Hydroxypropyl Methyl Cellulose (HPMC) is highly pure cotton cellulose as raw materials, under the condition of alkaline specially made by etherification. It helps building materials apply more easily and perform better. They provide water retention and cohesiveness to mixtures. With special modification, it can be used to control thickening, water demand, workability, sag resistance, strength …

Effect of Hydroxypropyl Methyl Cellulose on the Performance of Foam Concrete
Following the addition of hydroxypropyl methylcellulose to 0.5% in foamed concrete, the slump decreased slightly. The data clarified that when the content of hydroxypropyl methyl cellulose does not exceed 0.05%, the participation of hydroxypropyl methyl cellulose can significantly improve the fluidity and viscosity of the foam concrete slurry. After the hydroxypropyl methyl cellulose is dissolved, …
