This paper aims to point out the use of precast dense concrete rigid pavement slab deck construction using precast\ndense concrete trapezoidal reinforced beams, precast reinforced marble mosaic tiles and plaster of Paris. While application of\nfull-depth precast bridge deck panels may be appealing because of an accelerated construction schedule and improved safety\nconditions, corrosion of steel reinforcement is a major factor affecting the structural durability of precast panels and overall\nserviceability of a bridge deck. Building methodology for low cost housing is highlighted by replacing monolithic slab by hollow\nprecast concrete slab completing RCC slab, flooring and ceiling plaster at time using above mentioned precast members. This\ntechnique not only achieves economy but also saves time of construction if compared with traditional reinforced cast in-situ\nconcrete slab. However present technique is limited to 3.0 m clear span for beams. This slab would also increase sound and heat\ninsulation due to hollow slab. This study reveals that cost of slab construction is reduced by 30%. Further this study can be very\nuseful for mass housing in developing country like India.
