Abstract

The invention discloses a high-wear-resistant concrete material as well as a preparation method and application thereof. The concrete material is prepared from the following materials in parts by weight, 45 to 55 parts of silicate cement, 23 to 31 parts of fine sand, 11 to 19 parts of polystyrene resin, 7 to 15 parts of cellulose diacetate, 15 to 25 parts of dimethyl sulfoxide, and 18 to 26 partsof vermiculite. The preparation method comprises the steps that the vermiculite and cellulose diacetate are mixed and crushed, and then mixed with a dimethyl sulfoxide solution, heated and sealed forstirring, a precipitate is collected by centrifugation, pretreated vermiculite is obtained by washing and drying the precipitate; the precipitate is added with a polystyrene resin to conduct ball milling, mixed with silicate cement and fine sand, and evenly mixed; pouring, vibrating, and curing are conducted. The high-wear-resistant concrete material has higher compressive strength and flexural strength, has significant improvement in VC value, impermeability grade, freeze-thaw strength, ultimate tensile, adiabatic temperature rise, chemical attack resistance and the like, effectively improvesimpact resistance, effectively improves resistant to erosion and abrasion, effectively reduces shrinkage deformation of concrete, improves crack resistance, and has excellent overall performance.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a highly wear-resistant concrete material and its preparation method and application. Background technique

[0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. However, ordinary cement concrete has disadvantages such as low compressive and flexural properties, low durability against environmental corrosion, and poor wear resistance. Especially in water conservancy projects, especially in large-scale water conservancy projects, concrete is the most important building material. T...
