橡胶混凝土抗冲击性能研究
Impact Resistance Research on Rubberized Concrete
摘要
Abstract
The impact resistance of rubberized concrete was studied using a drop-weight test.The rubber particles that were 40 mesh and 60 mesh replaced fine aggregate in concrete at equal volume substitution and the dosage of rubber particles were 10%,20%and 30%,which was used to contrast to the ordinary concrete.Experimental results indicate that the rubber particles can effectively improve the impact resistance,decrease the brittleness of concrete.In view of the variation of impact test result,the Weibull distribution is adopted to analyze the experimental data.It is proved that the impact resistance of the concrete material can be described by Weibull distribution.The natural logarithm of initial and final crack impact frequency is used to evaluate the impact resistance of rubberized concrete.On the condition of the equal failure probability, there is a close correlation between the impact resistance of rubberized concrete and the dosage of rubber particles.The rubberized concrete with the rubber particles that is 40 mesh performs better impact resistance than that is 60 mesh.关键词
