本研究研究了水玻璃、氢氧化钠和碳酸钠三元活化剂活化炉渣的反应动力学、反应产物和抗压强度。考虑碳酸钠含量（SCC）、水固比（WSR）、水玻璃模量（WGM）和水玻璃含量（WGC）等因素，采用田口法设计了9种混合物，并应用方差分析（ANOVA）方法对实验结果进行了评估。结果表明，三元活化剂决定反应动力学，碳酸钠主导反应产物的凝胶结构，而水玻璃用量是抗压强度的决定因素。根据分析结果，提出了三元碱活化剂的最佳配比（SCC 4%、WGC 2.5%、WGM 1.1-1.5、WSR 0.4）。 (C) 2015 Elsevier Ltd. 保留所有权利。
This study investigates the reaction kinetics, the reaction products and the compressive strength of slag activated by ternary activators, namely waterglass, sodium hydroxide and sodium carbonate. Nine mixtures are designed by the Taguchi method considering the factors of sodium carbonate content (SCC), water to solid ratio (WSR), waterglass modulus (WGM) and waterglass content (WGC), and the experimental results are evaluated by applying the analysis of variance (ANOVA) method. The results show that ternary activators determine the reaction kinetics, sodium carbonate dominates the gel structure of reaction products, while the waterglass dosage is a determinant of the compressive strength. Based on the analyzed results, an optimal proportion of ternary alkali activators (SCC 4%, WGC 2.5%, WGM 1.1-1.5 and WSR 0.4) is proposed. (C) 2015 Elsevier Ltd. All rights reserved.
