| 摘 要： | 在粗集料掺量相同的前提下,变动混凝土的粗集料级配和水胶比,以考察粗集料级配对混凝土强度发展历程的影响.试验结果表明:从提高混凝土强度的角度,随着混凝土水胶比的降低,其胶凝材料用量增大,同时,宜采用最大粒径较小的粗集料,反之亦然.

| Abstract: | The effect of coarse aggregate size distribution on concrete strength development process was studied, while keeping the coarse aggregate content constant and alterating the coarse aggregate size distribution and water to binder ratio.Experiment results show that, in order to fa- cilitate concrete strength development ,when lowering the concrete water to binder ratio ,coarse aggregate with smaller maximum size should be adopted, and vise verse. |

| Keywords: | concrete coarse aggregate size distribution water to binder ratio maximum size |
