Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether commonly used in the construction industry, especially in the manufacture of concrete and mortar.

Improve water retention: HPMC can improve the water retention capacity of concrete, prevent water from evaporating too quickly during construction, and thus ensure uniform hardening of concrete.

Improve workability: HPMC can increase the fluidity and plasticity of concrete, making it easier to pour and form, while reducing water seepage.

Enhance adhesion: HPMC can improve the adhesion between concrete and the formwork, reduce adhesion during demolding, and make demolding easier.

Reduce cracks: Due to the water retention properties of HPMC, the water loss of concrete during the hardening process can be reduced, thereby reducing the occurrence of cracks.

Extend working time: HPMC can extend the workable time of concrete, allowing construction workers more time for pouring and leveling.

Improve durability: HPMC can improve the durability of concrete, making it more resistant to environmental factors such as temperature changes, humidity changes, etc.

Improve surface quality: The surface of concrete using HPMC is smoother, surface defects are reduced, and the appearance quality of concrete is improved.

Reduce material waste: Since HPMC can improve the water retention and workability of concrete, it can reduce material waste caused by improper construction.

The use of HPMC can be adjusted according to the formula and construction requirements of different concrete to achieve the best construction effect.
