| 摘 要： | 为了合理确定混凝土中MgO的安定掺量,研究了不同MgO外掺量情况下水泥净浆、水泥砂浆和混凝土砂浆试样的压蒸膨胀率及试样的孔隙参数。结果表明,在MgO的安定掺量范围内,随养护时间的延长,试样的孔隙率明显降低,孔径均匀性、平均孔径等参数得到显著改善。研究成果对MgO混凝土的进一步研究和推广应用有指导意义。

| Abstract: | For reasonably ascertaining the balanced content of Magnesium Oxide(MgO)in concrete,the autoclave-treated expansibilities of cement paste,mortar and mortar in concrete with different light-burned MgO contents and their pore parameters are studied by tests respectively.The results show that,within balanced content of MgO,along with longer moist-cured time,the porosity reduces clearly,and the pore parameters,for instance,homogeneity of aperture and average in size of aperture,are improved significantly.The results have significant role for promoting the study and application of concrete mixed with MgO. |
