微生物成矿学的新进展——微生物诱导碳酸盐结晶,受到岩土工程和土木工程材料研究人员的高度重视。其中产脲酶微生物快速诱导大量碳酸盐结晶的过程更是近年研究的热点。与一般纯粹化学作用生成的碳酸钙不同,这种微生物诱导碳酸盐结晶的生成速度及材料强度可控,达到了土木工程应用中胶凝和封堵材料的基本标准,在一定条件下,可以替代水泥、石灰、环氧等传统材料。我国从事岩土工程和土木工程材料的研究人员也在最近十多年积极开展了该技术的研究工作,但多局限于技术应用层面上的研究,尚缺乏对微生物成矿学原理及其在土木工程材料环境中作用机理的深入工作。通过对国内外文献中岩土材料环境下几种典型的微生物成矿学原理的总结,以期促进该课题应用基础研究工作的进一步深入。
New Advances in Microbial Mineralization - Microbial Induced Carbonate Crystallization, Highlighted by Researchers in Geotechnical and Civil Engineering Materials. The process of urease-producing microorganisms rapidly inducing a large amount of carbonate crystals is a hot spot in recent years. Unlike pure calcium carbonate produced by pure chemical action, this microorganism induces the formation rate of carbonate crystals and material strength to be controlled, reaching the basic criteria of gelling and plugging materials for civil engineering applications. Under certain conditions, Alternative cement, lime, epoxy and other traditional materials. Researchers engaged in geotechnical engineering and civil engineering materials in our country have also actively carried out the research on this technology in the recent ten years. However, most of them are limited to the research on the application of technology. However, there is a lack of understanding of the principles of microbial mineralization and their application in civil engineering Working Mechanism of Engineering Material Environment. By summarizing several typical microbiological mineralogical principles in geomaterials environment in domestic and foreign literature, it is hoped to further promote the application of basic research on this subject.
