The document outlines the different types of concrete blocks used in commercial construction, specifically solid and hollow blocks, detailing their composition, applications, and advantages. Solid concrete blocks are load-bearing and used widely due to their strength, while hollow concrete blocks are lighter, easier to install, and cost-effective due to reduced mortar usage. The document also provides standard sizes for hollow blocks and emphasizes the importance of consulting professionals for optimal installation.

1. Various Concrete Blocks type to use in
Commercial Construction

2. Concrete blocks
 Concrete blocks are of various types
depending on what purpose you want it to
serve, concrete blocks are made in three
different types, which includes, Solid, Hollow,
interlocking.
 Concrete blocks are classified into different
categories depending on their densities.
Density is determined by the amount of and
type of aggregate added to the concrete to
produce normal weight, medium weight, and
light weight concrete blocks.

4. Solid Concrete Blocks

5. Solid Concrete Blocks
 Solid concrete blocks are made with cement, aggregate
and water, solid blocks, it is always called the load
bearing blocks, the solid concrete block can be used in
wide range of varieties because of its strength than other
building blocks.
 Solid concrete blocks are 55% solid while hollow concrete
blocks are 25% solid. Solid concrete blocks use mortar for
its installation while using it for construction, a mortar is
used to hold two solid concrete blocks together and
making of the foundation, a mortar can be applied using a
trowel and this type of installation can be done by DIY.
 We have different types of mortar, so it may be wise to
seek advice from the professionals on how to get the best
one.

6. Hollow Concrete Blocks

7. Hollow Concrete Blocks
 Hollow concrete blocks are referred to as
concrete blocks that have core void larger than
the gross area of the whole blocks.
 hollow concrete blocks are of different types
depending on their sizes and shapes.

8. Standard sizes of Hollow
Blocks
 Standard size hollow concrete blocks- 39cm*19cm*39cm
 Hollow building tiles- 39cm*19cm*20cm
 Hollow concrete blocks for partitions- 39cm*19cm*10cm.
 All the types mention here are always 5cm thick(Face
Thickness), hollow concrete blocks are of uniform and
regular sizes which facilitate quick and good execution of
commercial projects, unlike solid concrete blocks
 Its helps in saving cost of construction by reducing the
numbers of joints in building constructions by saving the
mortal, hence, saving the cost.

9. Advantages of Hollow Concrete
blocks
 Hollow concrete blocks are light and easy to
install.
 They are strong and well insulated by the
block factory machines.
 They are used for construction in seismic
areas.
 Though taking a desultory look at hollow
concrete blocks, they are not always smooth
but are durable.
