[PT] The construction sector is responsible for high consumption of raw materials and intensive waste generation, and is working on the creation of procedures and products, increasingly seeking sustainability. Self-compact concrete (BAC) allows the production of greener material, for example by reusing industrial waste. In this work, an experimental programme has been developed to optimise BAC compositions incorporating the residue from the improvement of marble from the Alentejo region in Portugal, known as the Mármore Area. The experimental programme was carried out following a factorial plan at concrete level, fixing the composition of the paste in order to optimise the solid skeleton formed by the aggregates. The results obtained led to the conclusion that it is possible to replace cement with marble powder without significantly affecting the properties of self-compacting and thus achieving lower resistance and more eco-efficient BAC compositions suitable for a wide variety of structural concrete applications.
