Mass Concrete - What is Mass Concrete & Where It Is Used

Nov 22, 2017 · The concrete placed in different massive structures such as dams, bridge piers, canal locks, etc is known as mass concrete. In mass concrete, larger size aggregates (up to 150 mm maximum) and low slump (very stiff consistency) are used to reduce the amount of cement in the concrete mix (normally 5 bags per m3 of mass concrete).

Influence of cement strength class on environmental impact

However, cement is not a consumer product but rather a raw material for producing concrete and mortar. There is no representative database on the evolution of the CO 2 footprint of concrete and other cementitious products over time. As illustrated in Fig. 1(a), the clinker factor (i.e., mass fraction of clinker in cement) is linearly correlated (R 2 = 0.99) with the CO 2 emissions of cradle-to
