dc.description.abstract | Considered an ancient technique, rammed earth has a significant heritage of buildings around the world. Raw earth construction, as well as rammed earth, has fallen into disuse in recent centuries due to new means of civil construction processes, resulting from technological advances and following contemporary cultural trends. However, with the increase in demand for industrialized inputs, there was a great demand for the use of natural resources and greater production of CO2, which contributes to global warming. Seeking to reduce the impacts, there was a return to the use of more sustainable materials and techniques, such as rammed earth techniques, in an attempt to minimize the high industrial consumerism. The mining process is one of the major causes of negative environmental impacts, within the processes carried out in mining is its disposal of tailings, generating financial waste, being an additional cost for mining companies. In order to use iron ore tailings in rammed earth walls, research was carried out to study its technical, environmental and economic feasibility. It can be seen that there is technical feasibility in the use of mining tailings in rammed earth, replacing sand for stabilization, as the tailings are fine and can fill in the empty spaces in the rammed earth, making the mixture denser. As well as the environmental viability, as it is considered an alternative with low environmental impact, in addition to making use of the material that would be in the dams, bringing risk to nearby communities and distorting the landscape. It has economic viability, in relation to the transport distance from the mine to the place of use, also considering the value of conventional aggregates. | |
