镁盐对含微生物水泥净浆性能的影响研究
Research on influence of magnesium salt on properties of cement paste containing microorganism
摘要
Abstract
The researches in recent years indicate that the technology of carbonate precipitation inducing by microorganism can be used to ameliorate the internal structure of concrete materials, thus heightening its physical property. In this paper, the influ-ence of magnesium salt on compressive strength, water absorption ratio and crack filling of cement paste containing microorganism was researched, and the X-ray diffraction method was performed to analyze the components of precipitation. The results indicate that the addition of magnesium in the immersion solutions increased compressive strength and decreased water absorption ratio for both the sulpho-aluminate cement paste and the ordinary silicate cement paste that contain microorganism, and also a plump mineral filling belt was formed in the crack. The mineralization precipitation contains both calcite carbonate and magnesia carbon-ate and the later is really rare, which can promote the mineralization process of cement paste containing microorganism.关键词
