Abstract

The invention discloses high-performance concrete for building. The concrete is prepared from the following raw materials in parts by weight: 32 to 36 parts of Portland cement, 28 to 30 parts of quartz sand, 24 to 26 parts of fly ash, 22 to 24 parts of superfine mineral powder, 18 to 22 parts of bechilite powder, 14 to 16 parts of polyethylene glycol oxide, 3 to 5 parts of titanium fiber, 4 to 8 parts of fatty alcohol-polyoxyethylene ether, 8 to 10 parts of thermal stabilizers, 3 to 4 parts of anti-aging agents, 1 to 2 parts of water-reducing agents, 2 to 3 parts of waterproof agents and 20 to22 parts of water. The high-performance concrete for building has the advantages that the concrete has excellent intensity and durability; meanwhile, the raw material ingredients are safe and non-toxic and achieve the environment-friendly effects; high practical values and good application prospects are realized.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a high-performance concrete for construction and a preparation method thereof. Background technique [0002] Concrete is one of the most important contemporary civil engineering materials. It is prepared in a certain proportion by cementitious materials, granular aggregates (also known as aggregates), water, and admixtures and admixtures added when necessary. It is a kind of artificial stone material that is uniformly stirred, densely formed, cured and hardened; concrete has the characteristics of abundant raw materials, low price, and simple production process, so its consumption is increasing. At the same time, concrete also has high compressive strength and durability. Good, wide range of strength grades and other characteristics, these characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development,...
