Density Of Fresh And Hardened Concrete
Specification:
The density of both fresh and hardened concrete is of interest to the
engineer for numerous reasons including its effect on durability, Strength
and resistance to permeability.
Hardened concrete density is determined either by simple dimensional
checks, followed by weighing and calculation or by weight in air / water
buoyancy methods.

Compression Testing Machine
Specification:
In these load frames “C” channels are used, they are
welded at the top as well as bottom and with stand high
loads. A hydraulic jack is fitted at centre of the base of
the load frame, over which can be fitted lower platen
and spacer block with the help of centering pin. A lead
screw passes through the top of the frame. To the lower
end of this lead screw is fixed the upper platen with
spherical seat for self alignment. The platens are
accurately machined, hardened and polished. The
lower platen grooves to correctly place the specimen.
Note: The platens are normally rectangular on shape,
but no special request square platens or circular platens
can be supplied at an extra cost.
Ranges: 50 kN to 2000 kN
