QUESTION NO 01
Define
soundness of concrete?
This test is done to
find out the change in volume of cement paste after it is set. The change in the
volume of the cement paste may be due to its late set or the presence of
unobtrusive free lime or other components in the joint.
QUESTION NO 02
Define concrete mix design?
Proposing a ratio for
concrete components that maximizes the required strength using minimal cement
is called design in concrete. It seeks to make heavier concrete, taking into
account the medical properties of the concrete components.
QUESTION NO 03
Enlist Non-destructive test
of concrete?
·
Rebound hammer test
·
Penetration resistance test
·
Break off test
QUESTION NO 04
Define workability of
concrete?
Concrete workability
refers to a feature of concrete in which it can be easily felt without gaps
during mixing, placing, compaction and finishing. It is also called consistency
of concrete.
QUESTION NO 05
Define Creep of Concrete?
A permanent strain
caused by load acting on a concrete structure is called a creep of concrete. The
elastic strain is formed immediately after the loading process on a stretcher,
while the creep begins to form.
QUESTION NO 06
Define admixture used in
concrete?
In addition to its
essential components in the preparation of concrete, additional components
added to the concrete to create specific qualities are called admixture. They
are sometimes called additives of concrete.
QUESTION NO 07
Define freezing and thawing of concrete?
In cold weather, when
the temperature is less than 5 degrees, pouring concrete freezes the concrete. Therefore
the work of pouring concrete should be up to 5 to 13 degrees. The loss of
volume after the concrete freezes in cold weather and the germination of
concrete at higher temperatures is called freezing and thawing of concrete.
QUESTION NO 08
Define deformed Steel bar?
The steel surface is
designed and roughened to strengthen the bound between steel and concrete and
to achieve some other qualities. Bangles are made on it. Such steel is called deformed Steel bar.
QUESTION NO 09
Define prestressing of
concrete?
The process of creating
an anti-strain of the expected stresses from RCC members and designing them is
called prestressing of concrete . This
reduces the size of the structure, which results in significant savings and
makes the structure more secure.
QUESTION NO 10
Enlist the advantages of
prestressing of concrete?
·
The prestressing process can harness the
extreme strength of concrete and steel.
·
The total area of the structure is used
under pressure due to prestressing. While in the simplest way only part of it
is used.
·
Steel is usually used diagonally in
members made in this way. This way there is no need to use separate steel to
bear the share.
·
Structures made in this way are thinner
with less material used in the construction of these members.
