Problems solved by technology

However, the strength, corrosion resistance, and heat insulation effect of the concrete prepared in this way are poor. In some situations that require high temperature operations and require insulation through concrete walls, it is difficult for traditional concrete to achieve good heat insulation effects.

Abstract

The invention discloses a preparation method of building concrete. The method comprises steps as follows: (1) preparation of raw materials: cement, gravel, sand, coal gangue, sepiolite powder, steel-like fiber, a swelling agent, water and a water reducing agent are taken, wherein a preparation method of the sepiolite powder comprises steps as follows: sepiolite is dried after being subjected to acid pickling, the dried sepiolite is ground and sieved by a sieve of 100 meshes, and the sepiolite powder is obtained; (2) dry mixing; (3) wet mixing: a mixture B is put in a stirrer, water is added tothe stirrer, the mixture is stirred uniformly and slurry concrete is prepared. The sepiolite powder is added to the raw materials of the concrete, so that the concrete has good characteristics of sepiolite and has the characteristics of good corrosion resistance, thermal stability and strength, and a building prepared from the concrete has a good thermal insulation function.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a method for preparing concrete for construction. Background technique [0002] Concrete is the most widely used building material in modern buildings. The traditional concrete preparation method is to prepare concrete by mixing cement, gravel and sand in proportion. However, the strength, corrosion resistance, and heat insulation effect of the concrete prepared in this way are poor. In some situations that require high temperature operations and require insulation through concrete walls, it is difficult for traditional concrete to achieve good heat insulation effects. . Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a method for preparing concrete for building with good thermal insulation effect of the prepared concrete. [0004] In order to achieve the above object, the present inven...
