Experimental Study on the Ratio of the Eco Concrete Cementitious Materials
The 42.5 grade sulfoaluminate cement was taken as the research object,the modification treatment was carried out,and the optimization of the mix proportion of eco concrete was studied.In response to the problems of high alkalinity in eco concrete ecological slope protection,which cannot meet the requirements of plant,as well as the compressive strength.Different mineral admixtures were selected for trial mixing tests of cementitious materials to measure the performance.The results indicate that sulfoaluminate cement is feasible to be the main component of the cementitious materials;That adding mineral admixtures to cementitious materials can reduce alkalinity,but the effect is not significant;Gypsum has stronger alkali control ability than other mineral admixtures,and the compres-sive strength of the prepared eco concrete also reached an ideal level;Adding 5％silica fume,20％gypsum,and 15％mineral powder to sulfoaluminate cement can achieve ideal alkalinity and compressive strengt.
