In addition, the process energy usage and greenhouse gas emissions from natural crushed aggregate is around 7.4 to 8.0 kg of equivalent CO 2 emission per tonne. The emissions from trucks and dumpers, as well as use of crushers which result in considerable dust and particulate emissions, increase global warming [13,14,15]. The concrete production process generates a high demand for aggregates which will inevitably lead to a sparsity of resources as demand increases.
