Multifunctional lightweight concrete and preparation method thereof
The invention discloses multifunctional lightweight concrete and a preparation method thereof, and relates to the technical field of building materials. The multifunctional lightweight concretecomprises 92-97% of a component A and 3-8% of a component B, wherein the component A is prepared from 2500 to 3000 parts of cement, 2000 to 2500 parts of quick lime, 100 to 300 parts of gypsum, 4700 to 4900 parts of fly ash, 5 to 15 parts of aluminum powder paste and 4500 to 5500 parts of water, and the component B is prepared from 300 to 700 parts of unfired natural magnesite powder, 50 to 150 parts of expandable graphite and 5 to 10 parts of sodium hydroxide or potassium hydroxide. The lightweight concrete disclosed by the invention can be prevented from collapsing during early-stage maintenance, can absorb heat and reduce the temperature when a fire disaster occurs, can generate a compact result after being heated to increase the strength of the concrete, release flame-retardant gas to reduce the oxygen concentration and prevent fire spreading, and can also adsorb particulate matters to reduce the dense smoke concentration and increase the escape opportunity.
本发明公开了一种多功能轻质混凝土及其制备方法，涉及建筑材料技术领域。本发明包括92%～97%组分A和3%～8%组分B；其中组分A包括2500～3000份水泥、2000～2500份生石灰、100～300份石膏、4700～4900份粉煤灰、5～15份铝粉膏和4500～5500份水；所述组分B包括300～700份未经烧制的天然菱镁矿粉，50～150份可膨胀石墨，5～10份氢氧化钠或氢氧化钾。本发明的轻质混凝土，在前期养护中可防止坍缩，能在发生火灾时吸热，降低温度，受热后生成致密结果增加混凝土强度，释放阻燃气体降低氧气浓度，阻止火势蔓延，还可以吸附颗粒物降低浓烟浓度，增加逃生机会。
