EipponCell® HEMC LH 615M cellulose ether proves to be highly advantageous for air-entrained concrete, a novel lightweight wall material celebrated for its exceptional physical and mechanical properties, thermal performance, and energy-saving attributes. However, a significant drawback arises when plastering air-entrained concrete walls, as the plaster tends to develop cracks and hollow spots, hindering the further advancement of air-entrained concrete products. The primary reason behind the ease of cracking and hollowing in air-entrained concrete plastering mortar lies in its high water absorption rate, which renders it powdery, weak, and challenging to bond effectively with mortar. In response to the flaws of ordinary air-entrained concrete plastering mortar, EipponCell® HEMC LH 615M cellulose ether and polyethylene-vinyl acetate redispersible latex powder are skillfully mixed into the mortar. This innovative blend significantly addresses the challenges faced during plaster application. The inclusion of KimaCell® HEMC MH15M cellulose ether and redispersible latex powder in the mortar substantially improves water retention, ensuring the mortar retains moisture for extended periods during application. This enhanced water retention capability mitigates premature drying and evaporation, thereby maintaining the mortar's workability for a longer duration. Furthermore, the incorporation of EipponCell® HEMC LH 615M cellulose ether and redispersible latex powder substantially bolsters the bonding strength of the mortar with the air-entrained concrete surface. This strengthened adhesion fosters a more robust and durable plaster-concrete bond, thereby reducing the occurrence of cracks, hollow spots, or detachment over time.
