| description | The invention relates to the technical field of sprayed concrete, and discloses low-resilience high-performance sprayed concrete based on a composite gel system and a construction method.The low-resilience high-performance sprayed concrete based on the composite gel system comprises a sprayed concrete main material and interface treatment mortar; the sprayed concrete main material is prepared from the following raw materials in parts by weight. By doping the stone powder, the workability of the sprayed concrete can be improved, the compactness can be increased, the strength of the concrete is further improved, the stone powder is formed by processing rocks mined by tunnel boring, and the production cost is reduced. By doping the basalt fiber, the abrasion resistance and the crack resistance of the concrete are improved. The spraying of the interface treatment mortar improves the bonding strength and compressive strength of the sprayed concrete and rock or a base plane, and prevents the sprayed concrete, espec |
