摘要
按水灰比0.5对混凝土进行配置,研究了随着橡胶掺量的不同、粒径的不同、龄期的不同对混凝土立方体抗压强度和轴心抗压强度的影响,并进行了有限元模拟。研究表明,抗压强度均随掺量增大而大幅度减小,对小粒径影响更甚,而在后期强度增长明显高于早期强度。将试验结果与有限元模拟比较,观察到模拟模型的裂缝发展、应力分布与试验吻合。
According to the water cement ratio of 0.5,the effect of different ages of different particle sizes with different rubber content on the compressive strength of concrete cube and axial core was studied,and the finite element simulation was carried out.The results showed that the compressive strength decreases greatly with the increase of the amount of rubber particle,and the effect for small diameter was more obvious,the growth of later strength was obviously higher than that of early strength.Compared with the results from the finite element simulation,the fracture development and stress distribution of the model were agreement with test results.
