Abstract
The invention discloses concrete prepared from steel slag powder. The concrete comprises the following components in parts by weight: 155-255 parts of cement, 155-255 parts of steel slag powder, 550-780 parts of sand, 1060-1090 parts of macadam, 3.1-6.12 parts of an efficient water reducer and 180-185 parts of water, wherein the cement and the steel slag powder are same in parts by mass. According to the concrete disclosed by the invention, the concrete is prepared from the steel slag powder, so that discharge of waste can be reduced, and the quality of the concrete is beneficially improved and the production cost of the concrete is lowered. Therefore, the concrete not only has an economic benefit, but also has a social benefit.
