How do you calculate coarse aggregate?

The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg. Weight of coarse aggregate = 3 x 364.5 = 1093.5 kg.

How is aggregate calculated in slab?

  1. Cement Quantity= (Cement Part / Concrete Parts) x Concrete Volume.
  2. Sand Quantity= (sand Part / Concrete Parts) x Concrete Volume.
  3. Aggregate Quantity = (sand Part / Concrete Parts) x Concrete Volume.

Steps to Calculate Aggregate for MDCAT

  1. Marks obtained in HSSC /Equivalent x 1100 x 0.50 = 50\% of HSSC/Equivalent.
  2. Marks obtained in Entrance Test / SAT II / MCAT x 1100 x 0.50 = 50\% of Admission Test.
  3. Aggregate Marks x 100 = Aggregate Percentage.
