摘要 通过热重-差热分析和X射线衍射以及无接触式电阻率测定仪,研究了使用复合吸水材料内养护对水泥水化性能和微观结构的影响。结果表明:与未掺复合吸水材料水泥浆相比,通过复合吸水材料进行内养护的水泥浆体7、28d水化程度更高;硬化期,更高的电阻率值可能意味着内养护对体系水化促进而使结构更密实。 The effects of internal curing with compound absorbent materials(CAMs) on hydration and microstructure of cement were studied by thermogravimetric-differential thermal analysis(TG-DTA),X-ray diffraction(XRD) and electrodless resistivity measurement.The results showed that the hydration degree of cement pastes with internal curing at 7 days and 28 days were promoted.The higher resistivity of cement paste at hardening stage may indicate a denser microstructure.
