FICAP Resources
The Concrete Calculators help you to estimate the required
concrete volume for a pour or placement, the volume of concrete needed to fill a block,
and the volume of concrete needed in a column.
To use the Concrete Volume Calculator, simply
enter the width, length, and thickness of your pour, click on whether you are measuring
the thickness in feet or inches, then click on the Calculate button. The
calculator will estimate the number of cubic yards of concrete that will be required.
To use the Block Wall Calculator, simply enter the
height and length of the wall, click on whether you are filling an 8inch or 12inch wall,
then click on the Calculate button. The calculator will estimate the
number of cubic yards that will be required. Note that this is an estimate.
There is significant variation in fill space among different blocks. This calculator
assumes the use of double openended bond beam (lintel) blocks.
To use the Concrete Column Calculator, simply enter the height and diameter of the column, and click on the Calculate button. The calculator will display the number of cubic yards required.
Note: These calculators are provided as a reference for the convenience of our members and site visitors. They have been created using standard ready mix concrete industry measurements and formulae. No allowances have been made for variations in grade thicknesses, dimensional errors in width or length, waste, spillage, or shrinkage.

Characteristics of Concrete
Strength and Durability 
 Used in the majority of buildings, bridges, tunnels and
dams for its strength
 Gains strength over time
 Not weakened by moisture, mould or pests
 Concrete structures can withstand natural disasters such
as earthquakes and hurricanes
 Roman buildings over 1,500 years old such as the
Coliseum are living examples of the strength and durability
of concrete

Versatility

 Concrete is used in buildings, bridges, dams, tunnels, sewerage
systems pavements, runways and even roads.

Low
Maintenance 
 Concrete, being inert, compact and nonporous, does not attract
mould or lose its key properties over time

Affordability 
 Compared to other comparable building materials e.g. steel,
concrete is less costly to produce and remains extremely
affordable

FireResistance

 Being naturally fireresistant concrete forms a highly effective
barrier to fire spread

Relatively low
emissions of CO_{2}

 CO2 emissions from concrete and cement production are
relatively small compared to other building materials.
 80% of a buildings CO_{2} emissions are generated not by
the production of the materials used in its construction,
but in the electric utilities of the building over its
lifecycle (e.g. lighting, heating, airconditioning)

Energy Efficiency
in Production 
 Producing concrete uses less energy than producing other
comparable building materials.
 A study quoted by the NRMCA concluded that the energy
required to produce one ton of concrete was 1.4 GJ/t
compared to 30 GJ/t for steel and 2GJ/t for wood

Energy of Production for Common Materials
Source: National ReadyMixed Concrete
Association (NRMCA)
Excellent Thermal Mass

 Concrete walls and floors slow the passage of heat moving through, reducing temperature swings
 This reduces energy needs from heating or airconditioning, offering yearround energy savings over the lifetime of the building
 One study quoted by the NRMCA found that concrete walls reduce energy requirements for a typical home by more than 17%

Locally Produced
and Used

 The relative expense of land transport usually limits
cement and concrete sales to within 300km of a plant site.
 Very little cement and concrete is traded and
transported internationally
 This saves significantly on transport emissions of CO_{2} that would otherwise occur

^{
Albedo Effect
The high "albedo" (reflective qualities" of concrete used in pavements and building walls means more light is reflected and less heat is absorbed, resulting in cooler temperatures
This reduces the "urban heat island" effect prevalent in cities today, and hence reduces energy use for e.g. airconditioning
