How does HPMC affect the performance of mortar at different temperatures?

Water retention: HPMC, as a water retainer, can prevent excessive evaporation and loss of water during the curing process. This water retention property ensures sufficient hydration of cement and improves the strength and durability of the mortar. In high temperature environments, the water reten... Read More

Is there any experimental data that can prove the specific impact of HPMC on mortar properties?

Thermal and mechanical properties: a study It shows that HPMC can improve the thermal and mechanical properties of plastering mortar. By adding different concentrations of HPMC (0.015%, 0.030%, 0.045%, and 0.060%), the researchers found that lighter materials could be produced with a weight redu... Read More

What effect does the addition of HPMC have on the durability of mortar?

Improve water retention: HPMC can significantly improve the water retention of mortar. A lower dosage of HPMC can significantly improve the water retention of mortar. For example, when the dosage is 0.02%, the water retention rate increases from 83% to 88%; when the dosage is 0.2%, the water rete... Read More
