Coarse aggregates are one of the most important ingredients of the concrete.
Coarse aggregates represent 50% of the weight of the concrete mix. , Dolomite is considered the best reliable material used as a coarse aggregate in the Middle East region.
Dolomite availability is limited in Egypt as it exists only in Ataka Mountain, where CEMEX quarry exists. We also apply state of the art technology in extracting and producing dolomite. This enables us to provide our clients with the desired size and shape that best fits their product specifications and needs.
