It provides a simple and attractive alternative to RCC construction for small to medium spans. These can be used to span square, rectangular or even triangular and nonorthogonal spaces and consist of thin sheet concrete, brick, stones, tiles supported on edge beams. These are cost effective as the required quantity of steel and cement is much less and can be precast avoiding costly shuttering.
