Why should hydroxypropyl methyl cellulose(HPMC) be added in mortar

1:HPMC has excellent water retention performance, widely used in various mortars, including masonry mortar, plaster mortar and ground leveling mortar, to improve the water leakage of mortar.

2:HPMC has significant thickening effect, improve the construction performance and workability of mortar, change the fluidity of the product, achieve the desired appearance effect, improve the full degree and use volume of mortar.

3:HPMC can improve the cohesion and operability of mortar, overcome the shell of ordinary mortar, empty drum and other common problems, reduce falling material, save materials, reduce costs.

4:HPMC has a certain retarding effect, which can ensure the operating time of mortar, improve the plasticity of mortar and construction effect.

5:HPMC can introduce an appropriate amount of bubbles, can greatly improve the frost resistance of mortar, improve the durability of mortar.

6:HPMC is a combination of physical and chemical effects to play the role of water retention and thickening, in the process of hydration can produce micro-expansion performance of the material, so that the mortar has a certain micro-expansion performance, prevent the mortar in the later hydration process due to shrinkage caused by cracking, improve the service life of the building.
