(same as grade of concrete, see table below) Concrete IngredientsĬalculate the target compressive strength of concrete using the formula given below.į ck’ = Target compressive strength at 28 days in N/mm 2.į ck = Characteristic compressive strength at 28 days in N/mm 2. After doing the test, store the test data for further calculation. The table given below shows the list of most necessary tests to be done on cement, coarse aggregate, fine aggregate and admixture. Type of aggregate (angular, sub angular, rounded etc).Early age strength requirement (if any).Maximum temperature of concrete at the time of placing.Exposure conditions (As per IS-456-Table-4).Grade designation (whether M10, M15, M20 etc).The data required for mix proportioning is as follows. This is the step where we gather all the required information for designing a concrete mix from the client.
