The present invention relates to a concrete admixture comprising a carboxyl-based composite compound and a silica hybrid silicofluoride composite compound, the carboxyl-based composite compound is prepared from by-products generated in the manufacturing process of an aromatic compound, and the silica hybrid silicofluoride salt The composite compound is manufactured using low-purity TEOS, a by-product of the refining process of tetraorthosilicate (TEOS), and is made of an eco-friendly material and is a concrete admixture that can improve the durability of the constructed concrete by improving the watertightness of the concrete. It is about. |
