Method for preparing baking-free brick from tailings in machine-made sand production process
The invention discloses a method for preparing a baking-free brick from tailings in a machine-made sand production process, and belongs to the technical field of building energy-saving thermal insulation materials, and the method comprises the following steps: S1, pre-treating the machine-made sand tailings; s2, stirring treatment; s3, performing low-temperature vacuum drying treatment; s4, preparing raw materials; s5, uniformly stirring and mixing; s6, brick body forming; and S7, maintaining. The baking-free brick prepared through the method has high density, a certain synergistic effect is achieved among all the operation steps, the compressive strength and breaking strength of the baking-free brick can be remarkably improved through mutual cooperation, and the mechanical performance of the baking-free brick can be greatly improved. And the water absorption rate of the baking-free brick prepared by the method is not greatly changed within 1-7 days after being soaked in water, and the water absorption rate of the baking-free brick after being soaked in water for 24 hours is less than 20% specified in Non-Sintered Common Clay Brick Building Material Industry Standard within different soaking times. According to the baking-free brick prepared by the method disclosed by the invention, the mechanical strength is improved, and meanwhile, the waterproofness and the water absorption rate of the baking-free brick are relatively low, and the durability is excellent.
本申请公开了一种机制砂生产过程中尾渣制备免烧砖的方法，属于建筑节能保温隔热材料技术领域，包括如下步骤：S1、机制砂尾渣预处理；S2、搅拌处理；S3、低温真空干燥处理；S4、原料准备；S5、搅拌混匀；S6、砖体成型；S7、养护。本申请方法制备的免烧砖具有较高的密度，各个操作步骤之间具有一定的协同作用，相互配合能够显著提高免烧砖的抗压强度和抗折强度，能大幅度提升免烧砖的机械性能。并且本申请方法制备的免烧砖在浸水1～7d内吸水率变化不大，其在不同浸水时间吸水率满足《非烧结普通粘土砖建材行业标准》规定的浸水24h吸水率小于20％。本申请方法制备的免烧砖在提升机械强度的同时，保证了免烧砖的防水性，吸水率相对低，耐久性优异。
