High toughness construction material

Abstract

The invention discloses a high toughness construction material. The high toughness construction material comprises the following raw materials in parts by weight: 40 to 60 parts of silicate cement, 20 to 40 parts of composite carbon fiber, 30 to 55 parts of admixture, 3 to 5 parts of dispersant, 1 to 3 parts of water reducer, 1 to 3 parts of thickening agent, 0.5 to 3 parts of flexibilizer, 0.3 to 0.8 part of antifoaming agent, 1 to 5 parts of fire retardant, 3 to 8 parts of mica powder, 10 to 15 parts of calcium carbonate, 5 to 10 parts of fly ash, 3 to 8 parts of silicon powder, 2 to 6 parts of talcum powder, and 3 to 10 parts of calcium lignin sulfonate. A composite fiber material and a dispersant are added, the composite fiber material is evenly dispersed under the effect of the dispersant, the reinforcing and crack-resistant effects of fiber can be better exerted, the toughness and crack resistant property of material are enhanced; the mechanical properties are changed, the performance of the material on resisting deformation is prominently reinforced, the possibility of cracking and breaking of concrete is reduced, the using effect is good, the construction material has high completeness when being applied to buildings, and the cost of buildings is largely reduced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-toughness building material. Background technique [0002] Materials used in buildings are collectively referred to as building materials. New building materials include a wide range, including thermal insulation materials, heat insulation materials, high-strength materials, and materials that can breathe, all of which are new materials. Building materials are a general term for materials used in civil engineering and construction engineering. Building materials can be divided into structural materials, decorative materials and some special materials.

Problems solved by technology

Concrete is the most widely used building material. Its main components include cement, admixtures and aggregates. It is hardened after adding water and stirring. It has the advantages of simple process and waterproof performance. However, it is a brittle material with tensile and Low bending strength, small deformation capacity, and poor toughness may l
