Resumo

Compressive strength and CO2 emissions of Portland cement (CP) matrices were evaluated, with the replacement of 0%, 7%, 15%, and 25% of concrete waste as a function of waste processing time (0, 0.5, 2, and 6 h). The results indicate that the compressive strength in the matrix, with 15% and 25% of treated waste, meets the requirements for class C40, and C32 of the Brazilian technical standard for PC, with the potential to mitigate emissions per ton of cement by up to 25%. With concrete waste, it was possible to reduce 13% of cement consumption/MPa
