摘要:
本文采用了导热量热法、DSC、TGA、DTA、SEM—EDXA 以及 X-射线分析等方法研究了 C_3A-CaSO_4·2H_2O-CaCO_3-H_2O 及 C_3S-CaCO_3-H_2O 等系统的水化和显微结构特征。发现 CaCO_3明显加速了C_3A 与石膏的反应,首先形成钙矾石,石膏提前耗尽。在钙矾石向低硫型硫铝酸钙转变的同时碳铝酸钙明显生成。细分散的 CaCO_3还加速了 C_3S的水化并随掺量增加而加快。水化产物生长在碳酸钙颗粒表面,对 C_3S 水化起晶核作用并改善了界面粘结。
Abstract:
Hydration and microstructural characteristics of C_3A-CaSO_4·2H_2O- CaCO_3-HO_2 and C_3S-CaCO_3-H_2O systems are investigated by conductive calorimetry,DSC,TGA,DTA,SEM-EDXA and X-ray diffraction,it is shown that calcium carbonate significantly accelerates the reaction between C_3A and gypsum.Ettringite forms preferentially and the exhaustion of gypsum is advanced.The formation of calcium carboaluminate hydrate is evident while ettringite converts to the monosulphoaluminate hydrate.Finely divided calcium carbonate also accelerates the hydration of C_3S and the effect increases with dosage.The hydrate products grow on the calcium carbonate particles.It acts as a nucleating effect for hydration of C_3S and improves the bond of interface.
