High-strength wear-resistant concrete and preparation method thereof

Abstract

The invention relates to the field of concrete, and particularly discloses high-strength wear-resistant concrete and a preparation method thereof. The high-strength wear-resistant concrete is prepared from the following raw materials in parts by weight: 28-42 parts of cement, 72-86 parts of river sand, 95-115 parts of gravel, 5-12 parts of fly ash, 10-20 parts of water, 4.2-6.8 parts of an additive, 2-8 parts of filling fibers and 5-15 parts of a wear-resistant filler, the wear-resistant filler is composed of rubber powder and coated aluminum nitride in a weight ratio of 1: (1-4); the preparation method comprises the following steps: weighing the cement, the river sand, the gravel and the fly ash, and uniformly mixing and stirring to prepare a primary mixture; weighing the filling fiber, the wear-resistant filler and the primary mixture, and uniformly mixing and stirring to obtain a mixture; weighing water, an additive and the mixture, mixing and stirring uniformly to obtain a mixture, and pouring and curing the mixture to obtain a finished product. The advantages of high strength and wear resistance are realized.

Description

technical field [0001] The application relates to the field of concrete, more specifically, it relates to a high-strength wear-resistant concrete and a preparation method thereof. Background technique [0002] Concrete generally refers to the use of cement as the cementitious material, sand and gravel as the aggregate, mixed with water; it can be used in building construction, bridge construction, marine engineering, machinery manufacturing and other fields. [0003] For applications such as road traffic, heavy factories, airport runways, and large pipeline linings, concrete is required to have high strength and good wear resistance. Under large load conditions, ordinary concrete is prone to long-term wheel load Under the action of repeated frictional resistance, the concrete will be worn and deteriorated to varying degrees, thus affecting the service life of the concrete. [0004] Therefore, there is an urgent need to prepare a concrete with high strength and wear resistan...
