Thermal-insulation sound-insulation lightweight foamed concrete material and preparation method thereof
The invention discloses a thermal-insulation sound-insulation lightweight foamed concrete material which is prepared by the following steps: cleaning and drying waste concrete, and performing graded cutting and crushing on waste concrete blocks to obtain waste concrete powder; adding 20-60 parts of the waste concrete powder, 2-15 parts of modified light particles, 2-3 parts of an auxiliary agent and 5-6 parts of a foaming agent into water, and uniformly mixing under a mechanical stirring condition to obtain a concrete material; pouring the concrete material into a mold, and curing in a curingchamber with the temperature of 15-25 DEG C and the humidity of 85-90% for 24 hours to obtain a formed test piece; and demolding the formed test piece, and curing for 28 days in a curing chamber withthe temperature of 15-25 DEG C and the humidity of 85-90% to obtain a finished product of the thermal-insulation sound-insulation lightweight foamed concrete material. The production cost is reduced,resources are saved, social benefits are improved, and the method is suitable for large-scale application and popularization. Good toughness and sound insulation and heat preservation performance arerealized.
本发明公开了一种保温隔音轻质发泡混凝土材料，包括以下步骤：将废旧的混凝土清洗干净并烘干，再对废旧混凝土块进行分级切割粉碎，得到废旧混凝土粉末；将废旧混凝土粉末20‑60份、改性轻质颗粒2‑15份、助剂2‑3份、发泡剂5‑6份加入到水中，并在机械搅拌条件下混合均匀，得到混凝土材料；再将混凝土材料浇注到模具中，在温度为15～25℃，湿度为85～90％的养护室中养护24h得成型试件；将成型试件脱模，在温度为15～25℃，湿度为85～90％的养护室中养护28d，即制成保温隔音轻质发泡混凝土材料成品；本发明降低生产成本，节约资源，提高社会效益，适宜规模化推广应用；具有着良好的韧性、隔音保温性能。
