Introduction1) Naturally available material - Clay /earth/soil -Wood/Timber -Sand/Fine aggregate -Rock 2) Artificial materials cement , brick , steel, tiles , ceramic , paints and varnishes glass , plastic , stone , lime.Properties of materialToughnessStrengthCompressive strength it is a mechanical property of material. The ability of a material to withstand stress due to compressive forces on it, without fracture is called compressive strength

Stone

StoneRequirements of stone1)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.

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

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.

Properties of stonesHard and durableMarble and quartzite have compact crystalline structure.Acid resistanceCompressive strength.Importance of stones. In masonry In wall In natural beds with horizontal direction.

Bricks

Brick Bricks are rectangular blocks made from clay.

Composition of brick:

The clay should be free from pebbles, gravel, alkalies, organic matter, vegetation and iron pyrites.
