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.

Embodiment 1

[0036] The invention provides the following technical proposal: a kind of anti-impact and wear-resistant concrete for rapid repair of roads, the raw materials of which include the following components:

[0037] 150 parts of water, 230 parts of cement, 70 parts of fly ash, 20 parts of silica fume, 80 parts of medium sand, 70 parts of aggregate, 20 parts of acrylic fiber, 10 parts of expansion agent, 3 parts of anti-abrasion agent, high polycarboxylate Performance water reducer 5 parts, retarder 7 parts, anti-scourrence agent is a compound admixture, the main function is to improve the performance of the mixture, reduce the loss of slump over time, and stimulate the potential volcanic ash of fly ash Activity, increase the amount of hydration products, improve the early strength of large-volume fly ash concrete, the anti-abrasion agent contains a small amount of water-reducing agent, which can improve the construction performance of the mixture, and the anti-abrasion agent contain...

Embodiment 2

[0044] The invention provides the following technical proposal: a kind of anti-impact and wear-resistant concrete for rapid repair of roads, the raw materials of which include the following components:

[0045] 180 parts of water, 260 parts of cement, 80 parts of fly ash, 40 parts of silica fume, 100 parts of medium sand, 90 parts of aggregate, 30 parts of acrylic fiber, 20 parts of expansion agent, 7 parts of anti-abrasion agent, high polycarboxylate 10 parts of performance water reducer and 10 parts of retarder. The anti-scouring agent is a composite admixture whose main function is to improve the working performance of the mixture, reduce the loss of slump over time, and stimulate the potential of fly ash. Pozzolanic activity, increase the amount of hydration products, and improve the early strength of large-volume fly ash concrete. The anti-scouring agent contains a small amount of water-reducing agent, which can improve the construction performance of the mixture. The anti...

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...
