Study on Impact Resistance of Steel Slag Fine Aggregate Concrete Based on Drop Hammer Impact Test
摘要
Abstract
To investigate the impact resistance of steel slag fine aggregate concrete,the concrete specimens were prepared by replacing fine aggregate with equal volume of steel slag at replacement rates of 10% ,20% and 30% ,respectively.The impact resistance test was carried out by drop hammer impact device to study the impact life and damage evolution law,and the impact resistance of specimen was compared with ordinary concrete.The results show that the addition of steel slag fine aggregate can improve the impact resistance of concrete,and the impact life is obviously improved when the drop weight is small.There is a certain degree of dispersion in the results of concrete impact resistance test,and the impact life of steel slag concrete conforms to Weibull distribution.Based on the Weibull distribution,the impact life under different failure probabilities is estimated,and the impact damage evolution equation is established to calculate the corresponding impact times when the concrete with different steel slag content reaches a certain damage variable.关键词
