The existence of some substances in concrete, like useful and unwelcome additives, could cause wellbeing worries because of toxicity and radioactivity. Fresh concrete (right before curing is finish) is extremely alkaline and must be taken care of with appropriate protecting devices.

In distinction, recycled masonry aggregates provide greater features when crushed in finer fractures. With each generation of recycled concrete, the resulting compressive energy decreases.
