The use of waste materials for concrete production in construction applications

To sustain the environment, it is crucial to find solutions to deal with waste, pollution, depletion and degradation resources. In construction, large amounts of concrete from buildings’ demolitions made up 30-40 % of total wastes. Expensive dumping cost, landfill taxes and limited disposal sites gi...

The study reveals that slag and fly ash are effective supplementary elements in improving the properties of the concrete with cement.
