About concrete

So far, concrete is the strongest, most durable and most versatile construction material known to mankind. Although the concrete as we know today has been in use for only 150 years, its usage is widespread. Looking around we can conclude that no facility could be built without it. Concrete can be used in a variety of shapes and sizes.

Concrete is a solid material made from cement, aggregates and water, normally containing different additives. While concrete is fresh it has certain workability. This is one of the important advantages since this split time allows the concrete to be transported and processed during construction as it is necessary. When it begins to bind, it becomes as solid as natural stone and resistant to external influences such as water, frost, mechanical forces and fire. Concrete is used in all areas of constructions, in engineering work for roads, bridges, hydroelectric power plants, other industrial facilities, residential constructions and other.

It is not necessary for concrete to be grey and boring! Beautiful facilities and details could be shaped with concrete.


Concrete and sustainable development

Concrete provides a durable, stable and also favourable material that requires very little maintenance during its life time. The main long-term advantage of concrete is in increasing energy efficiency of buildings through all their lifetime. The key factor is “thermal mass” of concrete, the ability of concrete to help in regulation of inside temperature and consequently to reduce the need for air-conditioning in summer and heating in winter. The advantages of concrete are also in the aspect of fire safety, flood protection and sound isolation.

Besides the below mentioned sustainable approach to concrete and cement production, it is also important to look at the other aspect, that is the possibility of using different wastes as alternative fuels in the production of cement, which has no impact on the environment quality of the product. Such cement may be used without restrictions in the production of concretes and mortals, just as they can be recycled without any problems in the final phase, which is after the termination of their life-time. Therefore, the sustainable approach to construction brings both social and economic benefits.
