【摘要】 为了确定模型试验中的微粒型混凝土和砂浆,进行了混凝土和砂浆的试配试验,从中选出最恰当的一组配合比进行模型的制作施工,最后在完成的模型上进行了回弹法试验验证.结果表明,选用的微粒型混凝土和砂浆符合强度等级的要求.更多还原

【Abstract】 In order to determine the particulate concrete and mortar in the model test,the paper conducts the test match experiment on the concrete and mortar,and chooses the best mix proportion to build the model.After constructing the model,the rebound method is used to test the model.The result reveals that the particulate concrete and mortar is the most appropriate match to select to meet the strength grade requirement.更多还原
