Embodiment 1

[0010] Example 1: Steel slag is composed of steel slag with a particle size of 0.6mm, steel slag with a particle size of 0.28mm, steel slag with a particle size of 0.08mm and steel slag with a particle size of 0.07mm, and the mass ratio is 1:0.68:0.56:0.31 , The reason why such a gradation is used can minimize the porosity in the concrete, thereby improving the wear resistance of the concrete.

Embodiment 2

[0011] Example 2: Steel slag is composed of steel slag with a particle size of 0.58mm, steel slag with a particle size of 0.3mm, steel slag with a particle size of 0.076mm and steel slag with a particle size of 0.075mm, and the mass ratio is 1:0.68:0.56:0.31 .

Embodiment 3

[0012] Example 3: Steel slag is composed of steel slag with a particle size of 0.45mm, steel slag with a particle size of 0.3mm, steel slag with a particle size of 0.1mm and steel slag with a particle size of 0.065mm, and the mass ratio is 1:0.68:0.56:0.31

[0013] When the concrete of the present invention is made, the above-mentioned materials are firstly shaken and smoothed, then sprayed with a curing agent (or covered with film plastic), the process cycle is kept at about 2-3 days, and finally it is formed by stirring with a mixer Stirring time was kept at 45s / square.

[0014] The effects achieved by the present invention are as follows: 1. The formed floor has high hardness, good wear resistance, and can withstand heavy pressure and impact. 2. No sand, no dust, keep the floor clean. 3. The surface is smooth and bright, and the anti-slip effect is good. 4. Excellent water resistance and oil resistance, suitable for various dry and wet internal and external environments. ...

Abstract

The invention discloses a high strength abrasion-resistant concrete, in particular to a concrete for construction. The high strength abrasion-resistant concrete provided by the invention is composed of steel slag, a cementitious material, water and a water reducing agent, wherein the cementitious material consists of cement accounting for 45% of the mass of the cementitious material, mineral powder accounting for 20% of the mass of the cementitious material, and silicon carbide accounting for 5% of the mass of the cementitious material. The steel slag and the cementitious material are in a mass ratio of 1.67:1, and the water and the cementitious material are in a mass ratio of 0.2:1. The concrete made by the invention has the advantages of high hardness and high abrasion resistance, also has good water resistance and oil resistance, and is suitable for various dry and wet internal and external environments.

Description

technical field [0001] The invention relates to a concrete, especially a high-strength wear-resistant concrete. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. However, the existing concrete is a heterogeneous porous material. Under the erosion of carbon dioxide, water, chloride ions, sulfate and other media, it will inevitably be corroded by external factors, and the concrete will be destroyed at an accelerated rate, and the service life will be greatly improved. To solve this problem, the applicant of this patent researched and developed a wear-resistant co...
