This document discusses building stones used for construction. It defines building stones as those suitable for structures like retaining walls, abutments, dams, and roads. Building stones must have strength and durability. Stones are classified as igneous, sedimentary, or metamorphic based on their formation. Common building stones include marble, granite, sandstone, limestone, chalk and laterite. Properties like hardness and durability depend on a stone's mineral composition and resistance to weathering. Stones are obtained from rocks through quarrying and are used in construction in various forms such as rubble, dimension stone, flagstone and crushed stone.

3. STONES
 THE 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.

4. CLASSIFICATION
 IGNEOUE ROCKS
 SEDIMENTORY
 METAMORPHIC

5. TYPES OF STONE
 MARBLE
 GRANITE
 SAND STONE
 LIME STONE
 CHALK
 LATERITE

6. PROPERTIES
 HARDNESS
 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.

7. • 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

8. 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 AND
3. THE METAMORPHIC ROCKS

9. STONE IS USED IN
CONSTRUCTION IN THE
FOLLOWING FORMS :
 RUBBLE
 DIMENSION STONE
 FLAGSTONE
 CRUSHED STONE

10. 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.
