Cement grade HPMC

The changes of CEMENT GRADE HPMC curves with viscosity of 100, 150 and 200 Pa.s are basically the same. When the content is 0.05%-0.15%, the water retention rate increases linearly, and when the content is 0.15%, the water retention rate is greater than 93%. When the content of Cement grade HPMC exceeds 0.20%, the increasing trend of water retention rate becomes gentle, indicating that the content of Cement grade HPMC is close to saturation. The influence curve of Cement grade HPMC with a viscosity of 40 Pa.s on the water retention rate is approximately a straight line. When the content is greater than 0.15%, the water retention rate of the mortar is significantly lower than that of the other three viscosity Cement grade HPMCs with the same content.
