摘要
本文主要研究了α-Ca_3(PO_4)_2-C_5H_8O_7-H_2O体系胶凝材料的凝结硬化及强度性质。研究表明,在本文实验条件下,该体系胶凝材料的硬化时间与柠檬酸(C_6H_8O_7)水溶液浓度的关系呈凹型曲线形式,当溶液浓度为2M时,硬化时间最短。而硬化体24h抗压强度与C_6H_8O_7水溶液浓度的关系呈凸型曲线形式,当溶液浓度为2.5M时,抗压强度最大,为32.25MPa。此外,文中阐述了硬化体的SEM观察和XED分析。
The setting and strength properties of the cement materials in α-Ca_3 (PO_4)_2-C_6H_8O_7-H_2O system were studied. It proved that under the experiment conditions used in our paper, therelaton between the setting time of the system cement materials and the concentration of C_6H_8O_7water solution shown concave type curve, when solution concentration was 2M, the setting time wasthe shortest. Whereas the relation between 24h compressive strength of complexes and theconcentration of C_6H_8O_7 water solution was in convex type curve, when solution concentration was2.5M, the compressive strength was 32.25MPa, which was the highest. SEM and XRD were used tostudy the complexes.
