Abstract
Systematic research is being carried out since last more than one decade to prove the validity, method and materials for construction of locally available alternatives as low-cast systems for the sake of swift erection of buildings at relatively affordable cast of construction, where the pre-cast post-reinforced panels are used for erection of buildings without sacrificing the strength and durability of the buildings. One of the most universally available materials of construction since immemorial times is the earth itself, particularly in the plain areas (Pakistan) where the soil is fertile and the availability of best combination of clay and sand is not problematic. In this paper the authors present the details of systematic research which has been carried out to prove that if pre-perforated post-reinforced baked clay beams are employed for pre-cast construction, the economy could be achieved by up to 30 % without sacrificing strength, durability and stability of construction. Initially soil was dug from 25 sites at a depth of 4 ft. Their physical properties were determined. The presence of various salts and their proportion were also found. A very large number of cubes were cast with clay as major material and percentage of pit-sand (silica) as major parameter. The results of preliminary study in terms of shrinkage, specific gravity, crushing strength, tensile strength, poison’s ratio, and modulus of elasticity of baked clay specimen and the best possible combination of clay and pit-sand were obtained. The material was then compacted by applying compression. Fifty two beams with 70% clay and 30% pit-sand, 20 percent water and 4.5 N/mm2 compacting force were cast, dried, baked, post-reinforced, grouted with cement and hill-sand slurry with the ratio of 1:1 for proper bond between steel bars and surrounding baked clay were tested with point load, UDL and various boundary conditions including roller support, plate support and complete end-fixity. Full details are presented in the following section.
