| 摘 要： | RbC的绝干密度、吸水率和混合料拌和用水量随粉煤灰掺量的变化趋势，与Rb用量为60％的RbC基本相同。当粉煤灰掺量为25％时，RbC的绝干密度降低10．1％，吸水率提高43．9％，混合料拌和用水量增加35．5％，变化幅度均高于Rb用量为60％的RbC。

| Abstract: | Here is a study on the physical and mechanical properties of the naturally conserved regenerated fly-ash concrete.The result from the study indicates that fixing the amount of the regenerated raw materials and admixing proper amount of fly-ash can improve the compression strength of the regenerated concrete and the improved effects vary according to the ingredients and their different amounts of the regenerated raw materials.With the increase of the added amount of the fly-ash,the maximum values of the bone... |
