Working Performance

This paper analyzes the reasons for delamination of ceramsite aggregate concrete mixture, obtained influencing factors of working performance based on the study of equations of lightweight aggregate motion. Moreover, by experimental study of the different pre-wetted time conditions on working performance, a reasonable pre-wetted time of ceramsite before ceramsite aggregate concrete for construction is summarized as well.

Based on the test of 108 blocks with 150mm×150mm×300mm, 54 blocks with 150mm×150mm×150mm, elastic modulus of that of combined aggregate concrete is studied, and the influencing factors on it are discussed. The results show that the elastic modulus of combined aggregate concrete are very much affected by the ratio of common aggregate to lightweight aggregate, and it increases with the water-cement ratio decreasing. The calculation equation of combined concrete modulus is suggested.

Based on the test，the shear behavior of combined aggregate concrete beams is studied. The results show that combined aggregate concrete beam have similar behavior with ordinary concrete beams, and the shear capacity reduces with the increase of lightweight aggregate. And design formula of the combined aggregate concrete shear capacity is suggested.

The Relationship

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.
