Foam concrete and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to foam concrete and a preparation method thereof. The foam concrete comprises the following components in parts by weight: 40-60 parts of pretreated stone chips, 5-6 parts of a foaming agent, 5-8 parts of a foam stabilizer, 5-7 parts of fly ash, 10-20 parts of cement, 2-5 parts of silica fume and 10-35 parts of water, the pretreated stone chips are obtained by grinding stone chips and performing high-temperature ion activation. According to the invention, the TBM stone chips are taken as a main raw material, the composition structure and physicochemical properties of the stone chips are combined, and the lightweight-high-strength foam concrete is prepared under the action of the compound foaming agent after fine grinding, shaping and surface activation treatment, so that the problems of low strength and difficult foam stabilization of common foam concrete are solved; the problems of poor application ways of the TBM stone chips, low utilization rate, environmental pollution caused by wastes, time, labor and energy consumption in treatment and the like can be solved, the utilization rate of the wastes is increased, and the cost of building materials is saved.
本发明属于建筑材料技术领域，具体涉及一种泡沫混凝土及其制备方法。所述泡沫混凝土包括按重量份计的以下组分：40‑60份预处理石屑、5‑6份发泡剂、5‑8份稳泡剂、5‑7份粉煤灰、10‑20份水泥、2‑5份硅灰和10‑35份水；所述预处理石屑是石屑经过磨细、高温离子活化得到。本发明以TBM石屑为主要原料，结合石屑本身组成结构和理化特性，通过细磨、整形以及表面活化处理后在复配发泡剂的作用下制备轻质‑高强的泡沫混凝土，即解决了一般泡沫混凝土存在强度较低、稳泡困难的问题，又能够解决了TBM石屑应用途径贫乏、利用率低、废弃物污染环境、处理耗时耗力耗能等问题，提高废弃物的利用率，节约建材成本。
