Abstract Model synthetic pastes were designed to obtain a simplified silica system that could be used in durability studies on materials with low calcium-to-silica ratios. The synthetic pastes made use of the well-known pozzolanic reaction between tricalcium silicate (C3S) and nanosilica, covering calcium-to-silica ratios (C/S) from 0.8 to 3.0. The pure C3S paste (C/S = 3.0) contained C-S-H and portlandite, while pastes with C/S

模拟用于低 pH 水泥的合成糊剂

摘要模型合成浆料旨在获得一种简化的二氧化硅系统，该系统可用于对低钙硅比材料的耐久性研究。合成糊剂利用了众所周知的硅酸三钙 (C3S) 和纳米二氧化硅之间的火山灰反应，涵盖了 0.8 到 3.0 的钙与二氧化硅比 (C/S)。纯 C3S 糊状物 (C/S = 3.0) 含有 CSH 和硅酸盐，而含有 C/S 的糊状物
