strength of the granite veneer cladding panels and the effect of wetting–drying cycles on the strength. This will lead to better design and less failure incidents. Although granite veneer panels are used as a cladding, and seldom considered as a structural element, being thin panels raise concern over its flexural capacity under wind loading.
Coarse aggregates are boulders, granite chips, natural stones etc. In the process of sieve analysis the material which retains on IS Sieve of 4.75mm are called coarse aggregate. Generally broken hard stone is used as coarse aggregate. The type of work decides the size of aggregates. For example thin slabs require small size coarse aggregates.
and they are more rigid. A porous and cement-rich stone is more durable and can bear the addition strength caused by thermal expansion. Keywords: natural stone, historical monument, fire, heat effect, petrological and petrophysical analyses . 164
