Brick factories are fully automated these days.

Bricks are mixed, dried, cooled, and packed in

these factories by various machines rather than

by humans.

Modern brick factory
Cement and Concrete

Cement is a finely ground powder. It is made by

crushing natural minerals like limestone, clay, and

gypsum into powder. Cement forms a highly hard Cement

material and binds the bricks very tightly when

combined with water and sand.

Concrete is a blend of sand, cement, and crushed

stone particles. Concrete hardens and becomes

strong as it sets. Floors, roofs, roads and footpaths
Concrete
are all made of concrete.
Did You
Know? Recycled plastic waste can be moulded into bricks or pavement blocks for use in the
construction of pedestrian walkways, roadsides, or even roads. As these blocks are
lightweight and strong, they provide an environmentally friendly alternative to standard
materials.

Building houses and the people who build them

We might have seen many buildings or houses under construction. Many people

are involved in this work like engineer, architect, contractor, mason, carpenter,

plumber and electrician.

Many people use different kinds of materials and

tools and work as a team to do their job.

An engineer who plans buildings and bridges is

focused on the building’s foundation. He draws up

how steel rods are arranged, how much concrete is

used etc.
