Concrete interface agent
A concrete interface agent relates to the technical field of concrete surface protection, an ingredient of the concrete interface agent comprises 55 to 100 parts by weight of a nano-calcium salt solution and a nano-SiO2 precursor, 0.1 to 0.4 parts by weight of a surfactant, 30 to 60 parts by weight of a silane coupling agent and 10 to 40 parts by weight of a polydimethylsilane, an ingredient of the nano-calcium salt solution comprises 2 to 5 parts by weight of a calcium hydroxide, 2 to 5 parts by weight of an acid catalyst and 200 to 500 parts by weight of an alcohol-based organic solvent, which can form a coating layer with higher hydrophobic angle on the concrete surface, reduce the water absorption of the concrete, and is not easy to crack after drying, which has more protective effect and longer service life than the existing TEOS interface agent.
