摘要/Abstract

摘要： 为探究不同硅质原料对水热合成水化硅酸钙物相的影响,研究了温度和硅钙比对产物的影响。采用X射线衍射(XRD)分析了水化硅酸钙物相,并探究了不同硅质原料与Ca(OH)₂的反应效率。结果表明,不同硅质原料与Ca(OH)₂的反应效率由高到低依次为硅藻土、石英、珍珠岩;在硅藻土-石灰体系中,硅藻土中非晶态二氧化硅的Si—O更易被破坏,具有不稳定性,致使硅藻土反应效率更高。在石英-石灰体系中,随着钙硅比的提高,空气中的CO₂参与反应,生成碳硅钙石与片柱钙石,且托贝莫来石与硬硅钙石会逐渐消失,通过合理调控硅钙比和水热温度可有效地控制反应产物,这对于不同硅质原料的选择、水热合成水化硅酸钙中产物的控制及水热合成水化硅酸钙应用领域具有重大意义。

Abstract: In order to explore the effects of different siliceous materials on the phase of calcium silicate hydrate synthesized by hydrothermal method, the effects of temperature and silicon-to-calcium ratio on the product were studied. The phase of calcium silicate hydrate was analyzed by X-ray diffraction (XRD), and the reaction efficiency of different siliceous raw materials with Ca(OH)₂ was investigated. The results show that the reaction efficiency of different siliceous raw materials with Ca(OH)₂ from high to low is diatomite, quartz and perlite. In the diatomite-lime system, the amorphous silicon dioxide Si—O in diatomite is easier to be destroyed, and it has instability, resulting in higher reaction efficiency of diatomite. In the quartz-lime system, with the increase of silicon-to-calcium ratio, CO₂ in the air can participate in the reaction to generate tilleyite and scawtite, while tobermorite and xonotlite gradually disappear. The reaction product can be effectively controlled by reasonably adjusting the silicon-to-calcium ratio and hydrothermal temperature. This is of great significance to the selection of different siliceous raw materials, the control of products of calcium silicate hydrate and the application field of calcium silicate hydrate synthesized by hydrothermal method.

Key words: calcium silicate hydrate, quartz, diatomite, perlite, silicon-to-calcium ratio, temperature
