Anti-skid high-strength exposed concrete and preparation method thereof

Abstract

This application relates to the field of concrete, and specifically discloses an anti-sliding high-strength exposed concrete and a preparation method thereof. The anti-sliding high-strength exposed concrete includes the following substances in parts by weight: 15-20 parts of water, 30-35 parts of cement, 90- 100 parts of coarse aggregate, 90-100 parts of fine aggregate and 0.1-0.5 part of admixture; the construction depth of the anti-skid high-strength exposed concrete is 2-3 mm. This application optimizes the structural depth of the exposed concrete material, increases the roughness to improve the anti-skid performance of the exposed concrete material, and at the same time, the coarse aggregate particles of the concrete material under the structure are firmly bonded to the exposed concrete, which improves the strength of the traditional exposed concrete material Poor problems, thus effectively improving the anti-skid performance and mechanical strength of exposed concrete.

Description

technical field

[0001] The application relates to the field of concrete, more specifically, it relates to an anti-skid high-strength exposed concrete and a preparation method thereof. Background technique

[0002] Permeable concrete is a special kind of concrete, also known as porous concrete, discontinuously graded concrete, open pore concrete or filter concrete. It is generally composed of binder, coarse aggregate, water and admixtures. Engineering materials with continuous pores and high water permeability can be used in water purification, permeable pavement, sound absorption and other projects. Exposed aggregate concrete is a concrete with exposed aggregate on the surface of permeable concrete as the decorative effect of the surface. The aggregate is exposed on the surface, and the fresh color, round luster, and good texture of the aggregate are used to achieve the aesthetic feeling of the exterior, and to achieve a natural decorative effect that is not artificially ca...
