Increasing the amount of filler materials in concrete to decrease cement use

Cement, the main component of concrete, is one of the most important materials for all kinds of construction. Cement content is perceived to control concrete strength. Based on this perception, a minimum cement content is often specified that may exceed the amount needed to achieve the desired strength and durability. This excessive amount should be minimized to prevent its negative impact on costs and environment because:  

  • cement is the most expensive component in concrete  
  • cement contributes about 90% of the CO2 burden of a concrete mixture  
  • cement production emits approximately 5% of global carbon dioxide (CO2) and 5% of global energy consumption
