Engineers will consider the forces involved on the concrete slab and come up with a figure of -ve and +ve rebar needed to resist the moments. They will also consider the strength of concrete required, 20mpa, 32 mpa etc. Sometimes temperature steel is also added.
They will usually come up with a figure like 575mm/m2 of rebar needed in the +ve and another figure for the -ve. Then the designer steps in, looks up their rebar tables and works out that to cover 575mm/m2 they can use 4-N20-LL-320 or something. Which stands for 4 size n20 (20 dia) bars, LL shape, so a 90 bend on both ends, at 320 spacing.

What are the different types of concrete slabs?
Different types of Slabs :1. Conventional solid slab:-- the slab which is braced with beams and columns is called conventional slab this kind of slab is small whereas the depth of the beam is large and load is transferred to beams and from beams to columns. These types of slabs are used in constructing Floors of multi stored building. It is of two types.a) One-way Slab.b) Two Way Slab.2. Flat Slab:-Flat slab is a reinforced concrete slab secured directly by concrete columns or caps .flat slab doesn’t have beams.3. Waffle slab:- Waffle slab is a reinforced concrete roof or floor containing square grids with deep sides. This kind of slab is majorly used at entrance hotels, malls, restaurants
What is Limit state design in reinforced concrete design?
Limit state design is designed a concrete member for its various damage limit states, concrete sover spalling, steel yielding all the way up to the crushing of the concrete core, with this you can control how you want the concrete member to fail.
What is a floating slab foundation?
Floating slab is a type of mat foundation. It consists of a hollow mat formed by a grid of thick reinforced concrete walls between two thick reinforced concrete slabs. The weight of the soil excavated from the ground is equal to the weight of the entire building, so that pressure on the soil is unchanged from the original condition, making the building float on the soil
What is two way slab?
Two-way slabs are rectangular reinforced-concrete slabs that are supported on all sides. The reinforcement is placed perpendicular to the sides.
What is the meaning of the solid slab?
A solid slab is a reinforced concrete slab which is supported by beams or walls..

What are the recommended footings for a concrete slab?
The recommended footings for a concrete slab are typically made of reinforced concrete and should be at least 6 inches thick and extend below the frost line in your area to prevent shifting or cracking.

Can cinder be used in the sunken parts of a reinforced cement concrete slab?
Some contractors recommend and use cinder in the sunken parts of a reinforced cement concrete slab. Others caution against it in construction where a lot of seepage can occur because cinder can have a tendency to retain the water.

Why it is called a biaxial voided slab?
Voided biaxial slabs are reinforced concrete slabs in which voids reduce the amount of concrete.While concrete has been used for thousands of years, the use of reinforced concrete is a relatively recent invention, usually attributed to Joseph-Louis Lambot in 1848. Joseph Monier, a French gardener, patented a design for reinforced garden tubs in 1868, and later patented reinforced concrete beams and posts for railway and road guardrails.The main obstacle with concrete constructions, in case of horizontal slabs, is the high weight, which limits the span. For this reason major developments of reinforced concrete have focused on enhancing the span, either by reducing the weight or overcoming concrete's natural weakness in tension
