Huge amount of construction and dem

Huge amount of construction and demolition wastes are produced
every year. In Thailand, these wastes are usually sent to
landfills or dumped illegally. The disposal of these wastes is a severe
social and environmental problem. The recycling of these
wastes as aggregate to produce new concrete can reduce the
problem of waste and help the preservation of natural aggregate
resources. Many researchers found that recycled aggregate offers a
good alternative aggregate for making concrete in terms of both
environment friendly and economically. Marinkovic et al. (2010)
studied the environment impact of recycled aggregate using life
cycle assessment (LCA) methodology (ISO, 2006) and reported that
the impact of aggregate production for recycled aggregate concrete
