Hello XXXXXXXXX,

Welcome to Just Answer.

 

There is not a straight answer for this question, because there are alot of variables that make up the load bearing capacity of concrete. Concrete by itself comes in different compressive strengths. Regular concrete can range from 1450 psi to 5800 psi. High strength concrete is generally higher than 6000 psi. Concrete is great at compressive loads but not tensile. Steel reinforcing is used to compensate for this. There are many forms of reinforcing and this affects overall load capacity as well. Column and beam spacing also affects load capacities. You really need to know all of this to determine the load capacity of the slab. A structural engineer can help determine what these variables are.
