ABSTRACT
Recycling of concrete is an effort towards sustainable development using concrete. The benefits are economic, ecological and environmental. Reduced use of landfill space for waste dumping and conservation of natural rock resources are achieved; and in some cases, concrete recycling for use as aggregates may result in cost savings for construction projects. Concrete recycling is a well exploited practice in some Western countries, with large proportions of concrete waste being re-used. Japan, USA, Germany and Belgium recover 80 to 90% of construction and demolition waste with countries such as Netherlands and Switzerland achieving near 100% recovery. (WBCSD, 2006).
