As an additive for cement mortar, the cellulose ether usually has an addition amount not more than 2% of cement mass. For the study on cellulose ether, there has been a long history of research abroad. For example, DOW had successfully developed and marketed as early as 1938. First, the higher viscosity the cellulose ether.. read more →
