Load-bearing and heat-insulating integrated foam concrete and preparation method thereof
The invention belongs to the technical field of building materials. The invention relates to load-bearing and heat-insulating integrated foam concrete. The load-bearing and heat-insulating integratedfoam concrete is prepared from the following components in parts by weight: 400-700 parts of light calcined magnesia, 130-300 parts of bischofite, 0-300 parts of fly ash, 40-50 parts of silica fume, 0-3 parts of polypropylene fiber, 9-10 parts of a high-efficiency water reducing agent, 0-10 parts of citric acid, 3-5 parts of a foaming agent, 0-1 part of a foam stabilizer and 200-400 parts of water. The dry density of the foam concrete is 920-1020kg/m<3>; the compressive strength ranges from 10.4 Mpa to 14.7 Mpa; the thermal conductivity coefficient is 0.141 W/(m.K)-0.153 W/(m.K), the strengthis high, the thermal insulation performance is good, the load-bearing and heat-insulating integrated foam concrete can be used for bearing structures of multi-storey and low-storey buildings, the thermal insulation layer and the building structure can be integrated and have the same service life, the construction cost is reduced, and the load-bearing and heat-insulating integrated foam concrete has wide application prospects in the field of village and town green buildings.
本发明属于建筑材料技术领域，所涉及的承重保温一体化泡沫混凝土，按重量份，由下述组分制得：轻烧氧化镁400～700份，水氯石130～300份，粉煤灰0～300份，硅灰40～50份，聚丙烯纤维0～3份，高效减水剂9～10份，柠檬酸0～10份，发泡剂3～5份，稳泡剂0～1份，水200～400份。该泡沫混凝土的干密度为920～1020kg/m3，抗压强度为10.4～14.7Mpa，导热系数为0.141W/(m·K)～0.153W/(m·K)，强度高，保温性能良好，可用于多层、低层建筑的承重结构，能够实现保温层与建筑结构同体同寿命，降低工程造价，在村镇绿色建筑领域有着广阔的应用前景。
