Title: Properties of a range of Environmentally Friendly Light-Weight Concrete
Appears on pages(s):
Abstract:In this study, light weight structural grade concretes were prepared using various binders and a range of aggregates with emphasis to use maximum amount of waste or byproducts. Binders used were combinations of a general purpose Portland (GP) cement and unclassified fly ash (FA). The amount of fly ash used ranged from 30 to 50% by weight of the total binder. Aggregates used were bottom ash aggregate and scoria. Also bottom ash sand and manufactured sand was used as the fine aggregate. Concretes were prepared with a range of 28-day strengths and densities and thereby a concrete can be selected to suit a particular application. Consideration was given that the concrete obtained adequate strength at the age of about 18 to 24 hours to facilitate the demolding. Thus one batch of concrete was prepared at the pre-cast plant everyday. It was demonstrated that a range of light-weight concrete can be prepared which contain predominantly waste materials/by-products and has adequate strength to allow demolding at an age of 18 to 24 hours. Concretes were prepared with air-dry densities ranging from 1600 to 2000 Kg/m3.
