Abstract
The invention discloses an iron tailing ore bicolor composite layer water-permeable concrete and a preparation method thereof. The iron tailing ore bicolor composite layer water-permeable concrete comprises two composite layer permeable concrete layers, wherein the upper layer is a colored surface layer, and the lower layer is a plain-color structural layer; and the colored surface layer is prepared from the following components in parts by mass. By utilizing the iron tailing ores, the invention reduces the damage of natural stone extraction on the ecological environment, reduces the damage of the iron tailing ores on the environment, changes wastes into valuable substances, implements resource reutilization and circular economy, and thus, has obvious social benefit; and by utilizing the iron tailing ores, the invention can greatly lower the cost of concrete, thereby generating considerable economic benefit.
Description
technical field [0001] The invention relates to a permeable concrete building material and a preparation method thereof, in particular to a two-color combination layer permeable concrete of iron tailings and a preparation method thereof. Background technique [0002] Permeable concrete is also called porous concrete or drainage concrete. Permeable concrete was first researched and developed by Europe, the United States, Japan and other countries or regions for the defects of the original urban road surface, which can allow rainwater to flow into the ground, effectively replenish groundwater, and can Effectively eliminate products that pollute the environment such as oil compounds on the ground, and are also excellent pavement materials for protecting nature, maintaining ecological balance, and alleviating the urban heat island effect; permeable concrete is conducive to the sound development of human living environment and urban rainwater management Work with water pollution ...
