The invention belongs to the field of building materials, and particularly discloses foam concrete and a preparation method thereof. The foam concrete provided by the invention is prepared from the following raw materials: cement, fly ash, fine sand, modified loofah sponge, a foaming agent, a foam stabilizer, a water reducing agent, an adhesive and water, the surface of the modified loofah sponge is coated with a reinforcing material, and the reinforcing material comprises carbon nanotubes and calcined kaolin. According to the preparation method, the surface of the loofah sponge fiber is modified after the carbon nano tube and the calcined kaolin are compounded, and the loofah sponge fiber, the cement, the fly ash, the fine sand and other raw materials are jointly used for preparing the foam concrete. The comprehensive performance of the foam concrete in the aspects of durability, compression resistance, sound absorption, heat preservation and the like is remarkably improved.
本发明属于建材领域，具体公开了一种泡沫混凝土及其制备方法。本发明提供的泡沫混凝土包括以下原料：水泥、粉煤灰、细砂、改性丝瓜络、发泡剂、稳泡剂、减水剂、黏合剂和水；所述改性丝瓜络为表面涂覆增强材料的丝瓜络，所述增强材料包括碳纳米管和煅烧高岭土。本发明通过将碳纳米管和煅烧高岭土复配后对丝瓜络纤维表面进行改性，与水泥、粉煤灰和细砂等原料共同制备一种泡沫混凝土，与其他泡沫混凝土相比，本发明提供的泡沫混凝土在耐久性、抗压、吸声和保温等方面的综合性能均得到显著提升。
