abstract = "Recently, research into finding long-term solutions to CO2 mitigation in the cement and
concrete sectors was initiated since commonly used supplementary cementitious materials
are not globally available in sufficient amounts. One of the possible solutions to that problem
is to develop concrete with a higher percentage of limestone in the powder phase. This work
presents a critical overview of the state-of-the-art in the field of the carbonation resistance of
limestone powder concrete. Experimental research performed so far has shown that if the
simple replacement of cement with limestone powder is applied in the standard mix design, a
maximum of 10-15% of cement (clinker) could be replaced to maintain similar carbonation
resistance. It has also been proven that the dilution effect of weakly inert limestone powder
can be compensated for with several measures in the mix design of concrete. By adjusting the
cement, limestone, and water content and their particle size distribution, it is feasible to design
concrete formulations with up to 50% limestone in the powder phase that are comparable to
referent Portland cement concrete in terms of rheological and mechanical performance and
carbonation resistance. This is an environmentally significant reduction in the clinker content,
but it comes at the cost of a larger superplasticizer content. Prediction models for the
carbonation resistance of the limestone powder concrete are poorly developed. Amongst
them, the fib MC 2010 prediction model is considered relatively simple and robust; however, it
has not yet been proven that the model is applicable to concrete with a higher content of
limestone powder (>15-20% of the powder phase). The future research should be oriented
towards further optimization of the concrete mix design and implementing this model on the
middle- and high-content limestone concrete carbonation.",
