Concrete Density - an overview | ScienceDirect Topics

The density achieved depends on the type of aggregate used. Generally, the increased concrete density is achieved using barite, magnetite, or hematite aggregates. When using barite aggregate, the density of concrete is about 3400 kg/m 3, which is 45% higher than that of ordinary concrete; with magnetite the density is equal to 3500 kg/m 3 —by 50% higher than that of normal concrete and with ...

Barium - Wikipedia

Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal cause of its high chemical reactivity, barium is never found in nature as a free element.. The most common minerals of barium are baryte (barium sulfate, BaSO 4) and witherite (barium carbonate, BaCO 3), both insoluble in water.
