Abstract

The invention relates to a corrosion-resistant concrete which is prepared from the following raw materials in parts by weight: 3-5 parts of acrylamide (AM), 10-14 parts of 2-acrylamido-methylpropanesulfonic acid (AMPS), 1-1.4 parts of dimethyl diallyl ammonium chloride, 2-3 parts of sodium dioctyl sulfosuccinate, 1-2 parts of cocamidopropyl dimethyl betaine, 300-340 parts of river sand, 160-170 parts of cement, 490-530 parts of gravel, a right amount of water and 20-30 parts of assistant. The AM and AMPS added into the concrete increase the reinforcing steel corrosion resistance of the concrete, so that the concrete has favorable moisturizing performance and lower maintenance cost. The assistant enhances the tensile strength, bending strength, compression strength and compactness of the concrete and can emit perfume and resist moths and corrosion, so that the concrete has the advantages of higher corrosion resistance, higher water resistance, higher permeation resistance, favorable water reducing effect, high plasticity and favorable pumpability.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to an anti-corrosion concrete and a preparation method thereof. Background technique [0002] The operation of the mine has certain particularity and complexity. In order to adapt to the environment of the mine, not only the concrete is required to have high strength, small deformation, good impermeability, good corrosion resistance, good frost resistance, and excellent Durability and other comprehensive performance, but also requires to minimize the wall thickness, reduce the cost of mine construction. The current concrete does not have the above comprehensive performance or the cost is high, and further improvement of performance is needed to meet the needs of my country's deepening drilling construction, while improving economic benefits and promoting faster social progress. Contents of the invention [0003] The object of the present invention is to provide an anti-corrosion...
