Rock Products and Uses - Limestone.
The Manufacture and Uses
of Cement, Mortar, Concrete and Glass.
How is Cement Made and Used?
Powdered limestone is mixed with powdered
powdered clay
and heated in a rotary
kiln to produce cement.
Cement is a
fine
gray powder which is used to
make mortar and concrete.
How is Mortar Made and Used?
Mortar is made by mixing
cement (see above) with lime,
sand and water.
Mortar is used in between bricks or
stones for
building walls, or as a covering surface for
walls.
How is Concrete Made and Used?
Concrete is made by mixing
cement (see above) with
sand, water and
rock pieces.
The rock pieces (called aggregate) may be of various
sizes.
Concrete sets like
stone, and is widely used as a
building
material.
Concrete can be reinforced
with steel rods or
cables, making the material stronger.
How is Glass Made?
Glass
is made by heating together a mixture of
limestone,
sand and
sodium carbonate.
A chemical
reaction happens to produce glass
which is a mixture of calcium
silicate and sodium silicate.
