Method for preparing non-sintered brick from Yellow River silt
The invention relates to the technical field of environmental protection accessory devices, in particular to a method for preparing a non-sintered brick from Yellow River silt, which does not need sintering and high-temperature maintenance, lowers the energy consumption and has the compressive strength higher than MU7.5. The method comprises the following steps: 1, ; the method comprises the following steps: S1, preparing bottom mud slurry; mixing the river sediment dry powder with cement; wherein the processes of adding water, then adding a water reducing agent, mixing, adding water and adding the water reducing agent are carried out under the condition of stirring, the stirring speed is 400r/min, and the stirring time is 2min, so that the bottom mud slurry with better fluidity can be obtained, and the bottom mud slurry with the fluidity of 150-240mm is selected for later use; s2, a foaming material is manufactured, specifically, a foaming agent is sprayed to the wood board, water issprayed to the upper end, and the foaming material with the foam sinking distance smaller than 1 cm is selected for use; s3, mixing: adding the foaming material in the S2 into the bottom mud slurry inthe S1, adding an additive, and stirring at the speed of 450r/min for 25s to obtain a mixture; s4 forming.
本发明涉及环境保护附属装置的技术领域，特别是涉及一种利用黄河泥沙制备免烧结砖的方法，其无需烧结和高温养护，降低能耗，并且抗压强度大于MU7.5；包括以下步骤：S1制作底泥料浆：河道底泥干粉与水泥混合，加入水，再添加减水剂，混合、加水和添加减水剂的过程中均在搅拌的条件下进行，搅拌速度为400r/min，搅拌时间为2min，通过这种方式可以得到流动性较好的底泥浆料，选择流动度为150～240mm的底泥浆料，备用；S2制作发泡料：将发泡剂喷到木板上，上端洒水，选取泡沫沉陷距离小于1cm的发泡料，备用；S3混合：将S2中发泡料添加至S1底泥浆料中，同时添加外加剂，搅拌，速度为450r/min，持续25s，得到混合料；S4成型。
