While constructing a building, cement is the
most important ingredient or raw material. Cement is mixed with an appropriate
amount of sand and water to make an aggregate paste which is further used in
making pillars and is even used as a binder in roads, schools, housing dams,
and ports, etc. But before using this mixture or aggregate, it is necessary to
test it with cement testing equipment. You can get assistance and services from
the best cement testing machine
manufacturers who can aid you in the same.
As this aggregate is made up by adding various ingredients and therefore, it
necessitates the testing of end mixture to meet the compliance and
specifications requirements.
Various Cement tests conducted for ensuring
various standards: -
• Compressive strength: For improving the
strength of the building, it is important to check the strength of the raw
material or binder used. The binder includes the mortar and concrete. The
compressive strength of this binder is checked by crushing this binder into a
compressing machine and the strength is determined by the stress or force
applied to crush the mixture.
• Tensile strength: This test is undertaken to
understand the bond between the cement particles. Tensile strength is
proportional and relatively less as compared to compressive strength. It is
simple and less costly. This test is undertaken in a uniaxial tension machine
in which briquettes (made of cement, sand, and mortar) are split and molded.
The tension or load requires to do the same refers to tensile strength. There
are some other methods also to conduct this test if the uniaxial tension
machine is not available.
• Fineness: The fineness of the mixture is
measured by air permeability in the cement particles. Apart from this, the
smaller the particles, the more is the surface area of the powder in terms of
volume as the smallest particles have more ability to contain a large number of
contacts.
• Consistency and setting time: The
consistency test is conducted to check the amount of water required to make a
perfect blend of cement. In this test, it is checked that how much time is
taken by water to set or harden the cement and how much time it takes to harden
after applying on the surface is known ad setting time test. This test is done
with the help of the Vicat needle test in which the needle has penetrated the
cement to check whether the cement has hardened enough or not.
• Soundness: It is an important test and is
done to check the ability of hardened cement paste i.e. whether it has retained
the surface volume after setting or not.
Hence, these are some cement tests which are
required to conduct to ensure that the specifications are complied with. You
can get these tests done through the best cement testing machine
manufacturers. This will improve the workings and strength of the
building. Moreover, it will help you to retain your goodwill as a constructor
or builder and help in cost-cutting as it will ensure less wastage of material
and improve your reasonable time of waiting for the preparation of paste or
mixture.
