The cost of materials and of workmanship have gone so high that it has become almost impossible for a man of modest means to build a house for himself. A major chunk of the total cost of a house is taken up by the roof or floor slab construction. So in order to achieve reduction in cost of buildings, ways and means have to be found to introduce new construction concepts and materials into the building trade. Reinforced brickwork slabs have long been used in place of normal reinforced concrete slabs in our country and are still popular everywhere except in areas where the bye-laws forbid their use. It is generally considered that R. B. Slabs are a cheaper substitute for normal R. C. C. Slabs. But unfortunately the construction is based on the thumb rules and previous similar experience alone, no rational design method is available, and for this very reason, certain bye-laws do not permit their use. Described in this paper are the results of test on a slab panel, fabricated in an unconventional manner using broken brick bats as filler material in slab.
