在研究具有水硬性表面层和惰性内核复合结构的深加工处理石英集料对砂浆界面区结构的改进效果,比较深加工处理石英砂浆(MTQS)、普通石英砂浆(MQS)和硬化水泥浆体(HCP)等3种试样强度随养护时间变化的基础上,研究了界面区结构对水泥砂浆强度的影响.结果表明:使用深加工处理石英集料能有效地改进界面区薄弱结构;界面区结构对水泥砂浆的早期强度影响较小,但对后期强度影响较大;改进界面区结构能大幅度提高水泥砂浆的抗压强度和抗折强度.
To study the effect of deep-processed quartz aggregates with a hydraulic surface layer and an inert core composite structure on the interface structure of the mortar, and to compare deep-processed quartz mortar (MTQS), ordinary quartz mortar (MQS) and hardened cement paste (HCP) The influence of the interface zone structure on the strength of the cement mortar was studied on the basis that the strengths of the three kinds of samples varied with the curing time. The results show that the use of deep processing quartz aggregates can effectively improve the weak structure of the interface area; the interface area structure has little effect on the early strength of the cement mortar, but has a great influence on the later strength; improve the structure of the interface area can greatly improve the cement mortar Compressive strength and flexural strength.
