Abstract

The invention discloses a preparation process of high-strength wear-resistant concrete. The concrete is prepared from the following components in parts by weight: 300 to 400 parts of Portland cement,500 to 900 parts of fine aggregate, 950 to 1250 parts of coarse aggregate, 180 to 190 parts of water, 20 to 40 parts of silica powder, 50 to 80 parts of epoxy resin, 5 to 12 parts of steel fiber, 1 to4 parts of a water reducing agent, 6 to 12 parts of an accelerator, 0.15 to 0.6 part of an air entraining agent and 40 to 65 parts of metakaolin. The structure of the concrete is scientific and reasonable; the preparation method is safe and convenient to use; and the prepared concrete is high in strength and not prone to damage during heavy pressing and collision, the overall strength of the prepared concrete during use is improved, the wear resistance of the concrete is improved, and the setting rate of the concrete is increased, so the market competitiveness of the prepared concrete is improved.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a preparation process of high-strength wear-resistant concrete. Background technique [0002] Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, uniformly stirred, compacted and cured. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete; [0003] At present, when the existing concrete on the market is in use, when it is subjected to a large external collision, it is prone to concrete fracture, and contacting and friction with hard objects for a long time will cause the surface of the concrete to shatter and affect the use of concrete. Contents of the...
