Waterproof anti-cracking agent for concrete
The invention provides a waterproof anti-cracking agent for concrete, which comprises the following raw materials in parts by weight: 30-45 parts of plaster, 3-8 parts of mineral clinker, 20-35 parts of coal gangue, 25-35 parts of pulverized fuel ash and 0.2-0.4 part of complexing agent, wherein the coal gangue comprises one or more of coal-fired slag, mud coal slag, thermal power plant and sulfur fixation ash, and the complexing agent comprises one or more of ethylenediamine tetraacetic acid compound and ethylenediamine tetraacetic acid salt compounds. The invention provides a preparation method of the waterproof anti-cracking agent for concrete, and the preparation method comprises the step of mixing the plaster, mineral clinker, coal gangue, pulverized fuel ash and complexing agent to obtain the waterproof anti-cracking agent for concrete. In the waterproof anti-cracking agent for concrete, the cracking of the concrete due to contraction can be effectively compensated through the interaction of the plaster, mineral clinker, coal gangue and the complexing agent, so that the waterproof anti-cracking agent for concrete has a better anti-cracking effect.
