Abstract

The invention provides anti-seepage acid-resisting concrete and a preparation method thereof. The anti-seepage acid-resisting concrete is prepared from the following components in parts by weight: 380 to 470 parts of cement, 530 to 630 parts of quartz sand, 800 to 900 parts of basalt, 175 to 190 parts of water, 30 to 40 parts of coal gangue micro powder, 70 to 80 parts of coal ash, 60 to 70 parts of silica fume, 280 to 330 parts of water glass, 200 to 250 parts of synthetic cement, 35 to 45 parts of sodium fluosilicate, 5 to 9 parts of hollow glass fiber and 8.1 to 12.2 parts of additive; the preparation method of the anti-seepage acid-resisting concrete adopts a manner of adding materials in batches, and the stirring time is reasonably adjusted; the anti-seepage acid-resisting concrete provided by the invention is reasonable in component matching structure, the preparation method is simple and effective, and the problems of seepage resistance and acid resistance of concrete are effectively solved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an anti-seepage and acid-resistant concrete and a preparation method thereof. Background technique [0002] Concrete is one of the most commonly used building materials. It is an engineering composite material that binds aggregates into a whole by cementitious materials. Generally, cement is used as cementitious material, sand and stone are used as aggregate, mixed with water (may contain admixtures and admixtures) in a certain proportion, and obtained by stirring. It is widely used in civil engineering. In some special industries, such as the chemical industry, acid-proof tanks and electroplating tanks often have performance requirements for concrete such as impermeability and acid resistance, but ordinary impermeability and acid-resistant concrete has poor impermeability and short service life, which seriously affects Production cost and production efficiency.
