20 mm aggregates are used in reinforced concrete work. Bulk Density of Aggregate. Bulk density is the weight of aggregate …Answer Posted / ketan vadgama Density of 20-40 mm Aggregate 1450-1550 kg/cum Say 1cft weight = 1450-1550/35.31 = 41.06-43.90 kg/cftgranite aggregate is 35Mpa [7]. The concrete strength of combine aggregate 10mm and 5mm size can achieve 160Mpa at the age of 28 days [3]. The compressive strength of concrete cubes aggregate size 20mm and 10mm on the 7th days are 25.5Mpa and 16.9Mpa. Comparison percentage is 47.6%. Density concrete aggregate size 20mm and 10mm are 2368This standard is based on the testing of concretes of fixed mix proportions and aggregates of 20 mm maximum size. NOTE 1 Guidance on the use of larger size is given in Annex A. Precision data is not available for variations in size and for variations in the water content of the test concrete.The effects of aggregate type,
