A Survey of building sands in northern New South Wales
TL;DRAbstract
Mortar sands were collected across a large area of northern NSW and analysed to assess their suitability for masonry construction. Grading curves of 50 sands collected are presented and compared with requirements for building sands and mortars. Results for flexural bond strengths developed using nineteen of the sands are presented and compared with AS 3700 requirements. As well, the current extent of sand extraction within the study area is outlined. Environmental impacts of these processes are considered and opportunities for recycling and use of alternative waste materials are also discussed briefly.
