USES OF STONE:Broken stone and stone chips are used in foundation,roofs
and floors of buliding and as rod metal and railway ballast.
Stone block are mainly used in walls , foundation and
ornamental facia work.
Quartzite is used for rubber masonry ,rod metalling and
also as aggregate for construction .
Lime stone slabs are used for flooring ,paving and roofing.
Slates are used as roofing and flooring material.
Marble is extremely suitable for ornament and superior
type of building work .eg.Taj - Mahal
6. Types of bricks
:- Bricks can be classified into two
type:
Type’s of bricks
:-Conventional Brick :- Standared Brick
(23×11.4×7.5cm)
(19×9×9cm)
New genration advanced bricks
Zik – Zak brick
Diamond
Cement brick’s etc.
7. Tiles :
Tile material or its products are divided into the following tree categories
:- 1) Clay products
2) Terra – cotta
3) Earthenware
Properties of tiles :
Tiles materials has the following propertise:-
1)Mechanical properties
Tile material tends to fracture before any plastic deformation
take place which shows poor toughness in the material .
Tensile strength is less .
It deformation very slowly .
2)Electrical properties
Tiles material are semi – conductors and hence employed as a
gas sensors .
At extremely low temperature ,some tiles exhibit high
temperature superconductivity.
It also possesses positive thermal coefficient.
8. Cement
The word cement means a substance which
acts as a bonding agent for materials.
It is defined as finely ground mixture of
calcium aluminate and silicates of varying
composition which composition which
hydrates when mixed with water to form
rigid continuous structure with a good
compressive stength
It designates a fine grey powder that is used
for constructional purpose.
It is manufacturing by John Smeaton
in1756.
9. Classification (type’s) of cements
Cement , generally can be classified into the following classes
Natural cement
Pozzalonic cement
High alumina cement
Portland cement
*Ordinary portland cement
Cement
*Rapid hardening portland cement
*Extra-rapid hardening portland cement
*White portland cement
*Coloured portland cement
*Low heat portland cement
*Portland blast furnace cement
*Sulphate resisting portland cement
Super sulphate cemenet
Special sulphate cement
10. Glass claddings
Now a days ,the glass cladding work is preferably adopted
in building construction ,since it fulfils the various functional
requirement of building such as lighting ,heat retention etc. with
visual impact creation .
It
is totally safe
It is aesthetical and recyclable
It is energy saver and time saver as per the
construction aspect is concerned.
There is no flows of plaster and paint
It has attractive colours
11. Advantages of glass cladding
Use
of glass in construction work adds beauty to the building
Its use fulfils the architectural view for the external decoration
and beauty
Glass is bad conductor of heat, hence it saves energy in air
conditioning of building.
Glass cladding use appear a sense of openness and harmonious.
Disadvantage of glass cladding
It is very costly and may increase the budgeted cost of
construction work.
Use of glass also enhanceds the cost of security .
Its use in hilly area and desert may cause more maintenance.
It is also unsafe for earthquake proven area
