Acesso em:.https://repositorio.ufpa.br/handle/2011/7925Water is an essential substance in order to have life and as well as being a fundamental human right to water is also used in food production, services and consumer goods. Water is present in construction in real and virtual form. The water that is use in the extraction of raw materials, manufacturing of building materials and during the lifetime of the buildings and the virtual water is incorporate into the product. The construction industry is one of the fastest growing economic sectors in the world and therefore has become a major consumer of natural resources. In Brazil, the number of investments for housing has raised the number of buildings in the country and has caused builders seek technologies to reduce the time of execution of works. One such technology is the use of ready-mix concrete; a product manufactured in metering stations, which has as main advantages, the rationalization of the workforce and reduced the concrete runtime. By the growth in the use of ready-mix concrete and concern about water scarcity, this work proposed verify the presence, importance and economic value of the real and virtual water as raw material in ready-mix concrete produced in the metropolitan region of Belém-PA, therefore, although present throughout the concrete production process for the water is not assigned any economic value. When entering the real and virtual water in the unit prices of composition percentages of increases in the value of cubic meters of ready-mix concrete would be less than 1% for real water and 36% for virtual water. These increases although there are not added to the final price of manufacture of concrete. Therefore, one must consider the importance of this natural resource in the construction segment, in order to ensure the maintenance and quality of life for this and future generations.Acesso AbertoÁguaÁgua virtualConstrução civilConcreto usinadoRecursos hídricosWaterVirtual waterConstructionReady-mixed concreteWater resourcesDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA SANITARIA::RECURSOS HIDRICOS
