Powder Polycarboxylate Superplasticizer SP-409
1. Good slump retention ability: Normally carboxylic groups is damaged of ordinary polycarboxylate superplasticizer by the high temperature during dry spray process, Powder Polycarboxylate Superplasticizer SP-409 takes the special process so protect the carboxylic groups and achieve the excellent slump retention ability. 2. High water reducing rate: The water reducing rate of SP-409 could achieve 25% above, under the conditions of mixing the concrete with the same ratio of the water, SP-409 could improve fluidity greatly. 3. Excellent solubility and fast solvability: Due to uniform particles, the specific area is larger, so SP-409 is dissolved quickly in the water then no impurity after dissolving.
