swampy water feature, what would be the type
of slab system you proposa?
a) Ground supported slab
b) Basement floor slab
(C) Ground suspended slab
d) Ribbed slab



Answer :

Final answer:

Finely graded aggregate needs more paste, chemical admixture is used in smaller amounts, and ribbed slab is suitable for sites with specific features.


Explanation:

Finely graded aggregate requires more paste because it has a larger surface area that needs to be covered by the paste to achieve proper cohesion in concrete.

Chemical admixture is used in smaller amounts compared to other types as it is highly potent and effective in altering the properties of concrete.

Among the choices provided, ribbon slab would be a suitable slab system for a site with sloppy topography and swampy water features, as it can provide better support and stability in such conditions.
