A method for making a cement permeable concrete ground structure with aggregates of different colors or materials on the surface to achieve a gradient effect

Abstract

The invention discloses a cement permeable concrete ground structure and a manufacturing method with different colors or material aggregates on the surface to achieve a gradient effect. The structure is composed of a cement permeable concrete layer, a cushion layer and a base layer from top to bottom. The above-mentioned layers are from the top Arranged in order from bottom to top, the cement permeable concrete layer with exposed aggregate effect on the top layer forms a gradient effect through materials of different colors or materials and construction techniques. The method for making the ground structure includes the following steps: (1) laying the base; (2) laying a cushion on the base; (3) laying at least one cement permeable concrete layer on the cushion; (4) paving the most When the cement permeable concrete layer is on the upper layer, the cement permeable concrete layer of one color should be paved first, and then the cement permeable concrete layer of another color should be paved. The surface of the permeable concrete forms a gradient effect; (5) The surface of the uppermost cement permeable concrete layer is treated with exposed aggregate. Rinse after the retarded membrane; or directly achieve the aggregate effect by rinsing the surface of the uppermost cement permeable concrete layer; (6) Curing. The cement permeable concrete ground structure with gradient effect realized by different colors or material aggregates of the present invention is a ground structure integrating environmental protection and decoration.

Description

technical field [0001] The invention relates to a cement permeable concrete ground structure with a gradient effect achieved by aggregates of different colors or materials on the surface and a manufacturing method thereof, which belongs to the technical field of pavement pavement. Background technique [0002] At present, cement permeable concrete is widely used in the outdoor overall pavement system on the market. The apparent effect of permeable concrete is only colored and exposed aggregate. Although the effect of colored permeable concrete can achieve more colors, the apparent effect of artificial traces is obvious; while the apparent effect of exposed aggregate permeable concrete has natural and rustic characteristics. But its color is less; at the same time, in terms of construction technology: currently on the market, a straight line or a curve is formed where two colors of exposed aggregate permeable concrete are connected, and it is impossible to form the effect of ...
