Research on Mechanical Properties of Recycled Fiber Concrete


Article Preview

At present, green energy saving idea, aimed at protecting environment and saving energy, now has become the guiding philosophy of modern architecture. Based on this, recycled carpet waste fibers for textile mechanical properties of concrete were discussed in this paper. The application of polypropylene fiber concrete abroad has been widely used, which is becoming more and more popularly in China recent years. Meanwhile, research on the application of recycled polypropylene fiber concrete is still scarce. The experiment of this paper adopt waste polypropylene fibers as reinforcing fiber, and we make the standard specimen which size is . We use the specimen to do the research of mechanical properties of compressive strength and observing the variation of compressive strength of concrete specimen in different fiber volume. We discovered that when we add volume of 0.12% recycled polypropylene fiber and the length is 19mm, the compressive strength of concrete increases greatly. We draw the conclusion that the compressive strength of recycled fiber concrete is better than ordinary one from the experiment. In addition, if such concrete was used widely, we may reach the goals of conserving resources and protecting the environment.
