Water reducing agent is a kind of concrete admixture which can reduce the water consumption of mixing under the condition that the slump of concrete is basically unchanged. The addition of concrete mix can disperse cement particles, improve its workability, reduce unit water consumption and improve the fluidity of concrete mix. Or reduce the amount of cement per unit to save cement.

Test Range
Polycarboxylic acid system high performance water reducing agent, air suction high efficiency water reducing agent, standard type water reducing agent, slow setting type water reducing agent, etc

Test item
Water reduction rate, bleeding rate ratio, gas content, difference of setting time: initial setting, 1h warp change: slump, compressive strength ratio: 7d, compressive strength ratio: 28d, shrinkage ratio: 28d, etc
