lightweight concrete over metal decking
the decking rests over the structural steel floor beams network which is erected using suitable means. this decking not only acts as permanent formwork to the concrete but also provides sufficient shear bond with the concrete so that the two materials act compositely together.
what you should know about your cement roof deck
when structural lightweight concrete is then poured the aggregate voids are loaded with water. if a roof is installed over the top surface and the deck was cast into non-vented metal form deck the logical conclusion is that the dry down mechanism is at best severely retarded.
design of composite steel deck floors for fire
assessment of composite steel deck floors with mesh reinforcement. composite steel deck floors consist of a profiled steel deck with a concrete topping. included in the concrete is some light welded mesh reinforcement which acts to control cracking to resist longitudinal shear and in the of fire to act as tensile reinforcement.
finishing lightweight concrete on elevated decks concrete
we have installed hundreds of thousands of square feet of suspended floor slab on metal decking using lightweight concrete and we've found it's next to impossible to get a smooth level floor. all our work is done with power trowels and when the slab is at its optimum for finishing the concrete
elevated concrete deck
re: elevated concrete deck i did a concrete deck over a 2 car garage last summer. it had a steel i beam down the center with 2x framing. the speced 3/4 ply waterproof membrane and then 4" of concrete. don't use the ply. go steel decking and save yourself many many issues. oh and i would want it engineered way to risky to wing it.

in most cases the higher cost of the light-weight concrete is offset by a reduction of structural elements less reinforcing steel and reduced volume of concrete. in buildings light-weight concrete will produce a higher fire rated structure. it also provides higher r-values of wall elements for improved insulation properties.
