Study on the Influence of Polypropylene Fiber on Compressive and Crack Resistance of Lightweight Aggregate Concrete
In order to investigate the effect of adding polypropylene fiber on the material properties during the preparation of lightweight aggre-gate concrete,polypropylene fiber lightweight aggregate concrete specimens were prepared with different fiber content and different ash ceram-ide content,and compressive strength tests were carried out.The test results show that the compressive strength of the prepared lightweight ag-gregate concrete can be affected by adjusting the content of pulverized coal ash ceramics,the content and length of polypropylene fiber.When 0.7%polypropylene fiber is added,the effect of compressive strength growth is the most intuitive,and the effect of compressive strength growth is the most obvious when the fiber length is 9 mm.
