Impact-resistant and wear-resistant concrete for rapid road repair and preparation process thereof

Abstract

The invention discloses impact-resistant and wear-resistant concrete for rapid road repair and a preparation process thereof, wherein the technical scheme comprises that the impact-resistant and wear-resistant concrete comprises 150-210 parts of water, 230-290 parts of cement, 70-90 parts of fly ash, 20-60 parts of silica fume, 80-120 parts of medium sand, 70-110 parts of aggregate, 20-40 parts of propylene fibers, 10-30 parts of an expanding agent, 3-10 parts of an impact-resistant and wear-resistant agent, 5-15 parts of a polycarboxylic acid high-performance water reducing agent and 7-13 parts of a retarder. The preparation method comprises the following specific preparation steps: S1, aggregate processing; S2, mixing and stirring; and S3, adding an additive. The concrete has the beneficial effects that the impact-resistant and wear-resistant agent can improve the compressive strength and the impact-resistant and wear-resistant strength of the concrete, the wear rate is reduced due to the addition of the fly ash, the concrete has good construction performance and high impact-resistant and wear-resistant strength after hardening, and the volume dosage of the polypropylene fiber is increased, so that the concrete poured on a road is rapidly solidified and the road is repaired, and the road can be quickly put into use.

Description

technical field [0001] The invention relates to the field of concrete preparation, in particular to an impact-resistant and wear-resistant concrete for rapid road repair and a preparation process thereof. Background technique [0002] Concrete, referred to as "concrete (tóng)": refers to the general designation of engineering composite materials that use cementitious materials to cement aggregates into a whole. Aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, the cement concrete obtained by mixing is also called ordinary concrete. It is widely used in civil engineering. Concrete has rich raw materials, low price and excellent production process The simple characteristics make it more and more used. During the use of roads, various factors will often occur due to factors such as environment, geographical location, climate, and traffic loads, as well as the types of materials used, construction techniques, and designs. various disea...

AI Technical Summary

Problems solved by technology

[0005] To this end, the present invention provides a kind of impact-resistant and wear-resistant concrete for rapid repair of roads and its preparation process to solve the problem of high wear rate of existing anti-abrasion materials, low anti-abrasion strength, and high cost of raw materials. The conventional inorganic anti-abrasion materials also have poor construction performance, easy to crack in the early stage, and unprocessed aggregates affect the performance of concrete.
