Abstract:The paper reports the fundamental performances of light-weight concrete with density of 1.4, based on an experimental study on the properties of composite slabs with trussed steel decks using superlightweight concrete under bending moment. The test results by full scale specimens showed that the composite slab using trussed steel decks and the super-lightweight concrete had the same capacity with the composite slab using normal concrete in strength, deformation, and crack propagation. It was concluded that the calculated values by the conventional theoretical method showed good agreement with the experimental results.

Key Words:super-lightweight concrete, composite slab, trussed steel deck, bending experiment
