Microbially Induced Calcium Carbonate Precipitation Technique Progress and Review of Engineering Applications
摘要
Abstract
Soil cementation and solidification,based on microbially induced calcium carbonate precipitation(MICP)technology,has emerged as research hotspots in geotechnical engineering and geological engineering since the 21st century.In this research,the reinforcement mechanism of MICP technology and the research status of the engineering application and the reinforcement effect and application practice are systematically described and reviewed.The results show that the strength of the site after MICP solidification shows an obvious non-uniformity,and the distribution of calcium carbonate content decreases with depth.In desert environment,the calcium carbonate coating induced by in-situ extraction of bacteria demonstrates superior strength and stability to the traditional Bacillus pasteurelli.The application of new MICP technology,such as microbial cement and microbial brick,shows promising prospects in terms of strength and durability,and new vitality into the realization of China's double carbon goal.Addressing the factors affecting the precipitation characteristics of calcium carbonate by MICP technology,the uniformity of calcium carbonate distribution at field scale is enhanced,the durability of calcium carbonate skeleton under seasonal changes ensured,and curing efficiency under different environments improved,which should all be prioritized in future research.关键词
