Thermal insulation aggregate and preparation method thereof
The invention relates to the technical field of aggregate preparation, in particular to a thermal insulation aggregate and a preparation method thereof.The preparation method comprises the steps that coal gangue, fly ash, limestone and water are mixed and then granulated, and raw material balls are obtained; drying the raw nodules, preheating and sintering in sequence, and carrying out alkaline leaching and calcining again to obtain the thermal insulation aggregate; according to the thermal insulation aggregate prepared by the invention, the heat conductivity coefficient of the material is remarkably reduced while the requirement on structural strength is met. When the thermal insulation aggregate is applied to manufacturing of the concrete wall, the thermal insulation function of the concrete wall can be remarkably improved, the energy consumption of a building is reduced, the production cost is low, the production difficulty is small, and large-scale production is facilitated.
本发明涉及骨料制备技术领域，尤其涉及一种保温骨料及其制备方法，本发明将煤矸石、粉煤灰、石灰石和水混合后进行造粒，得到生料球；将生料球干燥后顺次进行预热和烧结，并再次进行碱浸和煅烧后得到保温骨料；本项发明所制备的保温骨料，在确保满足结构强度要求的同时，显著降低了材料的导热系数。将该保温骨料应用于混凝土墙体的制造中，不仅能够显著提升混凝土墙体的保温隔热功能，降低建筑物的能源消耗，而且生产成本低，生产难度小，有利于实现大规模生产。
