Abstract

The paper descriptionbed an investigation which had been carried out to determine the concrete- and mortar-making properties of crusher sand derived from the crushing of Witwatersrand quartzite at two different crushing plants. It was concluded that such crusher sand, manufactured under controlled conditions, warranted consideration for use in concrete and mortar.
