STONES AND BRICKS
BUILDING STONES: Man requires different types of buildings such as houses, bungalows, flats etc for
His living. For his activities man also require Hospitals for his health; Schools, Colleges and Universities
for his education; Banks, Shops, Offices and Factories for doing works; Railway buildings, Bus stations
and Air terminals for his transportation; Clubs and Theatres for recreation and Temples, Mosques,
Churches etc for worship. Each type of the above buildings has its own requirements and needs building
stones to construct the same. The period from 1750 A D onwards is known as
the period of Modern Architecture.
The use of reinforced concrete in construction triggered the rapid development of
modern architecture. Structural components such as Columns, RCC slabs became increasingly popular
because of the increased speed in construction. Use of plywood, glass, decorative materials etc helped the
designers to make the new structures look more elegant in addition to the usage of various building
So, the engineering structures are composed of materials and are known as the engineering materials ( or )
building materials. Hence, Building materials have an important role to play in this modern age of
technology. Building stones are obtained from rocks, are derived into three groups viz., Igneous,
Sedimentary and Metamorphic rocks.
QUARRYING OF STONES: The process of taking out stones from exposed surface of natural rock beds
is known as the quarrying. While selecting a quarry site, one should remember that the availability of
quantity; desired quality, transportation facilities, cheap local labor, and free from the permanent
structures in the vicinity, drainage of rainwater etc..
In case of a quarry, the operations are carried out at ground level (in an exposed condition) whereas in
case of mine, the operations are carried out under the ground at greater depths.
SELECTION OF A SITE FOR QUARRYING:
• Availability of Raw material, Tools, Power, Labor
• Space for dumping of refuse material.
• Distance of quarry from roads, railways.
• Proximity to the transportation facilities.
• Easy availability of clean water in sufficient quantity throughout the year.
• Economy in quarrying
• Blasting material availability
• Absence of permanent structures
• Geological data regarding rock formations.
