How Can Concrete Be Environmentally Friendly

Advantages of concrete

Plasticity: concrete has good plasticity, so the modern use of concrete has good workability, basically can be designed into a variety of building construction in accordance with customer requirements.

Economy: Compared to other materials, concrete is relatively inexpensive, but also easier to achieve local materials, and therefore the use of concrete buildings, maintenance costs are relatively low.

Safety: Concrete has high strength, the highest strength can reach 130MPa in today’s engineering construction, in addition, concrete and steel also has a very strong bond, such a high strength structure can be a good guarantee for building safety.

Fire resistance: the fire resistance of concrete is also good, under normal circumstances, concrete has 1-2 hours of fire aging, compared with steel, it can be said that it is much safer, so concrete buildings will not be like steel buildings, softening and collapse.

Concrete can be applied to many kinds of structures in civil engineering, and it can be configured in different ways to become different types of concrete, so that it can meet various construction requirements.

Durability: the durability of concrete is also good, concrete itself is a durable material, such as the ancient Roman Empire is the use of concrete buildings, it is because of concrete to make the ancient Roman buildings can go through thousands of years of wind and rain and still standing.

Although concrete has so many advantages, the materials used in the manufacture of cement can have a negative impact on the environment, for example, the production of cement will burn calcium carbonate, which will discharge a large amount of carbon dioxide and some gases containing sulfur, these gases will form acid rain, which will produce the greenhouse effect, these industrial emissions will cause great damage to the environment. And according to the survey, one-third of the noise in urban life comes from the construction of construction sites, of which concrete pouring vibration noise accounts for the main part.

How Can Concrete Be Environmentally Friendly

To this end, more and more people began to explore the new production methods of concrete, in order to reduce the pollution of the environment, the emergence of new environmentally friendly concrete, making the problem solved. Environmentally friendly concrete is the use of steel mill waste slag, power plant emissions of fly ash, and cement for a reasonable ratio of concrete mixing, this new concrete not only greatly reduces the cost, and the former industrial waste into treasure, reducing the industrial waste pollution of the city. Eco-friendly concrete can not only meet the requirements as a structural material, but also minimize the load and adverse effects on the global environment, and can harmonize with nature and coexist with the environment. Therefore, as the most heavily used construction material by mankind, the direction of development of concrete is bound to meet the needs of modern people, but also to consider environmental factors, which is conducive to resource and energy conservation and ecological balance, and environmentally friendly concrete has become the main direction of development of concrete.

Environmentally friendly concrete has so many advantages, it is no wonder that it has become the most popular and a building material in civil engineering now.
