  • What are the Sources of Natural Aggregates?

    Aggregates are the most important constituents in concreteThey give body to the concrete, reduce shrinkage and effect economy Natural aggregates are inert granular materials such as sand, gravel stone or crushed stone that are used with a binding medium ie water, bitumen, portland cement, lime, etc to form compound materials ie asphalt concrete and portland cement concreteRecycled Aggregate Characteristics The crushing characteristics of hardened concrete are similar to those of natural rock and are not significantly affected by the grade or quality of the original concrete Recycled concrete aggregates produced from all but the poorest quality original concrete can be expected to pass the same tests requiredRecycled Aggregates Portland Cement AssociationGranite is a common and widely occurring type of intrusive, felsic, igneous rock Granites are usually medium to coarsely crystalline, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry Granites can be pink to dark gray or even black, depending on their chemistry and mineralogyGranite Mining, processing, products & markets
