Concrete efficient expending agent employing aluminum-containing industrial waste residues as well as preparation method and application of concrete efficient expending agent
The invention provides a concrete efficient expending agent employing aluminum-containing industrial waste residues as well as a preparation method and an application of the concrete efficient expending agent. According to the concrete efficient expending agent employing the aluminum-containing industrial waste residues, the solubility of active Al2O3 in the aluminum-containing industrial waste residues is increased by employing multiple excitation effects of calcium oxide, gypsum, lithium slag and triethanolamine; and the obtained expending agent can generate two expending sources, namely calcium hydroxide and ettringite through hydration reaction. The expending agent has the characteristics of calcium oxide expending agents and calcium sulphoaluminate expending agents, and has relatively large restrained expansion rate, relatively high compression resistance and breaking strength.
