Question

Difference between is method and deo method of concrete mix design

Answer 1

Concrete is a composite material consisting of cement, water, and aggregates. These ingredients can be mixed in different ratios to attain desired strengths. Though rough mix ratios for different strengths have been estimated such as for M20 (1:1.5:3), M25 (1:1:2) as per Gambhir [7]. But due to limited availability of materials and complex designs of structures, there’s a need for more accurate and precise mix proportions. Use of code provisions every time for calculating the mix proportion can be a tedious and exhausting process. Thus, dynamic program in excel was created for calculating mix proportions for different exposure conditions, aggregates size and properties desired.
