摘要
为研究塑料颗粒骨料对混凝土力学性能的影响,采用MTS322加载装置对6种不同塑料颗粒掺量的混凝土进行了四点弯拉单调加载试验。试验结果表明,随着塑料掺量的增大,掺塑料颗粒混凝土抗拉强度和初始弹性模量逐渐降低,而峰值应变则逐渐增大,应力应变曲线逐渐平缓。
In order to study the effect of plastic granule aggregate on the mechanical properties of concrete,a four-point bending test was carried out on the concretes of six different plastic granules by MTS322 test machine.The test results show that,with the increase of plastic content,the tensile strength and elastic modulus of plastic-filled concrete are gradually reduced,while the peak strain is obviously increased,and the stress-strain curve is more gentle.
