concrete fill over metal deck
concrete fill over metal deck
(OP)
I have a building from the early 60's that has steel joist with metal form deck covered in a light weight concrete used for roof slope with the consistency of masonry grout. In looking at the available capacity of the joist, the current system seems to be overloading the joist capacity. I think that the concrete fill is probably not the 110 pcf that I am assuming. Has anyone had experience with these types of concrete deck fills and if so, what concrete density have you used?

It should be specified on the drawings or the spec. If no data is available, you may have to take several cores to verify.

Get the volume using a container of known volume of water and measuring the amount displaced by sample.
It's pretty risky to make an assumption.
