机制砂在生产过程中不可避免地会产生一些石粉,而石粉含量对混凝土性能会产生一定的影响,混凝土企业尤其应该关注石粉对中低强度混凝土性能的影响。本文就以设计强度为C30和C40的机制砂混凝土为例,对不同石粉含量配制的机制砂混凝土的工作性能和力学性能进行了检测,对其结果进行分析研究,得出石粉的最佳掺量,对混凝土的生产极具指导意义。
In the process of production, some sand powder will inevitably be produced in the process of production of sand, while the content of stone powder will have a certain impact on the performance of concrete. Concrete enterprises should pay particular attention to the influence of stone powder on the performance of medium and low strength concrete. In this paper, the design strength of C30 and C40 of the sand as an example, the preparation of different stone content of the performance of the mechanical properties of sand and concrete were tested, the results were analyzed and concluded that the best volume of stone powder , The production of concrete is very instructive.
