The Application of Straw Concrete Wall Board in Constructional Engineering

摘要

Constructional engineering was always faced with the threaten of earthquake and the problem of large energy consumption. As a new type of green building material, straw concrete has better ductility than normal concrete. In the straw concrete multi-ribbed slab structure, as the filling material of wall board, straw concrete improved the energy dissipation and deformability of wall board. When the load was applied, the filling blocks, grid frame and outer frame in straw concrete wall board work cooperatively, have good mechanical properties. The straw concrete wall board has advantages that light, high strength, energy conservation and seismic resistance. Considering the effect of different components in straw concrete wall board, this paper proposes the formula of vertical bearing capacity of straw concrete wall board to provide the basis for engineering application. The construction of straw concrete multi-ribbed slab structure include three processes that steel bar bind, blocks prefabrication and integral pouring, which fits for field fabrication in the building construction site.
