Aggregates were first considered to simply be filler for concrete to reduce the amount of cement required. However, it is now known that the type of aggregate used for concrete can have considerable effects on the plastic and hardened state properties of concrete. They can form 80% of the concrete mix so their properties are crucial to the properties of concrete.
Aggregates can be broadly classified into four different categories: these are heavyweight, normal weight, lightweight and ultra-lightweight aggregates. However in most concrete practices only normal weight and lightweight aggregates are used. The other types of aggregates are for specialist uses, such as nuclear radiation shielding provided by heavyweight concrete and thermal insulation using lightweight concrete.
aggregate crushing equipment
Jaw crusher is usually used as primary aggregate crusher for coarse aggregate crushing process. In the aggregate crushing plant, it is used to crush natural stones like limestone, feldspar and granite into coarse aggregtes.
Impact crusher can be used as aggregate crushing equipment in secondary aggregate crushing process. It is used to crush crushed aggregate into fine aggregate. In the complete aggregate crushing plant, cone crusher is also used as fine aggregate crusher machine.
