Shield muck sintered ceramsite modifier and method for sintering ceramsite by shield muck
The invention belongs to the technical field of building materials, and particularly relates to a shield muck sintered ceramsite modifier and a method for sintering shield muck into ceramsite, firstly urea formaldehyde resin, calcium carbonate, calcium sulfate and bentonite are sequentially added and mixed to prepare the modifier, and then the modifier is added into shield muck and uniformly stirred to obtain modified shield muck; adding the improved shield muck into a pelletizer to prepare raw material balls, firing the raw material balls, and naturally cooling the raw material balls to room temperature to prepare the lightweight porous high-strength ceramsite. The construction waste is recycled, the concept of'waste-free city 'and'recycling resource' is met, and the improved ceramsite fired by the shield muck has the advantages of being porous, light and high in strength and can be used as concrete aggregate to replace traditional gravel.
本发明属于建筑材料技术领域，具体涉及一种盾构渣土烧制陶粒改良剂及盾构渣土烧结陶粒方法，先将尿素甲醛树脂、碳酸钙、硫酸钙、膨润土按顺序加入混合制成改良剂，再将改良剂加入盾构渣土中搅拌均匀得到改良后的盾构渣土；然后将改良后的盾构渣土加入造球机中制得生料球进行烧制后自然冷却至室温，制得轻质多孔高强度陶粒；将建筑垃圾资源化，符合“无废城市”和“循环资源”的理念，而且改良后的盾构渣土烧制的陶粒具有多孔、轻质、强度大的优点，可作为混凝土骨料替代传统碎石。
