2. MORTAR
A fine aggregate and water
mixed together in suitable
proportions , they form an
easily workable paste that
use for binding materials

3. FUNCTION OF MORTAR
To bind together the bricks or stones
properly so as to provide strength to the
structure.
To provide a weather resisting
To fill up empty joints in brick and stone
masonry.

4. DON’T
do not use dirty water
puddles or ponds (shallow pool)
sugar-containing liquids
soft drinks

5. Dry sand and cement in
wheelbarrow
Begin to mix sand and
cement
Mix to evenly distribute
cement
The dry mix should be all
one colour
Add water and plasticiser
Mix to required
consistency

6. CONCRETE HOLLOW
BLOCKS
Is a large rectangular brick
used in construction.
Portland cement and aggregate,
usually sand and fine gravel for high-
density blocks.

7. COMMON PARTSCOMMON PARTS

8. DESCRIPTION
•
Have one or more hollow cores.
•
In general, a hollow-core concrete block is
more than 50 % solid.
•
Standard hollow concrete blocks come in full
and half sizes.
•
Full-size blocks are rectangular and have two
cores.
•
Half size blocks are cubical and have one
core.

9. ADVANTAGES OF HOLLOW ADVANTAGES OF HOLLOW
CONCRETE BLOCKS. CONCRETE BLOCKS.
•
Highly Durable: The good concrete compacted
by high pressure and vibration gives substantial
strength to the block. Proper curing increase
compressive strength of the blocks.
•
Low Maintenance
•
Fire Resistant
•
Provide thermal and sound insulation
•
Economical
•
Environment Friendly

10. Structural Advantages Structural Advantages
•
Reducing the vulnerability (exposed to damage) of
disastrous damage to the structure/building, during
the natural hazards.
•
Provide and offer better resistance under dynamic
loading

11. Constructional Advantages Constructional Advantages
•
No additional formwork or any special
construction machinery is required for reinforcing
the hollow block masonry.
•
Only semi-skilled labor is required for this type of
construction.
•
It is a faster and easier construction system,
when compared to the other conventional
construction systems.
•
It is also found to be a cost-effective disaster
resistant construction system

12. Architectural and Other
Advantages
•
This construction system provides better acoustic
and thermal insulation for the building.
•
Faster construction: - Easy to work with bigger in
size.
•
Recommended for earth quake resistance.
•
Less water absorption:- Approx. 3 to 4%
•
Environmental Eco-Friendly
•
This system is durable and maintenance free.
•
No leaching: - Reduction in maintenance.
