AB  - The efficient way to mitigate the impact of the concrete industry on climate change is to reduce the clinker content in the concrete mix. Beside incorporating supplementary cementitious materials (SCMs), it is possible to use high filler content combined with concrete mix optimisation. Limestone powder emerges as a promising filler mineral due to its availability and ready-to-use technology. In this work, the carbonation resistance of concrete with a high limestone powder content (45–65% of the powder phase) was experimentally tested. Test results showed that, with an optimized mix design featuring low water content and increased paste and plasticizer volume, concrete mixes satisfied high workability and strength demands for commonly applied strength classes. However, carbonation resistance remains a challenge. After two years in indoor natural conditions, carbonation depths were 8%, 28%, and 67% greater than referent Portland cement concrete for mixes with 47%, 58%, and 65% limestone powder content, respectively. Further analyses showed the inapplicability of the existing fib Model Code 2010 service life prediction model to limestone powder concrete. Based on a comprehensive database of experimental results, the modification of the fib prediction was proposed. A full probabilistic service life analysis revealed that for concrete with more than 20% limestone powder content and for both 50 and 100-years’ design service life, the currently prescribed concrete cover depths in European standards should be increased, depending on the carbonation exposure class.

AB  - One of the paths to CO2 emissions reduction in the concrete industry is to use low-clinker cements, providing at the same time the performance of concrete that is adequate for application in concrete structures. This paper explores the impact of the clinker replacement with high amounts of limestone powder (21–70% in the powder phase) on concrete carbonation resistance. To quantify this impact, the empirical relationship between the carbonation resistance and the compressive strength of the high-volume limestone powder concrete (HVLPC) was established. For that pur-pose, the regression analysis was applied on the experimental results collected from the published research. The service life analysis based on the full probabilistic approach was performed using the fib Model Code 2010 prediction model and proposed empirical relationship. The first-order relia-bility method (FORM) was applied to solve the limit state function of reinforcement depassivation with a reliability index equal to 1.3. The obtained minimum concrete cover depths were 40–110% higher compared to those prescribed in the current European standard EN 1992-1-1:2004 for in-dicative strength classes. Based on the full probabilistic analysis, recommended cover depths are given for all carbonation exposure classes, commonly applied concrete strength classes, and service lives of 50 and 100 years.

AB  - 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.

AB  - Producing limestone powder requires comparably far less energy than the production of ordinary
Portland cement (OPC), making it a promising sustainable solution for partial replacement of OPC
in concrete. Lower production energy could be translated into lower environmental impact and
lower cost, which are two pillars of the sustainability of the resulting concrete. However, the
question remains if replacing OPC with larger percentages of limestone powder would compromise
the performance of the resulting concrete to a level that surpasses the environmental and
economic gains. In order to assess the collective impact of these concretes, a performance-based
multi-criteria decision analysis framework, ECO2, is used. For that purpose, 26 experimentally
verified, concrete mixtures with and without limestone powder were evaluated through potential
application in two types of reinforced concrete (RC) structural elements (slabs and columns)
under identical environmental condition. The main results of the research showed a clear environmental advantage of concrete with a reduced OPC content, but the relatively higher superplasticizer amount in some cases could affect the final sustainability performance of the resulting mix. In the case of RC slabs, the best ECO2 score was obtained for concrete containing limestone powder. Mixtures with 200–250 kg of cement per unit volume of concrete had the highest ECO2 score for all the considered criteria. In the second case, due to the nature of the structural performance requirements in columns, the crucial influence of the concrete compressive strength is clear. The obtained results have shown approximately equal sustainability potential of OPC and limestone concretes in vertical elements such as columns. However, it seems that a certain improvement in the design of concrete mixtures with a high limestone powder content could
make these competitive in all fields.

environment for future generations. The need for cement implies the extremely high use of relatively expensive energy, evident in all segments of production and application. The use of fossil fuels during cement production is the main problem for creating the greenhouse effect and climate change. Until the end of this decade, about 10% of total CO2 emissions of anthropogenic origin will be a consequence of cement production. In order to preserve the competitiveness of concrete as the most widely used building material, it is necessary to take appropriate actions to promote sustainable development. In that way, a cement replacement with a cheaper and cleaner product – filler could have a significant global contribution.

AB  - It is estimated that by the end of the current decade, about 26% of clinker will be replaced by suitable alternative materials, among which limestone filler probably has the greatest potential due to its wide availability and relatively low price. Although codes allow as much as 35% of clinker to be replaced by limestone filler, the amounts used in practice are far less and average only 6-7% globally, with no growth trend over the past ten years. In order to use the great potential of fillers, it is necessary to know the key parameters that affect the properties of green concrete with low cement and high filler content in fresh and hardened state. For that purpose, a total of 18 concrete mixtures were designed, in order to analyse the effects of the percentage of cement replacement, water-cement ratio, but also the particle size of the applied filler. The results of experimental research show that at the same w/c ratio there is an increase in compressive strength with increasing percentage of cement replacement and that it is possible to make medium-strength concretes with a significantly reduced amount of cement (180 kg/m3) compared to traditional concretes. In this way, economic benefits can be achieved, but also the negative impact of the cement industry on the environment can be reduced. Unfortunately, the workability of such mixtures can be impaired to the extent that their practical application is prevented, so it is necessary to take further steps to solve this problem.

This paper presents the results of applying analytical and numerical calculation models for predicting deflections of reinforced natural aggregate concrete, recycled aggregate concrete and high-volume fly ash concrete beams. Experimental results on six simply supported beams were compared with predictions obtained using the fib Model Code 2010 analytical model and a numerical model formulated using DIANA.
