An overview of construction and demolition waste

2012-3-25  The construction and demolition (C&D) waste generated by the Canadian construction industry accounts for 27 % of the total municipal solid waste disposed in landfills. However, it is evident that over 75 % of what the construction industry generates as waste has a residual value, and therefore could be recycled, salvaged and/or reused. The need for comprehensive and integrated waste

QUANTIFICATION OF CONSTRUCTION MATERIAL

2010-1-14  Waste of materials in construction to a certain extent is unavoidable. Thus, any action taken to prevent the ‘unavoidable’ portion will create another waste in terms of either money or resources. However, Jayawardane (1992) noted that the wastage of materials in most of the construction sites in Sri Lanka is beyond acceptable limits.

An investigation into the use of waste materials for

Concrete is one of the most common construction material in the world, which contributes approximately 5% of man-made CO2 globally (C&CI, 2011). An increase in consumer resource consumption and waste production creates an opportunity for research into concrete which uses less virgin minerals, waste materials and has a lower cement content.
