Manufacturing method of microorganism reinforced nano-material mixed calcareous sand
The invention discloses a manufacturing method of microorganism reinforced nano material mixed calcareous sand, and relates to the technical field of microorganism mineralization. The manufacturing method comprises the following specific steps: 1, preparing calcareous sand; 2, preparing a nano material; 3, mixing the materials; 4, preparing mortar; 5, carrying out microorganism reinforcement; and 6, carrying out curing ending. According to the invention, a MICP improvement liquid is adopted to perform microbial reinforcement on calcareous sand, so that the physical and mechanical properties of the calcareous sand are enhanced, and the engineering performance of the calcareous sand is improved; and by combining the advantage that a nano material can improve the mechanical properties of raw materials, cemented calcareous sandstone can be obtained by generating calcium carbonate through microbial induction, wherein the uniaxial compressive strength of the cured calcareous sand sample can reach the megapascal level, the mechanical property can be kept stable for a long time, toxic by-products are not generated under the microorganism curing effect, and the cost required by microorganism curing engineering is lower than that required by using materials such as cement and asphalt.
