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.

Concrete Volume

Cubic Yards Required:

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.

Block Wall

8 inch
12 inch
Cubic Yards Required:

To use the Block Wall Calculator, simply enter the height and length of the wall, click on whether you are filling an 8-inch or 12-inch 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 open-ended bond beam (lintel) blocks.


Cubic Yards Required:

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.

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


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


Low Maintenance
  • Concrete, being inert, compact and non-porous, does not attract mould or lose its key properties over time


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


  • Being naturally fire-resistant concrete forms a highly effective barrier to fire spread


Relatively low emissions of CO2
  • CO2 emissions from concrete and cement production are relatively small compared to other building materials.
  • 80% of a buildings CO2 emissions are generated not by the production of the materials used in its construction, but in the electric utilities of the building over its life-cycle (e.g. lighting, heating, air-conditioning)


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

Excellent Thermal Mass
  • Concrete walls and floors slow the passage of heat moving through, reducing temperature swings
  • This reduces energy needs from heating or air-conditioning, offering year-round energy savings over the life-time 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 CO2 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. air-conditioning
