The environmental impact of concrete, its manufacture and applications, are complex.Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas.
It is concrete that is strong enough to carry a compressive stress of 3,000 psi at 28 days. Concrete may be specified at other strengths as well. Conventional concrete has strengths of 7,000 psi or less; concrete with strengths between 7,000 and 14,500 psi is considered high-strength concrete.
Disadvantages of Concrete: Concrete has following disadvantages: 1. Its tensile strength is very low of the order of 10% of the compressive strength. Thus it develops cracks. To avoid the development of cracks, steel is used as reinforcement. 2. Due to rise in temperature, concrete expands and due to fall in temperature it shrinks.
