Overview
PAC Floor and Roof Slabs are lightweight, fire resistant, fast and easy to install and provide lifelong superior thermal insulation. PAC Slabs are steel reinforced (Grade 70) Autoclaved Aerated Concrete elements. The interior steel wire reinforcement is covered with an anti-corrosion coating. PAC Slab Panel is produced in an ASTM C 1452 strength class: AAC-6. PAC Slabs are produced with 20 cm or 25 cm thickness with a maximum span of 6 meters. In case of longer spans more than 6 meters, a steel beam will be added as a support for the slabs which can be inserted inside the beam. With 20 cm slab thickness, IPE 220 beam is used and in case of 25 cm thickness, IPE 270 beam is used. PAC slabs has a special profile groove of 5 cm on top edge where a steel rebar 12 mm is inserted between the slabs and grouted with none shrinkage grout. In these case, structural screed of 5 cm on top will not be needed.
