From Latin concrētus, concrete It is an adjective that allows mentioning something solid, material or compact The term is usually opposed to the general or abstract, since it refers to something determined and precise .

For example: "I don't want any more excuses, I need a concrete answer", “I told him my ideas but he asked me for a specific project and the truth is that I don't know what to say”, "After several hours of negotiations, it can be said that there is nothing concrete yet".

In the same way, we must not overlook that, in a very frequent way, we use in our everyday language an expression that incorporates this term that now occupies us. We are referring to "specifically." It is an adverbial phrase that we use as a synonym for "precisely."

All this without forgetting that there is also what is known as a specific number, which indicates the surface of a given area.

The concept has another use in several Latin American countries, derived from the English word concrete. In this case, the concrete is the mixture of stones and mortar also known as concrete . It should be noted that the mortar, on the other hand, is the mixture of cement, sand and water.

Concrete is a very frequent material in the building since it has the ability to withstand great compression efforts. However, it does not perform well in other types of efforts, such as flexion or traction. Therefore, concrete is often used in conjunction with the steel , in a compound that is called reinforced concrete .

It is common that various additives are added to the concrete to modify its characteristics. Among these additives it is possible to mention waterproofing, coloring and setting retarders, among others.

This type of material we have to underline that it already has its origin in Ancient Egypt and since then it would also be used in later centuries by other cultures and civilizations such as Greece or the Roman Empire. Precisely during this last historical period it should be noted that the concrete was used in part to set up important buildings such as the Colosseum in Rome.

Other unique information that is worth knowing about this material is that the first bridge created with it in its entirety was made in the French city of Souillac in 1816. And all this without forgetting that in the United States one of the most important works significant that used it as we know it today is the Erie channel.

The Panama Canal, the internationally famous Alcatraz prison and even the spectacular Sydney Opera House, located in Australia, are other amazing buildings that have also been built using part of the material at hand, specifically.

Residential buildings, bridges, tunnels and canals are some of the works that can be done with concrete or reinforced concrete. The world's leading concrete producer is China , followed by India , U.S , Japan and Russia , in that order.
