Basalt fiber reinforced aeolian sand based on MICP technology and preparation method thereof
The invention discloses basalt fiber reinforced aeolian sand based on an MICP technology and a preparation method of the basalt fiber reinforced aeolian sand. The basalt fiber reinforced aeolian sand comprises the following raw materials: every 143-160g of aeolian sand contains 0.2-1.53 g of basalt fibers, 150-200mL of bacterial liquid, 540-720mL of cementing liquid and 20-30mL of water; the preparation method comprises the following steps: firstly, disassembling basalt fibers into filaments by a stirring method, sinking the filaments into water for decomposition, uniformly stirring the filaments and aeolian sand for reinforcement treatment, then carrying out layered preparation by referring to a geotechnical test method standard (GB/T50123-2019), carrying out dehairing treatment between layers, and finally, pouring a bacterial liquid or a cementing liquid by adopting a Repeated staged tectionmethod pouring method, and then, carrying out natural air drying. The strength and the toughness of the aeolian sand can be effectively improved.
