Research of Permeable Multi-Function Treatment Agent on Concrete Surface

摘要

With modified Sodium silicate as the main raw material, adding a certain amount of penetrating agent, reinforcing agent, pH value regulators to compound different treatment agent. Brushed different treatment agent on the C40 standard concrete block surface at different periods, and exterminated the rebound strength and carbonation depth of the test blocks, impermeability test was also carried out. The results indicated that the best time to brush treatment agent was 7 days later after concrete demoulding, the compressive strength of 28th day increased by 16.6%, impermeable abilities raised a level, and the carbonation depth of the 60th day reduced by 3mm.
