中文摘要	研究了掺50%矿渣的水泥-矿渣复合胶凝材料3 a龄期的硬化浆体C-S-H凝胶特性,结果显示:3 a龄期时矿渣反应程度为68.3%,大部分小颗粒矿渣已反应,但许多大颗粒矿渣几乎未反应;长龄期时浆体中Ca(OH)2没有消耗殆尽,从SEM图像中可以发现Ca(OH)2大量存在;水泥-矿渣复合胶凝材料体系3 a龄期的C-S-H凝胶的Ca/Si比、(Al+Mg)/Si比均值分别为1.88和0.60,相较于水泥生成的C-S-H凝胶,水泥-矿渣复合胶凝体系的C-S-H凝胶Ca/Si比较低,且含有大量Al。但Ca/Si比明显高于水泥-粉煤灰复合胶凝材料生成的C-S-H凝胶。; The 3-year characteristics of the C-S-H gel produced by hydration of cement-GGBS composite binder containing 50% slag were investigated. The results show that the reaction degree of slag is 68. 3% at the age of 3 years. Most of the small GGBS particles react heavily but many large particles remain almost unreacted. The Ca( OH)2in long-term hardened paste is not consumed completely,and a lot of Ca( OH)2can be observed in the SEM photograph. The mean Ca / Si,and( Al + Mg) / Si atom ratios of the gel in the 3-year hardened cement-GGBS paste are 1. 88 and 0. 60,respectively. The gel produced by cement-GGBS binder has a lower Ca / Si atom ratio and higher Al content than that of Portland cement paste. But the Ca / Si of the gel produced by cement-GGBS binder is much higher than that of the gel produced by cement-fly ash binder.
