aggregates yielded a minimum average slump of 63 mm since it has an angular shape and rough surface and absorbed more water. The results show that the natural river supply of aggregates is more practical than the other two options. The aggregates from other sources will require additional mixing water to yield good mix and compaction. TABLE 4.

Aggregates are intensively used in civil and transportation infrastructures. In specification ASTM C125-21 (), aggregates are defined as granular materials such as sand, gravel, and crushed stones or slag, used with a cementing medium to form hydraulic cement concrete or mortar.In specification JTG E42 2005 (), aggregates are defined as granular materials used in mixture …
