不同时间和温度效应下硅烷偶联剂改进集料抗水浸润性能研究

Study on the improvement of water infiltration performance of silane coupling agent in different time and under temperature effect

通过接触角试验和水煮法试验,研究不同固化时间和固化温度下,硅烷偶联剂对集料的改进作用。试验结果表明,在一定的时间和高温作用下,硅烷偶联剂能明显提高集料表面与水之间的接触角,降低集料表面的沥青剥落程度,有效地提高集料的抗水浸润性能和粘附性能。

By means of silane coupling agent,contact angle test and water boiling test were used to study the effect of silane coupling agent on building stone in different curing time and test temperature. Experimental results show that under a certain time and high temperature,silane coupling agent can obviously improve the building stone surface contact angle with water,reduce the degree of asphalt spalling and effectively increase the building stone water infiltration resistance and adhesion properties.
