High carbon sequestration non-autoclaved aerated concrete and preparation method thereof
The invention provides high-carbon-sequestration non-autoclaved aerated concrete and a preparation method thereof, and belongs to the technical field of building materials, and the high-carbon-sequestration non-autoclaved aerated concrete comprises the following components in parts by mass: 15-50 parts of cement, 20-55 parts of steel slag, 10-30 parts of mineral slag, 5-15 parts of lime, 0-5 parts of gypsum, 20-60 parts of water, 0.1-0.4 part of a foaming agent, 0-0.5 part of a water reducing agent, 1-4 parts of an exciting agent and 0.02-0.5 part of a foam stabilizer. A large amount of solid waste steel slag and mineral slag are used as main raw materials, resource utilization of industrial waste slag is facilitated, the cement consumption in the non-autoclaved aerated concrete is reduced, the production cost of the non-autoclaved aerated concrete is effectively reduced, a variable-pressure curing process is adopted, deep mineralization reaction is facilitated, a large amount of CO2 can be directly absorbed, the carbon sequestration amount is larger than 15% of the mass of the non-autoclaved aerated concrete, and the production cost of the non-autoclaved aerated concrete is reduced. The method is an effective way for carbon utilization, the production period of the non-autoclaved aerated concrete is greatly shortened, and aerated concrete products with qualified strength can be produced in a short period.
本发明提供一种高固碳免蒸压加气混凝土及其制备方法，属于建筑材料技术领域，高固碳免蒸压加气混凝土包括以下质量份数的组分：水泥15‑50份，钢渣20‑55份，矿渣10‑30份，石灰5‑15份，石膏0‑5份，水20‑60份，发泡剂0.1‑0.4份，减水剂0‑0.5份，激发剂1‑4份，稳泡剂0.02‑0.5份。本发明以大宗固废钢渣、矿渣为主要原材料，有利于工业废渣的资源化利用，降低了免蒸压加气混凝土中水泥用量，有效降低免蒸压加气混凝土的生产成本，采用变压养护工艺，利于深度矿化反应，可直接吸收大量CO2，固碳量大于其本身质量的15％，是一种碳利用的有效途径，大大缩短了免蒸压加气混凝土的生产周期，可在短周期内生产强度合格的加气混凝土产品。
