ON THE COVER: Major South African construction company Concor is currently building a super-basement in Sunnyside, Pretoria as the first phase of the Trevenna Office Campus. It is part of a larger venture driven by the Public Investment Corporation (PIC). This expansive 68 000 m2 basement will service the future three A-grade office buildings of this campus. AfriSam, a leading supplier of superior quality construction materials and technical solutions, is supplying the readymix concrete for the second half of this project. Construction World recently visited the bustling urban site where readymix deliveries must be timed meticulously to suit the construction programme.
CHRYSO’S SUSTAINABILITY SOLUTIONS FOR SWELLING CLAY AND FINES
As the construction sector aims to achieve more demanding sustainability targets – including a lower carbon footprint – the CHRYSO®Quad range presents valuable opportunities for dealing with challenging sands. The shortage of natural sand is a growing environmental issue in countries like South Africa and indeed across the African continent as it is a non-renewable resource, explains Patrick Flannigan, Technical Manager in the Concrete Business Unit at CHRYSO Southern Africa. The trend is to use more manufactured sand, usually sourced from stone crushing operations – and hence also called crusher sand. When contractors have to truck sand to site over long distances, this extended value chain adds to the carbon footprint of the product and project.
