摘要
Abstract
In this paper,the degraded ancient building tiles were repaired by Microbial Induced Calcium Carbonate Precipitation(MICP)tech-nology.The repair effect was analyzed through physical and mechanical tests,and the appearance and composition of the repaired materials were analyzed through microscopic detection means.The test results showed that the flexural strength at the fracture of the repaired tile can reach 0.5 MPa at the highest,and the maximum ultrasonic velocity was 2.387 m/s,which indicates that the compactness of the gel at the through crack was relatively high after repair.The microscopic test showed that uniform and compact aragonite-based calcium carbonate crys-tals were deposited at the tile cracks,which had good compatibility with the tile and played a good cementation role.关键词
