Surface treatment is an effective strategy to reduce concrete water absorption and improve concrete durability in practical engineering application. In this paper, ethyl silicate and anhydrous alcohol mixed solution is chosen as surface treatment for concrete, and water absorption is tested, the test results show that ethyl silicate can effectively reduce the concrete water absorption and water absorption rate. water absorption rate reduction rate is 82.4 for T5 and 84.6% for T7, the initial rate of water absorption is reduced 94.9 for T5 and 94.7% for T7, and the secondary rate of water absorption is reduced 73.2 for T5 and 80.1% for T7.
