Method for preparing unfired lightweight aggregate from shield waste slurry
The invention discloses a method for preparing unfired lightweight aggregate from shield waste slurry, which comprises the following components in percentage by mass: 55-65% of shield waste slurry, 20-25% of construction waste, 15-20% of mineral powder and 2-3% of an excitant. The method comprises the following steps: step 1, selecting raw materials; step 2, stirring and processing; step 3, injecting into a grinding tool; step 4, carrying out sand making processing; step 5, storing and placing; wherein in the step 1, 55%-65% by mass of shield waste slurry, 20%-25% by mass of construction waste, 15%-20% by mass of mineral powder and 2%-3% by mass of excitant are selected; the method is safe and reliable, the preparation method is simple and easy to implement, low in energy consumption, lowin cost and high in production efficiency, processing and production of the unfired lightweight aggregate prepared from the shield waste slurry are facilitated, and the shield waste slurry is subjected to resource utilization and scientific treatment, so that the shield waste slurry is reduced, harmlessly processed, recycled and stabilized, the cost is low, energy is saved, and the environment isprotected.
本发明公开了一种盾构废浆制备免烧轻骨料的方法，配方包括：盾构废浆、建筑垃圾、矿粉和激发剂，各组分的质量百分含量分别是：55％‑65％的盾构废浆、20％‑25％的建筑垃圾、15％‑20％的矿粉和2％‑3％的激发剂；包括以下步骤，步骤一，原料选取；步骤二，搅拌加工；步骤三，注入磨具；步骤四，制砂加工；步骤五，存储放置；其中上述步骤一中，按照各组分的质量百分含量分别是：55％‑65％的盾构废浆、20％‑25％的建筑垃圾、15％‑20％的矿粉和2％‑3％的激发剂进行选取；该发明，安全可靠，制备方法简单易行，能耗低，成本低，生产效率高，方便盾构废浆制备免烧轻骨料加工与生产，且将盾构废浆进行资源化利用，科学处理使其减量化、无害化、资源化和稳定化，成本低，且节能环保。
