High-performance anti-freezing concrete and preparation method thereof
The invention discloses high-performance anti-freezing concrete and a preparation method thereof, and relates to the technical field of concrete preparation and production. The high-performance anti-freezing concrete comprises the following components by weight: 1200-1500 parts of aggregate, 150-180 parts of cement, 50-80 parts of mineral powder, 7-12 parts of a superplasticizer, 2-5 parts of an air entraining agent, 4-6 parts of an antifreeze agent, and 140-160 parts of water, wherein the aggregate comprises stones, medium sand and fine sand in a mass ratio of (4-5): (2-3): 1. The preparationmethod of the high-performance anti-freezing concrete comprises the following steps: S1, pre-dispersing an aggregate; S2, dispersing powder; S3, dispersing an aqueous solution; and S4, dispersing fibers. The anti-freezing concrete has the technical effects that the anti-freezing performance of concrete can be stably improved and the comprehensive performance is excellent.
