A research on the use of recycled concrete in foam concrete

The debris waste of the torn concrete buildings that complete their lifespan is increasing worldwide every day. Therefore, alternative solutions are being developed so that construction wastes can be recycled both for the preservation of the natural environment and for economic reasons. In this thesis study, concrete wastes are reused within foam concrete. The foam concrete that can be produced with or without sand at different densities and proofing features through millions of foam bubbles provides low density, high temperatures and sound proofing. Low water and heat permeability increase the resistance against fire. Due to the fact that they ease the construction load since their unit weights are low, they are especially preferred in earthquake areas. Million-meter cubes of sand have been used within the process of urbanisation, and the use of it still goes on. This condition consumes the sand reserves at the river beds. By taking the scarcity of the sand in the river beds into consideration nowadays, this condition leads us to create alternative materials to sand for concrete so that there will not be serious raw material problems in the future. In this thesis, how efficient can the construction waste be for foam concrete was studied by comparing the mechanical and physical attributes of samples that would be produced using construction waste rather than sand with the samples produced by standard sand.
