6 Stone

7 Requirements of stone 1)Structure: they may be crystalline or amorphous. Unstratified rocks are good as building stones. 2) Appearance-colour texture: stones of light shades may be preferred to dark coloured stones. Red and brown coloured. 3)weight: light weight stones are preferred for domes and arches. 4) Fitness of grains : non- crystalline stones are difficult to handle and liable to be disigntegrated. 5) durability: stone must have the property to resist loads, chemical action of atmosphere,rain,water,snow etc.

8 Types of stone: The stones are obtained from various rocks. The types of rocks are as below. Rocks may be classified on the basis of geological formation are types of stones Igneous rocks Sedimentary rocks Metamorphic rocks

9 Uses of stones  In foundations, walls, columns, arches, blocks etc.  In hydraulic structures like dams and bridges.  In retaining wall masonry to retain soil.  As ballast for permanent way in railways.  To make concrete in the form of coarse aggregate.
