Abstract

The invention relates to the technical field of high-strength concrete, and particularly discloses C50 high-strength resin concrete and a preparation process thereof. The C50 high-strength resin concrete is mainly prepared from the following raw materials in parts by weight: 220 to 250 parts of cement, 90 to 120 parts of mineral powder, 70 to 90 parts of fly ash, 5 to 15 parts of silica fume, 720 to 780 parts of sand, 950 to 1000 parts of coarse aggregate, 7 to 10 parts of an additive, 165 to 180 parts of water, 100 to 120 parts of composite resin and 8 to 15 parts of a curing agent, the composite resin is composed of liquid phenolic resin and solid phenolic resin according to the mass ratio of (15-26): (7-10). The C50 high-strength resin concrete can be used for building, water conservancy and road and bridge engineering, and has the advantages of high strength and easiness in stirring.

Description

technical field [0001] This application relates to the technical field of high-strength concrete, more specifically, it relates to a C50 high-strength resin concrete and its preparation process. Background technique [0002] Concrete is widely used in housing construction, hydraulic engineering, road construction, bridge construction and other projects. Concrete can be divided into cement concrete, gypsum concrete, water glass concrete, Portland concrete, asphalt concrete, polymer concrete and so on according to the variety of cementitious materials. Among them, polymer concrete is a granular organic-inorganic composite material. It is a concrete composed of organic polymers (such as resins), inorganic cementitious materials and aggregates, which can improve the strength, cohesive force, and chemical corrosion resistance of concrete. performance. [0003] The Chinese patent whose application notification number is CN104261747A discloses a high-strength phenolic resin concr...
