HEMC MH40M

Specification of HEMC MH40M

Application of HEMC MH40M

KimaCell^® HEMC MH40M Cellulose ether is a commonly used concrete viscosity modifier. It is widely used in self-compacting concrete and grouting materials. It can improve the cohesion of cement-based materials and the uniformity of hardened structure. The effect of HEMC as a viscosity modifier on the fresh properties, mechanical properties, and drying shrinkage of mortar, and the mechanism of action were analyzed according to the non-evaporating water content and pore structure, and the positive effect of HEMC modification in iron tailings sand cement mortar was demonstrated.

HEMC will significantly increase the viscosity of mortar, and its combined use with water reducing agent can control the fluidity in an appropriate range and reduce the bleeding rate of mortar.

With the increase of HEMC content, the compressive strength of mortar specimens 7d and 28d first increased and then decreased, and reached the maximum when the HEMC content was 0.3%.
