Lightweight carbide slag cement-based material and preparation method thereof
The invention provides a light carbide slag cement-based material and a preparation method thereof, and belongs to the field of buildings. The invention provides a lightweight carbide slag cement-based material, which is prepared from the following raw materials in parts by mass: 50 to 80 parts of cement, 5 to 40 parts of carbide slag, 1.5 to 10 parts of liquid foam and 20 to 32 parts of water. Calcium hydroxide in the carbide slag can capture CO2 together with cement during carbonization maintenance of the prepared lightweight carbide slag cement base material, so that resource utilization of the carbide slag is realized, and the carbonization efficiency is improved. Besides, pores are introduced into the cement concrete through the foaming agent, so that the diffusion velocity of CO2 during carbonization maintenance is improved, the carbonization uniformity, the carbonization efficiency and the carbon sequestration rate are improved, and meanwhile, the light weight of the carbide slag cement-based material is realized.
本发明提供了一种轻质电石渣水泥基材料及其制备方法，属于建筑领域。本发明提供了一种轻质电石渣水泥基材料，以质量份数计，包括以下制备原料：水泥50～80份、电石渣5～40份、液态泡沫1.5～10份和水20～32份。电石渣中的氢氧化钙可以在制备轻质电石渣水泥基材碳化养护时同水泥一起捕获CO2，这既实现了电石渣的资源化利用，又提高了碳化效率。此外，通过发泡剂在水泥混凝土中引入了孔隙，改善了碳化养护时CO2的扩散速度，提高了碳化的均匀性、碳化效率和固碳率，同时实现了电石渣水泥基材料的轻质化。
