EipponCell® HEMC LH640M hydroxyethyl methyl cellulose exerts a specific impact on the setting time of cement mortar, which is assessed using a consistency meter. The incorporation of hydroxyethyl methyl cellulose leads to alterations in the setting time of cement mortar. The initial setting time is shortened by 30 minutes, while the final setting time is extended by 5 minutes. This indicates that cellulose contributes to enhanced water retention, and even at a lower dosage of 0.5%, it influences coagulation time. This influence remains consistent despite variations in cellulose ether concentration. The inclusion of hydroxyethyl methyl cellulose has a marginal effect on the setting time of cement mortar, demonstrating minimal ramifications for practical engineering applications.

Application of HEMC LH 640M

KimaCell® HEMC MH40M, a type of cellulose ether, serves as a commonly employed viscosity modifier for concrete. It finds extensive application in self-compacting concrete and grout materials. This additive enhances the cohesiveness of cement-based substances and the uniformity of their solidified structure. The impact of HEMC as a viscosity modifier on the fresh characteristics, mechanical attributes, and drying shrinkage of mortar was examined. The mechanism of action was investigated based on non-evaporative water content and pore structure. Furthermore, the beneficial effect of HEMC modification in iron tailings sand cement mortar was demonstrated.

HEMC notably raises the viscosity of mortar. When used in conjunction with a water-reducing agent, it achieves controlled fluidity within an appropriate range and diminishes the rate of mortar bleeding.

As the HEMC content increases, the compressive strength of mortar specimens at 7 days and 28 days exhibits an initial rise followed by a decline, reaching its peak when the HEMC content reaches 0.3%.
