Cement 280,coal ash 70, graded sand 635, cellulose ether 2.5
Starch ether 0.5, early strength agent 4, redispersible polymer powder 8
Water addition 24.5%, temperature 27℃, humidity 55%
The formula is as above: the original strength is 1.5, the freeze-thaw strength is 1.0, but the open time is not good. After 20 minutes, there is no adhesion on the ceramic tile surface, and the drying strength is only 0.1. Will the moisture content of the concrete slab affect the drying strength?
