Cement is a crucial material in construction, often confused with concrete, which is a mixture that includes cement. Hydraulic cement hardens through hydration and is durable in wet conditions, while green cement is an eco-friendly alternative that utilizes recycled materials to reduce environmental impact. Concrete remains the most widely used construction material globally, with significant production concentrated in countries like China, India, and the USA.

1. Cement in Construction

2. Cement is a very important material in
building construction.
Although the terms cement and concrete
often are used interchangeably, cement is
actually an ingredient of concrete.
Concrete is basically a mixture of aggregates
and paste.

3. •Concrete is often the most economical choice.
•The material's ability to weather hurricanes and
tornadoes and its resistance to insects are valued.
•Builders also select concrete for its fire resistance.
•Four methods of concrete construction are
commonly used to create load-bearing walls for
low-rise construction:
‣ Tilt-up
‣ Precast
‣ Concrete masonry
‣ Cast-in-place.

4. • Hydraulic
• Non-Hydraulic
Cement Types

5. Hydraulic cements harden because of hydration,
a chemical reaction between the anhydrous
cement powder and water.
They can harden underwater or when constantly
exposed to wet weather.
The chemical reaction results in hydrates that are
not very water-soluble and so are quite durable in
water.

6. Non-hydraulic cements do not harden
underwater, like slaked limes harden by reaction
with atmospheric carbon dioxide.

7. Green cement is a cementitious material that
meets or exceeds the functional performance
capabilities of ordinary cement by incorporating
and optimizing recycled materials.
It reduces the consumption of natural raw
materials, water, and energy, resulting in a more
sustainable construction material.
The manufacturing process for green cement
succeeds in reducing and even eliminating the
production and release of damaging pollutants
and greenhouse gasses, particularly Carbon-
dioxide.

8. The most important uses of cement are:
• Ingredient in the production of mortar in
masonry
• Ingredient in the production of concrete, a
combination of cement and an aggregate to form
a strong building material.
Cement Uses

9. •Twice as much concrete is used in construction around
the world than the total of all other building materials.
•Slightly more than half of all low-rise buildings in the
United States are constructed from concrete.
•The annual global production of concrete is about 5
billion cubic yards.
•The Global production of cement in 2000 was 1.56
billion tones, one-third of this was produced in China
alone.
•For the world capacity to produce cement in 2010, the
top three producers were China, India, and USA
accounting for just under half the world total capacity.
