Microbially induced calcium carbonate precipitation (MICP) is an emerging technology proposed for soil improvement in recent years. It has environmental protection and sustainability advantages. Reinforcing fiber can effectively improve the flexibility of MICP-treated sandy material. The MICP synergistic solidified sand research results have attracted significant attention recently. This paper introduces reaction mechanism curing method MICP, including injecting soaking, spraying, pre-mixing, single-phase, step-by-step injection methods. summarizes effect various fibers, jute fiber, animal polypropylene carbon polyester polyvinyl alcohol (PVA), on sand. project summarized following results: 1) two-step improves uniformity distribution sample. 2) Adding provided more adsorption sites bacteria increased nucleation sites; 3)The fibrous network structure sample, combined with 'bridge' effect, efficient preventing cracks from expanding samples; 4) friction cohesion between itself column overall stability sample; 5) coupling sand, generated tensile strength (TS) specimens; 6) For two factors content length, unconfined compressive (UCS) greater than length. Fiber type influenced Meanwhile, development prospect was pointed out, influence pretreatment modification effect; mixed, uniform method; 3) mixing fibers properties cured specimens.

In order to promote the sustainable use of resources and reduce waste glass tailings resources. The present study focuses on a fluorite mine as research subject, utilizing coarse tailings, fine cement substitute-curing agent, recycled primary raw materials. It investigates changes in compressive strength tailing with varying sand- binder ratios content at 3-day, 7-day, 28-day intervals when filling slurry concentration is set 77% ratio maintained 2:1. findings indicate that there minimal impact test blocks using sand 4:1 below 10%. However, once exceeds 10%, significant decline occurs. Scanning electron microscope (SEM) images reveal ettringite crystal formation both 0% 25% due high levels Na
