Mix design plays an important role in civil construction works. In order to obtain the perfect quantity of any construction site, use this user-friendly concrete mix design spreadsheet that is based on excel program. This useful construction sheet will provide you the quantities of mix design for your construction site.
The concrete mix design refers to a method for choosing proper ingredients of concrete as well as ascertaining their proportionate values so as to generate a concrete of the optimal strength, resilience, and feasibility as cost-effectively as possible.
Requirements of concrete mix design.
The following properties are necessary to develop basis of choosing and proportioning of mix ingredients:
The least compressive strength is necessary from structural consideration
The sufficient workability is needed for complete compaction through the ontainable compacting equipment.
Utmost water-cement ratio and/or utmost cement content to provide enough strength for the specific site conditions
Highest cement content to get rid of shrinkage cracking because of temperature cycle in mass concrete.
