Solid-waste-based cementing material, method for predicting 28-day compressive strength of solid-waste-based cementing material and application of solid-waste-based cementing material
The invention provides a solid-waste-based cementing material, a method for predicting 28-day compressive strength of the solid-waste-based cementing material and application of the solid-waste-based cementing material. The method comprises the four steps of preparing the solid-waste-based cementing material, testing the material, establishing a prediction model and predicting the compressive strength. The material comprises mine strong brine, fly ash, desulfurized gypsum, coal gangue, mineral powder, lime, carbide slag and a mineralization enhancer, wherein the mineralization enhancer comprises calcium formate, sodium lactate and sodium hydroxide. The material can be used for filling coal mine goaf surface collapse. The method gives consideration to simplicity, convenience and high accuracy, and is more suitable for practical application. The material not only can reduce pollutants in highly mineralized mine water, but also can make up for surface collapse of a goaf, and on the premise of meeting the requirements of low cost and environmental protection, the degradation of ecological functions of a coal mining area is saved.
本发明提供了一种固废基胶凝材料、预测其28天抗压强度的方法及应用，该方法包括制备固废基胶凝材料、材料测试、建立预测模型和预测抗压强度四个步骤。该材料包括矿井浓盐水、粉煤灰、脱硫石膏、煤矸石、矿粉、石灰、电石渣和矿化增强剂，其中矿化增强剂包括甲酸钙、乳酸钠和氢氧化钠。该材料能够用于填充煤矿采空区地表塌陷。该方法兼顾了简便性和高准确度，更加适用于实际应用中。该材料既能够降低高度矿化矿井水中的污染物，又能够弥补采空区的地表塌陷，在满足了低成本和绿色环保的需求前提下，挽救了煤炭采矿区生态功能的退化。
