Note 1: The above recommendation are based on the fine aggregates and coarse aggregates are at saturated surface dry conditions. At the time of concrete production, adjustments are required to be made for surface moisture / water absorption in the fine aggregates and coarse aggregates. Volume correction is necessary for bulkage in the sand.
Note 2: For the recommendations to hold good it is necessary to ensure that the physical properties of the ingredients used at site do not deviate significantly form those given in the report.
