摘要

通过对再生粗骨料取代率为60%,分别掺入矿粉、粉煤灰以及矿粉与粉煤灰(1∶1)双掺为10%,20%,30%的混凝土试件进行抗压强度试验,应用超声回弹检测其抗压强度,推出了超声回弹测强回归式,推动了再生混凝土无损检测技术的研究发展。
The paper undertakes the compressive strength test on the concrete specimen by mixing the mineral powder,the fly ash,and the mineral powder and fly ash(1∶ 1) whose the double mixing are respectively 10%,20% and 30%,and replacement ratio of regenerated coarse aggregate is 60%,adopts the supersonic rebound method to test its compressive strength,points out the strength-measuring regression equation,and the research development of the nondestruction test of the regenerated concrete.
