The weight a 4-inch slab on grade can support depends on several factors, including the concrete mix, soil conditions, and reinforcement. Generally, a well-designed 4-inch concrete slab can support around 2,500 to 3,000 pounds per square foot. However, for specific applications, it’s important to consult structural engineers or guidelines based on local building codes to ensure adequate support and safety.
To determine the weight a 28 square meter slab of concrete at 100 mm thick can support, we first need to calculate its volume and then its weight. The volume is 28 m² x 0.1 m = 2.8 m³. Given that the density of concrete is approximately 2,400 kg/m³, the slab weighs around 6,720 kg (2.8 m³ x 2,400 kg/m³). The weight the slab can support will depend on factors like the slab's reinforcement and the load distribution, but in general, it can support much more than its own weight.
When constructing a building, concrete for the beams is typically placed first before the slab. This is because beams provide the structural support for the slab, and the slab is often poured to rest on these beams. Pouring the beams first ensures they are properly integrated into the overall structure and can support the weight of the slab and any loads it will carry.

A 6-inch concrete slab can typically support around 150 pounds per square foot.
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.

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.
