Abstract

The invention provides a color steel slag road pavement brick and a preparation method thereof, and relates to the technical field of production of road pavement bricks. The color steel slag road pavement brick comprises a surface layer and a bottom layer, wherein the surface layer is prepared from the following raw materials in parts by weight: 17 to 25 parts of cement, 25 to 30 parts of steel slag molding sand, 18 to 20 parts of quartz sand, 5 to 10 parts of crushed stone, 3 to 6 parts of volcanic ash, 3 to 5 parts of zeolite, 3 to 6 parts of red mud, 4 to 6 parts of mixture, 0.2 to 0.4 part of quick setting agent, 1.3 to 2.3 parts of early strength agent, 0.5 to 1.5 parts of alkaline efforescence-resistant agent, 0.3 to 0.5 part of pigment powder, 1.2 to 1.6 parts of water reducing agent and 1 to 3 parts of water; the bottom layer is prepared from the following raw materials in parts by weight: 16 to 25 parts of cement, 22 to 28 parts of steel slag molding sand, 19 to 25 parts of crushed stone, and 2 to 3 parts of water. The preparation method comprises the following steps of weighing the raw materials, manufacturing the surface layer, manufacturing the bottom layer, forming, demolding, stacking and curing. The color steel slag road pavement brick and the preparation method can solve the problems of failure to reutilize the wastes, poor water permeability, low compressive strength, long manufacturing time, whitening, alkaline efforescence discoloring of the surface layer, and the like.

Description

technical field [0001] The invention belongs to the technical field of pavement brick production, and in particular relates to a colored steel slag pavement brick and a preparation method thereof. Background technique [0002] Industrial steel slag is the main component of urban waste, accounting for about 15%-20% of the total urban waste. At present, industrial steel slag is treated mainly by traditional open-air stacking and deep excavation and landfill. Although this method has a large processing capacity, is convenient and simple, and has low processing costs, it actually occupies a large amount of land resources and causes irreversible environmental pollution. [0003] As a paving material, pavement bricks have a wide range of applications and a huge daily consumption of raw materials. It is urgent to find other alternative materials to save the development and utilization of raw materials. [0004] The application of industrial steel slag to pavement bricks not only s...
