What should be the required steel in column beam and slab?
The required steel in columns, beams, and slabs is determined by structural design calculations that consider factors like load-bearing capacity, span length, and building codes. Typically, columns require higher steel reinforcement due to axial loads, while beams need to resist bending moments. Slabs generally have a lower steel requirement and are reinforced for tensile strength. The specific amount and type of reinforcement, such as rebar sizes and spacing, should be based on detailed engineering analysis and design standards.
Can you lay new paving slabs on top of old ones?
You could, but then you might risk causing damage to the new paving slabs, or exacerbating drainage issues. I would go ahead and remove the old slabs as these are usually just laid in with plain sand between them. Even if it's cement, I'd hate to have to do it over.

How many slabs would you need for a sq meter if flags are 600mm x 600mm?
To determine how many slabs are needed for one square meter, first convert the dimensions of the slabs from millimeters to meters. A 600mm x 600mm slab is 0.6m x 0.6m, which has an area of 0.36 square meters. Therefore, to cover one square meter, you would need approximately 2.78 slabs. Since you can't have a fraction of a slab, you would need 3 slabs to cover one square meter.
