1. INTRODUCTION Concrete being the highest consumed material on earth is produced and used at a large scale in the construction industry. Many innovative techniques and economical methods are being proposed and filler slab technology is one such innovative and cost-effective technology where a dead load of the slab is reduced by replacing the concrete. Concrete is good in withstanding compressive forces and steel is good in withstanding tensile forces. The main aim behind the use of filler-slab technology is to condense a substantial portion of concrete below the neutral axis since all concrete in the tension zone does not add to the tensile properties. This concrete is replaced with lightweight, inert and inexpensive filler without neglecting the quality and structural strength of the structure 1.1 APPLICATION
Figure 1
At st Thomas mount a 300 years old building built by Robert clive which has a single floor area of 8000 sq ft plan shown in fig 1 .It has heritage of an old British gothic architecture .Now cantonment Office is functioning in this building .The portico slab of the building has done at that time by lime mortar based terrace roof .The wooden rafters and purlins got damaged due to natural forces.
