Experimental study of cold – Bonded artificial lightweight aggregate concrete

At present, there are much more researches on the ordinary concrete composite slab, and that on the lightweight aggregate concrete composite slab are relatively less. In this paper, the shear-bond behavior of lightweight aggregate concrete composite slab, with the profiled steel sheet YX-76-344-688, which is commonly used in China is studied. Base on experiments, the cracks developing process and its regularities of distribution, the bonding and slipping between profiled sheeting and concrete, the relationship of load and mid-span deflection, ultimate bearing capacity etc. are studied.

Load Bearing

A kind of lightweight sand was only used as the fine aggregate to make the all-lightweight aggregate concrete, which can significantly reduce the gravity load of a structure and the foundation loads. Accordingly, the application of all-lightweight aggregate concrete in the construction projects can reduce the cost of foundation as well as construction project. In order to develop a new multi-story structural system which has a multifunction of load-bearing, lightweight and energy saving, the paper carried out an experimental study on the mechanical behaviors of six all-lightweight aggregate concrete columns with symmetrical reinforcement under eccentric loading. The failure modes, deformation characteristics and load-bearing capacity of the columns were analyzed. The effect of reinforcement ratio, stirrup ratio and eccentricity on the mechanical behaviors of the columns under eccentric loading were discussed. The test results show that all-lightweight aggregate concrete columns were loaded to failure with high load-bearing capacity and good ductility. The excellent mechanical behavior and the possibility of replacing the normal concrete with all-lightweight aggregate concrete were verified.
