Sulfate-resistant concrete
The invention belongs to the technical field of concrete of constructional engineering, and provides a sulfate-resistant concrete for solving the problems that, in the sulfate ion severely corroded environment, concrete structure is easy to destroy, service life of the concrete is reduced, but mixing amount of the existing compound concrete antiseptic is 4% of usage amount of cementitious material, proportion is too low, antiseptic effect is difficult to realize, or various types of concretes are used in actual application, under the condition of improper control on the antiseptic, technical effects cannot be satisfactory if adding proportion is inappropriate. The sulfate-resistant concrete is prepared from the cementitious material, sand, broken stones, cement, pelletized blast furnace mineral powder 95#, silica fume, fly ash, antiseptic, water-reducing agent, corrosion inhibitor and air entraining agent according to certain proportion. The sulfate-resistant concrete has the strength of C35 standard, effectively prevents damage caused by external force and inner stress, resists corrosion of sulfate ions, and has good compactness and anti-penetrability performance, thus, durability of the concrete is increased and service life of the concrete is prolonged. The sulfate-resistant concrete is safe and reliable, and completely overcomes corrosion of sulfate ions.
