Environmental Effects of Cement Production: A Review
A rise in cement production has led to a decline in nonrenewable resources like limestone. Extracting resources from natural ecosystems increases the risk of ecological imbalance and destroys the green environment, home to many plant and animal species. Rapid usage will likely deplete this limited resource in the near future.
Types and Causes of Concrete Deterioration
Carbonation-induced corrosion often occurs on building facades with shallow concrete cover. (70157) Carbonation of concrete also lowers the amount of chloride ions needed to promote corrosion. In new concrete with a pH of 12 to 13, about 7,000 to 8,000 ppm of chlorides are required to start corrosion of embedded steel.
