Aggregates - SlideShare

Hardness of aggregates Hardness of aggregates is the ability of the aggregate to withstand wear or load or applied pressure. This hardness is depending on the type of parent rock The test that can obtain the hardness is the abrassion test. A satisfactory aggregate should have an abrassion value of not more than 30% for aggregates used for .

What is the significance of specific gravity of

The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the fine aggregate specific gravity test.

The Density of Common Rocks and Minerals

The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
