Abstract

The construction of bungalow houses requires sufficient space to accommodate all the requirements as per the client’s wish. The idea of low-rise or high rise buildings is very remote for most of the people due to the high costs of construction involved. Much of the said cost is due to the concrete floor slab as it consumes a bigger portion of concrete material when compared to beams and columns. In this paper, a study presented is on a new form of voided slab constructed from masonry slab elements that do not utilize formwork and consumes less concrete material. The slab is composed of slab strips made from masonry slab elements, which are prepared on ground and after developing sufficient strength are then manually lifted and placed in position of the slab. It has been observed that the strength of the hollow slab is equal to the solid concrete slab, and the associated cost of this new type of slab is only 60% of the solo solid concrete slab. Hence, low-rise building can be constructed at low cost with advantages of saving space and positive environmental effect as less or no trees are felled for shuttering purposes.
