Abstract

The invention discloses a phosphate tailing-based baking-free brick and a preparation method thereof. The phosphate tailing-based baking-free brick comprises the following components: phosphate tailings; cement clinker; and water and a water reducing agent. The preparation method comprises the following steps: pretreating a phosphate tailing raw material; putting the pretreated phosphate tailings, the cement clinker and the water reducing agent into a stirrer according to the proportion, and mixing and stirring to obtain a dry mixture; adding water into the dry mixture, and then continuously stirring to obtain a mixture; pressing the mixture into a green brick; and curing the green brick to obtain the finished baking-free brick. By means of the technical means, the problems that land resources are occupied and environmental pollution is generated due to accumulation of the phosphate tailings can be effectively solved, and meanwhile recycling and recycling of the phosphate tailings are achieved. In addition, according to the technical scheme, the preparation cost of the concrete solid brick can be reduced, the environmental influence is reduced, and good application prospects are achieved.
