Experimental Study on Concrete Slab Combined with Permanent Cement Formwork with Joints
In this research, a kind of composite cement plates are utilized as permanent formworks, and poured concrete together to form composite slabs. Through static test of composite slabs with different bonding modes of interface between formwork and concrete, bearing capacity, deformability and cooperation states of concrete and composite formwork are studied. Through static test of composite slabs with splicing joints formworks at different positions, bond quality near the splicing joints are observed visually, stress nature and deformability variations resulted from different splicing joint positions of formwork are analyzed. And meanwhile, stress and deformability of the ordinary concrete slab without formwork is researched under the same conditions. Through above experiments, acting as a part of the slab, how composite formwork influence bearing capacity and deformability of the combined slab is investigated.
