Concrete Mix Design Worksheet for SSD condition.

AUTOMATED EXCEL SHEET FOR CALCULATE CONCRETE MIX DESIGN

What is mix design?

• Mix design is a design of a concrete for specific grade of concrete for gaining specified strength on 28 day by testing of sample cube on 28 day.
• Purpose of calculation of mix design is that finding out proportion of material use for specific strength of concrete.
• This Excel sheet based on IS code 10262:2009 & IS code 456:2000.
