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 ...

Dec 01, 2017· The grading curves show a uniform grading for all the aggregates. In that sense, the uniformity coefficients (C u) of Basalt, BFS, CW, and RCA are equal to 2.20, 1.80, 2.16 and 1.86, respectively. These values are close; hence, the difference of the aggregate grading distributions is considered not significant .

Sub-bases | Pavingexpert

The sub-base layer is often the main load-bearing layer of a pavement. It is designed to evenly spread the load of the paving, and any traffic thereon, to the sub-grade below. A well-constructed sub-base will aid drainage and prevent settlement and channelisation - the phenomenon common on cheap installations of block paving, where two ''ruts'' develop in the paving.
