The Potential for Using Some Alternative Aggregates in Structural Concrete

The environmental benefits of using waste materials in construction was identified as long ago as 1974. This paper describes the results of a project undertaken for the Department of the Environment, Transport & the Regions in which methods of utilising waste materials as alternative aggregates in structural concrete were explored. Three types of waste material were identified as potential aggregates: china clay waste, slate waste, and pulverised-fuel ash. IThe project investigated methods of utilising these materials as aggregate by low-cost processing and/or novel mix design. The results of the project were encouraging, since good quality concrete mixes were produced fron all three waste materials. A.K. Butler, D.S. Leek and R.A. Johnson
