Self-decorating recycled aggregate permeable concrete product and preparation method thereof

Abstract

The invention discloses a self-decorating recycled aggregate permeable concrete product and a preparation method thereof. The self-decorating recycled aggregate permeable concrete product is characterized by being prepared by compounding a recycled aggregate permeable concrete base layer and a recycled aggregate self-decorating surface layer, wherein the base layer is prepared by mixing common Portland cement, concrete or / and mortar-type building waste recycled aggregate of which the particle size is 2.36 to 9.5mm, concrete or / and mortar-type building waste recycled aggregate of which the particle size is less than or equal to 2.36mm, and water; the surface layer is prepared by mixing white cement, building waste recycled decorating aggregate being a mixture of one or two or more of sintered bricks and tiles, glass and ceramic and having a particle size of less than or equal to 2.36mm, and water. The preparation method comprises the following steps: mixing the base layer and surface layer raw materials respectively; then paving in a layered way, pressing and molding into blanks, demolding and naturally curing. The product disclosed the invention has a high mechanical property, highwater permeability, a good decoration effect and high practicability.

Description

technical field [0001] The invention belongs to the utilization of waste and the preparation of building material products, and relates to a self-decorating recycled aggregate permeable concrete product and a preparation method thereof. The self-decorating recycled aggregate permeable concrete product of the present invention is suitable for use as a (sponge) urban road construction material. Background technique [0002] At present, my country is in the critical stage of economic and social development and the peak of the urbanization process. The state's investment in infrastructure and the continuous acceleration of the urbanization process have brought two problems: First, the consumption of sand and gravel aggregates for new construction remains high. According to statistics, the annual output and sales of sand and gravel in my country are more than 10 billion tons; second, the renovation and demolition of old buildings will generate a large amount of construction waste....

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art that the resource utilization rate of construction waste is not high, the sandstone aggregates for construction are in short supply, the industrial pigments in permeable concrete products are easy to fade, and the collection of natural colored sand is difficult, and to provide a self-decorating Recycled aggregate permeable concrete product and preparation method thereof
