The slabs that are supported only at end are called simply supported slabs i.e. there is no intermediate supports in the slab and there will be no support moment acting on the slab.
1. one way slab 2. two way slab 3. flat slab 4. roof slab
The purpose of a keyway is to stop the movement of the foundation.
Grade beams works as frame and take the load of slab and diverse to the ground
The answer will depend on 4 inch slab of what material!
According to the Amlink material weight calculator, a slab of marble of this size would weigh 4200 pounds. If using this for a countertop, make sure that the support is strong enough to distribute the weight properly.
2500N/m3
A standard paving slab will weigh approximately 70KG, which is about 154 pounds. Of course, it varies in weight according to the actual size of the slab, but that is what the average standard slab will weigh.

Slab on grade
to answer your question, one must know the thickness of the slab? then only the weight can be calculated
m20 grade concrete per m3 load
Slab 15mm
45kg
In laymen's terms, yes. Many people use the terms Slab-on-grade & Floating Slab interchangeably. However, architects, engineers, and construction workers may have a more refined interpretation. Most commonly, a Slab-on-grade construction refers to a foundation in which the a concrete slab (also most commonly thickened at the perimeter) rest directly on grade (aka ground). Where as a Floating Slab foundation refers to a concrete slab resting directly on the grade independently placed within a stem wall (aka foundation wall), which extends down to the depth of the local frost line, running around the entire perimeter. The walls of the building/structure are then built upon this "stem wall". This latter type of construction creates a 'heat bubble' so that the floor is not as subject to the expansion due to frost and secures the structures walls by being supported below the frost line.
