The base component for concrete mix, Concrete Sand is mixed with bluemetal, cement and water to achieve the desired mix. This sand can also be mixed with bluemetal and cement as a dry concrete premix when not required straight away. If you are carrying out concrete work, we can supply the bluemetal for your blend also. The size of bluemetal aggregate used in a concrete mix varies on personal preference, so please consult a concreter for aggregate size and mix ratios.
