To increase the early strength and usefulness of ground granulated blast furnace slag (GGBFS) in cement-based composites, five different chemical reagents were added to a blend of cement with 80% GGBFS at low curing times. The orthogonal design and methods of range and variance analysis were used to determine the optimal dosage and ratio of activators. The activation mechanism was ascertained by using the full-spectrum fitting of X-ray diffraction and microscopic analysis of ²⁹Si NMR. The prediction model of hydration products was given in GGBFS-cement system activated and the micromechanical properties of main hydration products C-A-S-H gel were simulated by the simulation of molecular dynamics. The results show that combined activators are better than an individual activators. The optimum combination is Ca(OH)₂ + CaSO₄ (CA) with a dosage of 3% for GGBFS mass and ratio of 3:1. The activation index with CA increase by 32.5% compared with control groups (CG) at 7d, respectively. The relative bridge oxygen characterized the degree of network structure polymerization decreases by 45% when CA is added compared with CG after a curing time of 14d. The C-A-S-H gels increase the bonding energy between the silicon chains and the calcium layer and the tensile strength.

为了提高水泥基复合材料中粉状高炉矿渣（GGBFS）的早期强度和实用性，在低固化时间下，将五种不同的化学试剂添加到含80％GGBFS的水泥混合物中。使用正交设计以及范围和方差分析的方法来确定活化剂的最佳剂量和比例。通过X射线衍射的全光谱拟合和^29的显微镜分析来确定活化机理。Si NMR。在激活的GGBFS-水泥体系中给出了水合产物的预测模型，并通过分子动力学模拟对主要水合产物CASH凝胶的微观力学性能进行了模拟。结果表明，组合活化剂比单独的活化剂要好。最佳组合是Ca（OH）₂ + CaSO ₄（CA），GGBFS质量的剂量为3％，比例为3：1。与在第7天的对照组（CG）相比，CA的激活指数分别增加了32.5％。在14d的固化时间后，与CG相比，添加CA时，表征网状结构聚合度的相对桥氧降低了45％。CASH凝胶增加了硅链和钙层之间的键能以及拉伸强度。
