An Eco-Block is an environmental-friendly brick made from recycled materials and construction waste. The brick was invented by the Hong Kong Polytechnic University in 2006. Its major feature is to catalyze the nitrogen oxide and other pollutants in air into non-hazardous substances. Eco-Blocks have been mainly used as paving brick in ...
Smaller pieces of concrete are used as gravel for new construction projects. Crushed recycled concrete can also be used as the dry aggregate for new concrete if it is free of contaminants.
