Experimental research on compressive properties of concrete with different plastics content

摘要

Compression tests of five groups of concrete specimens with different plastic particles (0%, 5%, 10%, 30% and 45% aggregate volume ratio) are carried out. The results show that, the incorporation of plastic particles has significant influence on the mechanical properties of concrete. With the increase of dosage of plastic particles, the compressive strength and elastic modulus of concrete reduce gradually, but the strain corresponding to the maximum intensity shows a rising trend. In addition, the linear sections in concrete stress-strain curve disappears after adding plastic particles.
