| Abstract: | Such commonly used ready-mixed concretes as C30(non-pumping) and C30(pumping) were selected to be as controlled concretes,then the optimum substitution ratio of machine-made sand to natural sand and the corresponding optimal scales of sand proportion were studied.Furthermore,influence of the content of stone chips and the type and addition ratio of superplasticizers on the performance of machine-made sand concrete were studied respectively. |

| Keywords: | machine-made sand sand percentage ready-mixed concrete |
