Minimum Cement Content
The Minimum Cement Content may be entered on a Mix Design Form, provided the Specify Minimum Cement Content Check Box has been ticked.
Concrete specifications frequently stipulate mix requirements, which are designed to concrete durability by ensuring a minimum concrete strength. Sometimes a minimum cement content is specified.
If the Specify Minimum Cement Content Tick Box is ticked, you can enter a minimum cement content, which will be compared with the cement content required for concrete strength or against the required Cement and Pozzolan Content, if Pozzolan is to be included in the mix.
If the minimum cement content needed for durability is greater than the cement content needed for strength, durability considerations govern. A Modified Free water/Cement Ratio is used in the mix design and the strength will be greater than the minimum needed.
