摘　　要：制备了一种以γ-C2S为主要矿物的新型水泥——自粉化低碳水泥,采用加速碳化技术使其硬化,研究了自粉化低碳水泥的制备方法、碳化后的力学性能及微观结构。研究表明:该水泥烧成温度为1 350℃,碳化后强度高(8 h抗压强度达到90 MPa以上)。该水泥低碳且自粉化,具有节能减排的特点。A type of cement named self-pulverized low carbon cement with γ-C2S as a main mineral was prepared. The preparation method and mechanical properties and microstructure of the low carbon powder were investigated by accelerated carbonation technology. The results show that the cement firing temperature is 1 350℃ and the early strength is great （i.e., The compressive strength at 8 h is 〉 90 MPa）. The cement clinker is self-pulverizing and has a feature of energy saving and emission reduction.
