RESUMO:

Ultra high performance concrete (UHPC) is a concrete with high durability, low porosity and mechanical strength over 150 MPa. UHPC’s high durability and strength are obtained using particle packing models for the optimization of the compositions and make possible the construction of lighter structures with smaller cross-sections and longer life spans that can result in reduced environmental impacts. However, the high consumption of cement, around 900 kg/m³ is a obstacle in this aspect. In this context, the present study aims to measure the impacts generated by UHPC and to evaluate if the reduction in concrete consumption and the increased serviceability of the structure compensate the impacts caused by the large amount of cement used. For the analysis, the life cycle assessment (LCA) emerges as an essential tool for the development of the work. In this work UHPC compositions will be produced and, considering the obtained mechanical strength, structural elements will be designed to compare with the dimensioning of the same element in conventional concrete. With the quantity of the materials for compositions and the amount of concrete in the elements, a life cycle assessment will be performed to compare the impacts between UHPC and conventional concrete. It is expected that the study contributes to the optimization of UHPC production and that the results help in understanding the feasibility of ultra high performance concrete and its environmental impacts.
