Cast

Hi.
What are cast and precast floors?
When comparing the construction related impact of in situ cast ?oors with precast ?oors, the smallest precast hollow core slabs on the market performed much better than a normally dimensioned in situ cast ?oor regarding structural strength.

Thanks in advance

Assume you want a concrete floor. If you pour liquid concrete everywhere amd let it set, you have 'cast' the floor. But now suppose that someone in a factory makes (casts) smaller slabs of concrete.

Yes. Cast before you bought it and used it to make your floor.
