete is specified or high slump flowable concrete is required. ? SM-P can be applied in various concrete, including high strength concrete, high fluidity concrete, high duration concrete, aluminate cement refractory concrete, grouting material, steam curing concrete, high strength mortar, gypsum products, and so on. Advantages 1. Increase concrete early strength. 2. Promote workability. 3. Increase flowability. 4. Increase cohesiveness and segregation resistance. 5. Shorten mold take-off time. 6. Keep water/cement to a minimum. 7. Promote air stability. 8. Compatible with cements, gypsums and other admixtures. 9. Reduce bleeding at high slumps.
