摘　　要：矿渣MTC固化体高温下易开裂问题一直限制着矿渣MTC技术的推广应用,导致开裂的根本原因在于不同环境下矿渣MTC的水化反应速度不同从而导致水化产物存在差异。文章通过大量实验复配开发出一种新型激活剂MJH,其激活功能强大,同时又具有合适的碱性,可以控制合理的水化速度,引导和改变水化反应使之朝结构稳定的水化产物发展,很好地解决了矿渣MTC固化体高温开裂问题。The popularization and application of slag MTC (mud to cement) technology have been always restricted because of the slag MTC solidified body being easily cracked at high temperature. The basic reason causing the crack was the difference between the hydrochemical products formed at different hydrochemical reaction speeds under various environments. Through a great number of tests and compounding, a new activator MJH was developed. It has strong active function and suitable basicity, and may control the reasonable hydrochemical reaction speed to form the hydrochemical product with stable structure, thus settling well the problem of the slag MTC solidified body being cracked at high temperature.
