Preparation method of filling cementing material
The invention discloses a preparation method of a filling cementing material. The preparation method comprises the following steps: preparing the filling cementing material formed by a plurality of solid wastes in different proportions; respectively carrying out compressive strength tests on the filling cementing materials formed by the solid wastes with different proportions; taking the proportion of each solid waste as an independent variable, taking the compressive strength value of the filling cementing material as a dependent variable, and fitting to establish a function model between the compressive strength and the proportion of the solid waste; establishing a cost optimization model of the filling cementing material; determining constraint conditions of the cost optimization model, wherein in the constraint conditions, the function model meets the compressive strength required value of the filling cementing material; and solving the cost optimization model by utilizing constraint conditions, and obtaining an optimal solid waste material ratio of the filling cementing material, which meets a compressive strength required value and has the minimum cost. The filling cementing material prepared by the preparation method meets the strength requirement and is relatively low in cost.
本发明公开了一种充填胶凝材料制备方法，包括以下步骤：制备由不同配比的多种固体废料形成的充填胶凝材料；对不同配比的固体废料形成的充填胶凝材料分别进行抗压强度试验；以每种固体废料的占比为自变量，以充填胶凝材料的抗压强度值为因变量，拟合建立抗压强度和固体废料占比之间的函数模型；建立充填胶凝材料的成本优化模型；确定成本优化模型的约束条件，在约束条件中，函数模型满足充填胶凝材料的抗压强度要求值；利用约束条件对成本优化模型求解，并获得满足抗压强度要求值且成本最小的充填胶凝材料的最优固体废料配比。本发明的充填胶凝材料制备方法制备的充填胶凝材料在满足强度要求的同时兼具较低的成本。
