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. Figure 1: Coarse.

Chapter 2 The Ideal Aggregate

By-product of the steel industry. ○ When iron ore is heated to extreme temperatures, it becomes molten. ○ The heavy iron sinks to the bottom, while impurities rise to the top. ○ Impurities are poured off and quenched with water. This is slag. ○ Can then be crushed into various sizes. ○ Has a high specific gravity and high.
