Mechanical Performance Research on Modified Cement Concrete with Recycled Plastic Particles

摘要

In order to improve the concrete performance and research the greenmaterial, the recycled ABS/PC plastic particles will be added into the cement concrete as a modifier. In this research, the C30 cement concrete was taken as the basic material, the fine aggregate in cement concrete was substituted by different amounts of recycled plastic particles. The change law of mechanical performance indexes (including cubic compressive strength. Splitting tensile strength, bending strength) were researched. The research result showed the recycled plastic particles, as a modifier, can improve mechanical performance of the cement concrete greatly. In the five addition amounts, including 0%, 2%, 5%, 8%, 11%, the three mechanical strengths will all increases at first then decreases with the addition amount increasing. When the addition amount is 5%, the three mechanical strength indexes will all reach the maximum.
