History of construction
● The history of
construction is a
history of building
materials, the history of
engineering, the history
of building techniques,
economic and social
history of builders and
workmen, the history of
and temporary works etc
History of construction
Each of these has a complex literature devoted to it,
but it perhaps worth providing the briefest of
summaries here in the hope that others will start new
more detailed pages.
● Stone is a natural material we extract from quarries.
● Stone walls are a kind of masonry construction which
have been made for thousands of years. First they were
constructed by farmers and primitive people by piling
loose field stones in what is called a dry stone wall,
then later with the use of mortar and plaster especially
in the construction of city walls, castles, and other
fortifications prior to and during the Middle Ages.
● In the most
general sense of
the word, a
cement is a

● Cement is a construction material , a mix of pulverized
natural soil with small amount of portland cement and
water, usually processed in a tumble, compacted to high
density. Hard, semi-rigid durable material is formed by
hydration of the cement particles.
● Soil cement is frequently used as a construction material
for pipe bedding, slope protection, and road construction
as a subbase layer reinforcing and protecting the
subgrade. It has good compressive and shear strength,
but is brittle and has low tensile strength, so it is prone
to forming cracks.
● Concrete is a composite
construction material composed
of cement (commonly Portland
cement) and other cementitious
materials such as fly ash and
slag cement, aggregate
(generally a coarse aggregate
made of gravels or crushed
rocks such as limestone, or
granite, plus a fine aggregate
such as sand), water, and
● Concrete solidifies and hardens after mixing with
water and placement due to a chemical process
known as hydration. The water reacts with the
cement, which bonds the other components
together, eventually creating a robust stone-like
material. Concrete is used to make pavements,
pipe, architectural structures, foundations,
motorways/roads, bridges/overpasses, parking
structures, brick/block walls and footings for
gates, fences and poles.
● Plaster is a soft solid , that we
normally use for aesthetic
purposes, to cover brick walls
wich have a rough surface
● Plaster comes from gypsum.
We extract gypsum from the
quarry , and then grind it.
When ground gypsum is
mixed with water, it becomes
a paste and we can spread it
on interior walls .
● Advantages :
● Gives a smooth surface
and has a nice finish.
● It's easy to work with.
● It's a good sound and
● It's resitant to fire.
● It's weak.
● It absorbs water.
● Itś the oldest artificial
● Firstly it was used for pottery,
but now we use it in
construction, for example, for
making bricks to make walls.
● Bricks have the advantadge
of beign cheap and durable,
and they require very little
A ceramic is an inorganic, non-metallic solid
prepared by the action of heat and subsequent
cooling. Ceramic materials may have a crystalline or
partly crystalline structure, or may be amorphous .
Because most common ceramics are crystalline, the
definition of ceramic is often restricted to inorganic
crystalline materials, as opposed to the non-
Types of construction
● In general, there are three types of
● 1. Building construction
● 2. Heavy / civil construction
● 3. Industrial construction
● Each type of construction project
requires a unique team to plan,
design, construct, and maintain the
Building construction phases
In the fields of architecture and civil engineering,
construction is a process that consists of the
building or assembling of infrastructure. Far from
being a single activity, large scale construction is a
feat of human multitasking. Normally, the job is
managed by a project manager, and supervised by
a construction manager, design engineer,
construction engineer or project architect.
Building construction phases
For the successful execution of a project, effective
planning is essential. Those involved with the
design and execution of the infrastructure in
question must consider the environmental impact of
the job, the successful scheduling, budgeting,
construction site safety, availability of building
materials, logistics, inconvenience to the public
caused by construction delays, and bidding, etc.

● The general contractor or the mason contractor
pours the footings. In heavy populated areas your
footing contractor may be a subcontractor for the
foundation wall contractor.

foundation and poured concrete foundation walls.
Your concrete floor is commonly poured after the
forms are stripped for the foundation walls.
Phases 10 and 11

the floor joists and apply decking
material to the floor joists.
