Application Studies on Silane Hydrophobic Agents for Concrete Protection

Abstract:

In this paper, the function of silane hydrophobic agents to protect concretes under different varieties and different concentrations were studied. Penetration depth, water absorption ratio and contact angle were measured and compared, the influences of silane hydrophobic agents on the concretes protection under different condition were investigated. Results showed that silane hydrophobic agents exhibit better properties on concretes protection. 24h water absorption ratios of all silane hydrophobic agents surpassed the trade standard JC/T 902-2002 Silicone hydrophobic agent for construction surfaces, and all of the samples showed excellent static water contact angle and hydrophobic property. The protective effect of silane hydrophobic agent B is better than silane hydrophobic agent A.
