Abstract

The invention discloses an aerated concrete prepared from copper smelting water quenching slag and titanium white slag. The invention is characterized in that the aerated concrete is composed of the following components in percentage by mass: 20-50% of copper smelting water quenching slag, 14-17% of quicklime powder, 15-45% of quartz sand, 10-15% of cement clinker, 3-6% of titanium white slag, 0.06-0.1% of aluminum powder, 0.05-0.1% of foam stabilizer, 0.3-1% of water reducing agent, 1-2% of modifier, and water which is 0.3-0.5 time of the total components above. The invention aims to successfully apply the industrial waste residue copper smelting water quenching slag, titanium white slag and other industrial wastes to the aerated concrete industry, thereby solving the problems of waste of resources and environmental pollution to some extent.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of industrial waste to produce building materials, in particular to an air-entrained concrete prepared by using copper smelting water quenching slag and titanium white slag and a preparation method thereof. Background technique [0002] Titanium dioxide slag is iron-containing calcium sulfate produced by mixing low-concentration waste sulfuric acid with the by-products of lime and titanium dioxide during the production of titanium dioxide by the sulfuric acid method. About 10 tons of titanium white slag are produced by producing 1 ton of titanium dioxide, and nearly 20 million tons of titanium white slag are produced every year in the country. Compared with natural gypsum, titanium white slag is Fe 2 o 3 content and loss on ignition are high while CaO, MgO, SO 3 Low, when used as a retarder in building material cement, the setting time is short, the water consumption of standa...
