Foam concrete based on calcium slag carbonization and preparation method thereof
The invention discloses foam concrete based on calcium slag carbonization, which is mainly composed of the following components in percentage by mass: 15-25% of siliceous raw material, 5-15% of calcium slag, 60-80% of lightweight aggregate, 60-65% of water and 10-20% of foam, based on the total mass of the siliceous raw material and the calcium slag, the water accounts for 60-65% of the total mass of the siliceous raw material and the calcium slag, and the foam accounts for 10-20% of the total mass of the calcium slag and the lightweight aggregate. The use amount of the foam is 4-6% of the total mass of the two, and the density of the foam is 4.7-5.3 * 10 <-2 > g/cm < 3 >. According to the concrete, a large amount of stainless steel slag and steel slag can be consumed, high-value utilization of waste slag is achieved, the use amount of cement is reduced, meanwhile, part of carbon dioxide is solidified through carbonization reaction, and carbon emission reduction can be achieved; the invention further discloses a preparation method of the foam concrete. The method is simple in process, low in production cost and short in production period.
本发明公开了一种基于钙渣碳化的泡沫混凝土，主要由硅质原料、钙渣、轻集料、水和泡沫组成，其中所述硅质原料、钙渣、轻集料的质量百分含量分别为15～25％∶5～15％和60～80％，以硅质原料和钙渣总质量计，水的用量为二者总质量的60～65％，泡沫的用量为二者总质量的4～6％，所述泡沫的密度为4.7～5.3×10‑2g/cm3。该混凝土能消耗掉大量的不锈钢渣和钢渣，实现废渣的高值化利用，减少水泥的用量，同时，碳化反应固化了部分二氧化碳，可以实现碳减排；还公开了上述泡沫混凝土的制备方法，该方法工艺简洁，生产成本低，生产周期短。
