Effect of water consumption on performance of polycarboxylic acid water reducer The influence of water consumption of polycarboxylic acid water reducer is very obvious. In the practical application of concrete engineering, sometimes if the water consumption increases by 1~3kg/m3, the concrete will show serious bleeding, resulting in pitting, sanding, holes and other defects on the concrete surface. The uniformity of concrete pouring and construction quality cannot be guaranteed, resulting in the reduction of the strength and durability of the concrete structure.

Cement mortar: hpmc​ improve the dispersion of cement sand, greatly improve the plasticity and water retention of mortar, have an effect on preventing cracks and enhance the strength of cement.

Generally speaking, the higher the water reducing rate of water reducing agent is, the more sensitive the mixing logistics mobility is to the content in its effective content range.
