    摘要
  • 摘要: 为解决国内外保温墙体易发生火灾、保温层材料不环保等问题,设计了一种由纤维增强碱矿渣胶凝材料为页墙、秸秆板为夹芯层的新型复合墙体,并测试了新型夹芯板的力学性能和热工性能。试验结果表明:在力学性能方面,夹芯板在轴心荷载作用下发生劈裂破坏,适量的连接件可有效提升夹芯板的承载力,钢丝网片对夹芯板的承载力提升不明显,并提出了新型夹芯板的承载力计算式;在热工性能方面,新型夹芯板的导热系数为0.21 W/(m·K),低于混凝土(1.28 W/(m·K))和建筑砖(0.69 W/(m·K))的导热系数。碱矿渣胶凝材料作为低碳固废胶凝材料,有望替代传统水泥基材料,其夹芯板具有优良的力学性能和良好的保温隔热性能。
    Abstract: In order to solve the problems of fire-prone insulation walls and environmentally-unfriendly insulation layer materials at home and abroad, the paper designed a new composite wall made of fiber-reinforced alkali slag cementitious material as the page wall and straw board as the sandwich layer, and tested the mechanical and thermal properties of the new sandwich panel. The test results showed that: in terms of mechanical properties, the sandwich panel split and broke under the action of the axial load, the appropriate amount of connectors could effectively improve the bearing capacity of the sandwich panel, the wire mesh did not significantly improve the bearing capacity of the sandwich panel, and the formula for calculating the bearing capacity of the new sandwich panel was proposed. In terms of thermal performance, the thermal conductivity of the new sandwich panel was 0.21 W/(m·K), which was lower than that of concrete (1.28 W/(m·K)) and building brick (0.69 W/(m·K)). In summary, it can be seen that alkali slag cementitious material is a low-carbon solid waste cementitious material, which is expected to replace traditional cement-based materials. Its sandwich panel has excellent mechanical properties and good thermal insulation performance.
