What is the difference between Marble and Granite ?



All the site Engineers use to face the same question during the construction phase. Here we will try to give few points of difference between marble and granite. 


Point No. 01 :- 


Granite is a silicious rock which implies that silica predominates in this stone. 
Marble is a Calcareous Rock which implies that Calcium Carbonate predominates in this stone.

Point No. 02 :- 


Granite due to its chemical composition is not affected by the process of weathering.  
Marble however is not that durable. Due to presence of Calcium Carbonate its durability depends on the surrounding environment. For example Taj Mahal in Agra is made up of White Stones which are believed to be deteriorating due to pollution. 

Point No. 03 :- 


Granite is more strong. Compressive strength of Granite varies from 75 N/mm2 to        127 N/mm2. 
Marble is comparatively less stronger. Its compressive strength is around 71 N/mm2. 

Point No. 04 :- 


Carving (नक्कासी ) is difficult in case of granite and the reason can be better understand in relation with the Point No. 03 Above. 
Carving is easy in case of Marble.  Probably this is the reason of choosing Marble in Historic Structures. 

Point No. 05 :- 


in Terms of Origin, Granite is an Igneous Rock. 

Marble is a Metamorphic Rock.

Point No 06 :- 


In General, Granite is more costly compared to Marble. 



These are the basic differences between Granite and Marble.
