STONESTHE STONES WHICH ARE SUITABLE FOR

THE CONSTRUCTION OF THE STRUCTURES SUCH AS RETAINING WALLS, ABUTMENT, DAMS, BARRAGES, ROADS ETC ARE KNOWN AS BUILDING STONES.

BUILDING STONES SHOULD POSSESS ENOUGH STRENGTH AND DURABILITY.

STONES HAVE BEEN CONSIDERED AS ONE OF THE POPULAR BUILDING MATERIAL FROM THE OLDEN DAYS DUE TO THEIR AVAILABILITY IN ABUNDANCE FROM THE NATURAL ROCKS.

CLASSIFICATIONIGNEOUE ROCKS SEDIMENTORYMETAMORPHIC

TYPES OF STONE MARBLE GRANITE SAND STONE LIME STONE CHALK LATERITE

PROPERTIESHARDNESS HARDNESS DENOTES SEVERAL QUALITIES OF

STONES SUCH AS RESISTANCE TO CUTTING AND RESISTANCE TO ABRASION ( RUB WITH EACH OTHER ).

SPECIALLY STONES ARE USED IN CASE OF ROADS AND RAILWAY TRACKS.

TO CHECK THE HARDNESS OF STONES VARIOUS TESTS ARE CONDUCTED IN THE LABORATORIES.

THE MORE IMPORTANT TESTS TO CHECK THE HARDNESS IS LOSS ANGLES ABRASION TEST.

IT DEPENDS UPON THE NATURE OF ITS CONSTITUENT MINERALS.

• DURABILITY DURABILITY IS THE POWER OF STONE TO

RESIST ATMOSPHERIC AND OTHER EXTERNAL EFFECTS.

IT DEPENDS UPON : CHEMICAL COMPOSITION, PHYSICAL STRUCTURE, RESISTANCE TO WEATHERIMG EFFECTD, PLACE WHERE IT IS USED STONE WHICH CONTAIN SILICATES WILL

BE DURABLE THAN THOSE STONE WHICH CONTAIN CALCAREOUS SUBSTANCES

STONE AND ITS MAJOR TYPES BASED ON FORMATION BUILDING STONE IS A NATURAL ENGINEERING

MATERIAL. STONE IS OBTAINED FROM ROCK BY APPLYING

CERTAIN DISINTEGRATION TECHNIQUES LIKE MANUAL QUARRYING AND BLASTING ETC.

STONES OBTAINED FROM ROCKS ARE IRREGULAR IN SHAPE AND SIZE AND THUS NEED PROPER DRESSING BEFORE USING FOR CONSTRUCTION PURPOSE.

BASED ON FORMATIOM OF THE PARENT ROCK IT HAS THREE TYPES

1. THE IGNEOUS ROCKS 2. THE SEDIMENTARY ROCKS AND3. THE METAMORPHIC ROCKS

STONE IS USED IN CONSTRUCTION IN THE FOLLOWING FORMS :RUBBLEDIMENSION STONEFLAGSTONECRUSHED STONE

COMMON USES OF BUILDING STONE : IT IS USED IN FOUNDATIONS OF BUILDINGS’ IT IS USED IN CONSTRUCTION OF DAMS, BARRAGES, ETC, IN ITS CRUSHED (POWDERED FORM) IT IS USED AS

ARTIFICIAL SAND, IT IS USED AS RAW MATERIAL FOR MANUFACTURING OF

CEMENT, IN ITS BROKEN FORM IT IS USED AS MATERIAL FOR

CONSTRUCTION OF ROAD AND RAILWAY TRACKS, IT IS ALSO USED AS PART S OF BUILDING SUCH AS

LINTELS AND ARCHES, ETC. IT IS ALSO USED AS THIN SLABS FOR BUILDING ROOFING IT IS ALSO USED FOR ORANAMENTAL WORKS IN

BUILDINGS, IN ITS BROKEN FORM IT IS THE MANUFACTURING OF

CONCRETE.
