Technical Field
The invention relates to the technical field of concrete, in particular to high-strength concrete.
Background
Concrete is a generic term for engineering composites where aggregates are cemented into a whole by cementitious materials. The concrete is cement concrete, also called common concrete, which is obtained by mixing cement as cementing material and sand and stone as aggregate with water (containing additive and admixture) in a certain proportion and stirring, and is widely used in civil engineering. These characteristics make it very widely used, not only in various civil engineering, that is shipbuilding, machinery industry, ocean development, geothermal engineering, etc., but also concrete is an important material.
Concrete in the prior art is not accurate enough in batching, often can take place intensity inadequately, and the condition that often breaks or frost crack takes place under some special circumstances, and some concrete that intensity is higher, manufacturing cost is higher again.

In order to solve the technical problems, the technical scheme provided by the invention is as follows: the high strength concrete includes common Portland cement 410-containing material 500 weight portions, coarse aggregate 1250-containing material 1450 weight portions, fine aggregate 450-containing material 550 weight portions, water 270-containing material 280 weight portions, antifreezing agent 21-25 weight portions, slag 160-containing material 240 weight portions, silica fume 70-90 weight portions, water reducing agent 5-6 weight portions, and anticracking fiber 1.5-2.0 weight portions.
As an improvement, the coarse aggregate comprises 1000-1100 parts of gravel and 150-350 parts of pebbles.
As an improvement, the crushed stones and the pebbles need to be screened by a stone screening machine, and the particle size of the crushed stones and the pebbles is between 4.75mm and 5.75 mm.
As an improvement, the fine aggregate comprises 350-450 parts of lake sand and 100 parts of mountain sand.
As an improvement, the crushed stones and pebbles need to be screened by a stone screening machine, and the particle size of the crushed stones and pebbles is below 4.75 mm.
As an improvement, a defoaming agent and a thickening agent are added in the production process.
As an improvement, the anti-crack fiber is polypropylene fiber.
After the formula is adopted, the invention has the following advantages: the concrete produced by the method has the advantages of high strength and low cost, and is produced by mixing and stirring a plurality of coarse aggregates, a plurality of fine aggregates, slag and silica fume, so that the quality and the strength of the concrete are ensured, the production cost is greatly reduced by adding the slag and the silica fume, and the method is suitable for popularizing and using the method for producing the concrete.
