Abstract:In order to study the flexural behavior of composite B03-grade autoclaved aerated concrete（AAC） slabs, the quarter-point bending experiments of two composite B03-grade AAC slabs and two B03-grade AAC slabs were carried out. The experimental results show that the composite B03-grade AAC slabs have better flexural behavior than that of ordinary B03-grade AAC slabs. The cracking load is increased by about 1-3 times, and the ultimate bearing capacity is increased by about 2 times, and the bending rigidity is increased by 2-2 times before cracking. Based on the general bearing capacity formula for AAC, the crack resistance load and ultimate bearing capacity of composite B03-grade AAC slabs and B03-grade AAC slabs were calculated. Compared with the experimental results, the theoretical calculation results were conservative, indicating that both types of slabs had certain safety reserve. The measured and theoretical values of the cracking load of composite B03-grade AAC slabs can meet the wind-resistant design requirements of the envelope structure of high-rise residential building below 100m in Beijing.

Keywords:autoclaved aerated concrete; composite slab; flexural capacity
