CEMENTITIOUS COMPOSITIONS HAVING BIOMASS ASHES, ESPECIALLY BAGASSE ASHES, AND USES THEREOF
The present invention relates to cementitious compositions comprising or consisting of a) a hydraulic binder itself comprising (in each case relative to the total dry weight of hydraulic binder) ai) 50 - 92 w%, preferably 70 - 77.55 w% of Ordinary Portland Cement, aii) 5 - 50 w%, preferably 21 - 30 w% of biomass ash, preferably bagasse ash, b) 0.01-0.5 w%, preferably 0.1 - 0.45 w% (relative to the total dry weight of the cementitious composition) of cellulose ether, c) optionally 0.05 - 2.5 w%, preferably 0.1 - 1 w% (relative to the total dry weight of the cementitious composition) of redispersible polymer powder, and d) optionally at least one activator selected from alkali metal or alkaline earth metal salts of hydroxide, formate, chloride, sulphate, and/or nitrate. The present invention also relates to uses of such cementitious compositions especially as tile adhesive
