    Analysis of the importance of HPMC for dry mix mortar(Ⅲ)

    Generally speaking, the higher the viscosity, the better the water retention effect. However, the higher the viscosity, the higher the molecular weight of MC, and its solubility will be reduced accordingly, which has a negative impact on the strength and construction performance of mortar. The highe

    Analysis of the importance of HPMC for dry mix mortar(Ⅱ)

    For particle size, the finer the particle, the better the water retention. When large particles of cellulose ether come into contact with water, the surface immediately dissolves and forms a gel to wrap the material and prevent water molecules from continuing to penetrate. Sometimes it is not evenly
