| Abstract: | This paper carried out the indoor experiment according to the different flakiness content and particle size specimens of cement concrete, including slump, compressive strength, flexural strength, permeability resistance and dry s performance of road hrinkag cement e performance. It emphasized and analyzed the effect rule of flake aggregate on the concrete. According to the results of laboratory test, it put forward the recommended range of technical indicators for aggregate flakiness content and particle size. |
