Abstract

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.
