对陶粒表面进行憎水处理可以降低陶粒的吸水率 ,从而有利于改善轻集料混凝土的性能 .试验结果表明 ,ZH溶液相比于常用的憎水溶液和防水涂料 ,能非常明显地降低页岩陶粒的吸水率 ,并且使用简单、成本低廉 .进一步的试验结果显示 ,以ZH溶液和G溶液复合的方式 ,还能有效降低页岩陶粒 6h以上的吸水率 .
Hydrophobic treatment on the ceramsite surface can reduce the water absorption rate of ceramsite and thus improve the performance of light aggregate concrete.The results show that compared with the commonly used hydrophobic solution and water repellent coating ZH solution can significantly reduce the page Water absorption rate of rock ceramsite, simple to use and low cost.Further experimental results show that the combination of ZH solution and G solution can effectively reduce the water absorption rate of shale ceramsite more than 6h.
