Impact-resistant and wear-resistant concrete and construction method thereof

Abstract

The invention discloses impact-resistant and wear-resistant concrete and a construction method thereof. The invention relates to the technical field of concrete, in particular to the impact-resistantand wear-resistant concrete and the construction method thereof. Silicon powder is adopted, the average particle size of the silicon powder is 0.1 micron, and the impact-resistant and wear-resistant concrete has the great specific surface area, filling performance and volcanic ash activity effect; various properties of the concrete are greatly improved, so that the concrete is compact in structure, tiny cracks and bubbles in the structure are greatly reduced, the wear resistance and cavitation resistance can be improved by doping the silicon powder, and the wear resistance and cavitation resistance of the concrete added with the silicon powder can be improved by 3 times and 4 times through tests; fly ash is adopted, the fly ash has a volcanic ash activity effect and reacts with calcium hydroxide to generate calcium silicate gel, and the calcium silicate gel becomes a part of the gel; microbead spherical particles have the effects of increasing the flowability of concrete, reducing bleeding and improving the workability of the concrete.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to an impact-resistant and wear-resistant concrete and a construction method thereof. Background technique [0002] Impact and wear resistance is the durability of concrete in a special environment. It mainly occurs on the surface of high-head drainage buildings in water conservancy and hydropower projects, road surfaces, bridge decks in traffic engineering, and other parts that are in direct contact with vehicles. In recent years, in the construction and operation of many island-connecting projects, sea-crossing bridges, and river-crossing bridges, it has also been found that the sand-carrying water has the effect of scouring key parts such as bridge piers and bridge caps, which has caused serious abrasion damage to concrete. , it can be considered that the impact and wear resistance of concrete determines the safe service life and operation and maintenance costs of these building...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an anti-impact and wear-resistant concrete and its construction method, which solves the problem that the admixture is easily absorbed and surface-adsorbed by the aggregate and gel material during the preparation of the existing concrete, and cannot Make full use of the admixture, the concrete has poor wear resistance, the internal density of the concrete is low, it is easy to crack, and it is easy to cause cavitation problems
