Concrete is a mixture of cement &/or supplementary materials (such as fly ash or ground granulated blast furnace slag), water, coarse and fine aggregates(crushed rock or natural gravel and sand), as well as some chemical admixtures where deemed necessary to improve the performance of the concrete. Concrete is produced in two classes, ‘Normal Class” and ‘Special Class’. Nucon supplies concrete complying with both classes. Normal Class concrete is defined in AS1379 and essentially complies with the basic performance requirements of that Standard. Special Class concrete is defined inAS1379 as concrete requiring any other or more stringent compliance with performance or prescriptive mix criteria.
