Its production and use have an enormous impact on society and environment and are an important economic factor worldwide. A large labor Abstract force is employed in this industrial sector, has income, pays taxes and thus supports both their families and the surrounding communities. The infrastructure made with concrete shapes the environment for decades and demands large investments of the society.
