Details

GH-9 is the product, by reacting among dual-carboxylic acid groups, sulfonate groups, tricalcium aluminate and tricalcium silicate. Under the performance of adherence, chelation, dispersing and madefaction, at the initial stage of hydrating of cement slurry, by dispersing the cement particles through electric double layer, solvent membrane is formed between particle surface and Ca2+which shall adhere to tricalcium aluminate as a priority, so as to retard the hydrating of cement significantly, but less adhering to the tricalcium silicate which contribute to the development of late cement strength.
