| Abstract: | The experimental results show that the effect of water-binder(cement flyash ground slag) ratio and admixture and cementing material content on the slump of fresh mix is considerably evident, and the effect of the crushed coarse aggregate type on the conpressive strength of the concrete is evident.Finally,one of mix proportions with good slump(200 mm) and higher compressive strength(80.5 MPa) is optimized,in which cement content is only 450 kg/m 3.1fig.,3tabs.,4refs. |
