Concrete has cement in its composition and therefore is a major contributor to global warming. In its chain, several mitigation opportunities are found. This study seeks to present the environmental impacts brought by the lack of quality control in the production of concretes, and possibilities of gains from improvements.
Based on the analysis of a state-of-art created from a concrete environmental impact indicator, and simulations of different scenarios, it was shown that, with small improvement in quality control, ~ 7% of CO2 emissions related to the chain could be mitigated. The lower the compressive strength of concretes, the higher the potential of gains from quality control improvement, which is relevant since most of the commercial concretes have low compressive strength.
