摘要:
|
提出了一种新的硅烷浸渍混凝土防水效果的混凝土表面吸水量现场评价方法,并试验研究了这种方法对不同的硅烷浸渍混凝土防水性能的评价效果。结果表明,采用这种方法计算出的2h平均渗透系数可有效反映硅烷的防水效果。

A new method to evaluate on site the waterproofing effect of silicane immersed concrete by way of meas urement of surface soakage is proposed,which has been tested and studied to assess its evaluation results of the water proofing performance of different types of silicane immersed concrete.The results indicate that the average permeability coefficient of 2 hours calculated by using the proposed method can effectively reflect the waterproofing effect of silicane.
