摘要
通过对中强混凝土5种投料顺序的立方体抗压强度进行的试验研究；并对试验结果作图比较；结果表明，第⑤组试验，即砂、碎石、胶合料与水一并投料搅拌120s的投料顺序能获得最高的立方体抗压强度。图3，表1，参2。
The cube strengths of five kind of medium-strength concrete are obtained by different feeding sequences based on experimental research. The results show that the highest cube strengh of concrete can be obtained when the sands,broken stones,cementing materials and water are simultaneously feeds and mixed for 120s. 3figs., 1tab., 2refs.
