Abstract

The invention discloses a high-performance concrete, which belongs to the technical field of concrete preparation. The high-performance concrete includes the following raw materials: cement, sand, stone, water, paper tendon, rice straw, hemp knife, polypropylene fiber, polystyrene Phenolic, polysulfone resin, poly[(2-oxiranyl)-1,2-cyclohexanediol] 2-ethyl-2-(hydroxymethyl)-1,3-propylene glycol ether, SJ-101 Resin, zinc trimer acrylate. The high-performance concrete prepared by the invention has high tensile strength and compressive strength, and excellent toughness and corrosion resistance.

Description

【Technical field】 [0001] The invention belongs to the technical field of concrete preparation, and in particular relates to a high-performance concrete. 【Background technique】 [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete usually refers to the cement concrete obtained by using cement as the cementitious material, gravel and fine sand as the aggregate, mixed with water in a certain proportion, and admixtures and admixtures can also be added. Called ordinary concrete, it is widely used in civil engineering. [0003] Most of the existing concrete is made of simple cement, gravel, and fine sand mixed with water. The surface of the concrete produced in this way is prone to cracks, low in tensile strength, poor in corrosion resistance, and poor in toughness. For example, the Chinese patent application document "High Toughness Concrete Formula" (publication number:...
