Experimental results show that the compressive strength of concrete is closely related not only to the water-to-cementratio, but also to the crushing value of aggregate.
试验结果表明，混凝土抗压强度不仅与水灰比密切相关，而且与骨料压碎指标有关。

The essence of concrete framework theory is to deduce the cement dosage of unit volume concrete from frame-mortar ratio, unit water dosage and deviated function of cement-sand ratio.
混凝土架构设计理论的实质，是通过架浆比、单位用水量以及砂灰比偏离三个参数推求单位水泥用量的过程。

The effect of the amount of fiber, the length of fiber, the ratio of watertocement on tensile strength, shear strength, compressive strength and elastic modulus was investigated.
