Concrete Density - an overview | ScienceDirect .Deze pagina vertalen

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 ...

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual ...
