Some required points to improve the quality
of Concrete for stronger & durable Construction,
Constituent of Concrete
Basically the main ingredients of concrete are
A) Cement b) Water C) Stone d) Sand
Qualities of material are very important
for good Concreting.
Compaction of Concrete.
When concrete is placed, the air is trapped inside the
concrete. If air is not removed, the air void will weaken
the concrete. The voids can lead to the reduction of bond
between concrete and reinforcement. It is also the cause
As a Result of improper compaction of concrete,
approximately 35% of strength is lost.
Curing of Concrete
Curing is the process in which the concrete is protected
from loss of moisture and kept within a reasonable
temperature range. It should remain protected for
sufficient time to become strong and durable.
If it is not cured within the first 7 days, the concrete will
lose almost 66% of strength.
Preparation of concrete
M-20 Grade of concrete is suitable for RCC construction.
(1:1.5:3)Water should be used as per requirement.
Excess water should not be used to make the mix more
Brick and block masonry
The building material brick is used to make walls,
pavements and other elements in masonry construction.
Brick is referred to a unit composed of clay, but it is now
used to denote any rectangular units laid in mortar.
Block is similar to a rectangular building unit composed
of materials, but is usually larger than a brick.
The Lightweight bricks are also called lightweight blocks.
It is made from expanded clay & aggregate
Mortar is a mixture of sand, cement and water that is most
often used to build brick, block walls and plaster.
RCC (Reinforcement Concrete Construction)
RCC is Reinforced Cement Concrete in which the structures
are reinforced with steel. The steel takes tension and
the concrete takes the compression. It is the most widely
used construction process, where the improper quality
of concrete & concrete cover is the major cause of distress
