Sintering-free lightweight aggregate and preparation method thereof and lightweight concrete
The invention relates to the technical field of concrete preparation, in particular to a sintering-free lightweight aggregate and a preparation method thereof and lightweight concrete. The sintering-free lightweight aggregate is prepared from the following raw materials in parts by weight: 90-110 parts of expanded polystyrene, 40-60 parts of construction waste powder, 40-50 parts of epoxy resin, 8-10 parts of an epoxy diluent, 1-2 parts of an epoxy defoaming agent, 20-30 parts of reinforcing powder and 8-10 parts of an epoxy curing agent. The preparation method comprises the following steps: (1) preparing an epoxy base material; (2) preparing an epoxy preparation solution; (3) preparing prepared lightweight aggregate; (4) preparing sintering-free lightweight aggregate; and (5) preparing the sintering-free lightweight aggregate. The sintering-free lightweight aggregate disclosed by the invention can be used for preparing lightweight concrete, and has the advantage of reducing energy consumption. The preparation method disclosed by the invention has the advantage of improving the mechanical property of the sintering-free lightweight aggregate.
本申请涉及混凝土制备的技术领域，更具体地说，它涉及一种免烧结轻骨料及其制备方法和轻质混凝土。免烧结轻骨料，由包含以下重量份的原料制成：90‑110份发泡聚苯乙烯、40‑60份建筑垃圾粉末、40‑50份环氧树脂、8‑10份环氧稀释剂、1‑2份环氧消泡剂、20‑30份增强粉末以及8‑10环氧固化剂；其制备方法为：（1）制备环氧基料；（2）制备环氧预备液；（3）制备预备轻骨料；（4）制备预备免烧结轻骨料；（5）制备免烧结轻骨料。本申请的免烧结轻骨料可用于制备轻质混凝土，其具有减少对能量的消耗的优点；另外，本申请的制备方法具有提高免烧结轻骨料的力学性能的优点。
