Natural color-separating concrete using inorganic additives

Abstract

The invention relates to a natural color-separating concrete using inorganic additives, which comprises the following components in parts by weight: 360-380 parts of cement, 730-750 parts of river sand, 1140-1170 parts of macadam and 130-140 parts of water. The concrete also comprises a water-reducing agent accounting for 0.7-0.9 wt% of the cement, paddy ash accounting for 0-10 wt% of the cement, powdered ore accounting for 0-22 wt% of the cement, and black pigment accounting for 0-10 wt% of the cement. The raw materials are prepared into a first grey scale, a second grey scale, a third grey scale and a fourth grey scale according to the color number. The invention overcomes the defects of high cost for decoration, low durability and high fading tendency in natural environment in the existing external decoration materials. The invention does not pollute the environment, and can form elegant and natural appearance by large consumption of straws and other wastes, thereby being beneficial to the coordination and unification between the buildings and the natural environment.

Description

technical field [0001] The invention relates to a civil engineering building material, more specifically, it is a kind of concrete which adopts natural color separation of inorganic additives. Background technique [0002] The appearance of some large concrete structures is usually light gray, without any color matching, the tone is monotonous, and is extremely inconsistent with the natural environment. In order to beautify the environment, finishing works are often carried out on the exterior of the structure, such as tiling, or painting. measure. These exterior decoration materials more or less have certain defects, either the decoration cost is expensive, or the durability is poor, and they are easy to fade in the natural environment. In particular, after some large-scale structures are faded, it is difficult and expensive to redecorate them again, and they are often not reprocessed, which becomes a disharmonious factor in the environment. In particular, redecoration al...

Problems solved by technology

These exterior decoration materials have more or less certain defects, either the decoration cost is expensive, or the durability is poor, and they are easy to fade in the natural environment.

In particular, after some large-scale structures are faded, it is difficult and expensive to redecorate them, and they are often not reprocessed, which becomes a disharmonious factor in the environment.

Especially for re-decoration, it is necessary to build an external platform, especially for some large-scale concrete structures, which is extremely inconvenient. At the same time, the durability after re-decoration is also poor, and it is easy to fade in the natural environment
