摘要

Reinforced cement concrete found wide acceptability all over the world during pastmore than hundred years as major material of construction. But due to escalation of cost ofsteel and cement and particularly the transportation charges for bringing these materials ofconstruction to the sites in the distant areas where the soil is clayey in nature (in the plains),it could be more beneficial and economical to produce baked clay panels of structuralmembers for swift and economical construction without sacrificing the strength anddurability of the buildings. Visualizing the future construction in the rural areas at relativelycheap and affordable prices, a large number of beam panels were cast, baked, postreinforced, cured and tested. The results of that experimental study have been presented inthis paper. In order to determine the shear/flexural strength of baked clay alone no verticalreinforcement or anchorage steel was provided. The study was carried out in terms ofmodulus of rupture, shear/ flexural behaviour, mode of failure, crack pattern and ultimateload of baked clay beams. However, fundamental structural properties and materialconstants i.e. crushing strength, Poisson's ratio and modulus of elasticity of the material cutfrom the beams after testing them, were also determined experimentally. The results areencouraging. However, from these tests it is found that shear strength is the dominant factor.Complete details are given in the following sections.
