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.

AB  - A parametric analysis of deflection control of reinforced recycled aggregate concrete (RAC) one-way members is presented in this study. Within the study, member boundary conditions, ambient conditions (relative humidity), reinforcement ratios, and quasi-permanent–to–design load ratios (as per the Eurocode framework) are varied. Through the analysis, the change in deflections is observed relative to the substitution ratio of RCA (from natural aggregate concrete, NAC, to RAC with 100% of coarse RCA) and span-to-effective depth ratio (L/d). The results of the analysis enable a clear overview of the variability of the deflections of RAC members relative to NAC.

AB  - Fibre reinforced concrete (FRC) is increasingly being used in elements with high structural responsibility, the constructed FRC column-supported flat slabs (CSFSs, hereinafter) with partial or even total substitution of reinforcing steel bars being a supporting evidence for that statement. These pioneer experiences provide encouraging results with respect to resource optimization and construction time reduction without jeopardising the structural reliability. Despite such promising achievements, the use of FRC in CSFSs is still limited in the building sector. To provide an additional impulse for the use of FRC, a comprehensive comparison between FRC and traditional reinforced concrete (RC) technologies for CSFSs in terms of execution procedure and overall costs is needed. With this in mind, an industrial-oriented study was carried out with the main objective of elaborating a simplified method for the preliminary comparison of RC and FRC solutions. This method permits to assess the major amount of the required reinforcement (flexural reinforcement) followed by an evaluation of the time saving effect due to the partial or total substitution of reinforcing steel bars by fibres. For this purpose and for the sake of generalization, several databases were examined and 33 interviews with experts on in situ construction were conducted so that a wide range of productivity rates and other particularities could be identified. Based on the proposed method, a case study was analysed in order to indicate the potential direct costs (materials + labour) for a number of RC and FRC solutions using data from the examined databases and conducted interviews. The results reflect an increment of direct costs for both fibre and hybrid (fibre + reinforcing steel bars, HFRC) solutions; however, these increment can be compensated by the reduction of the construction period and, as a consequence, time-dependent costs (i.e., preliminaries, equipment costs, overheads, and finance costs). The outcomes of this research are meant to provide support to designers and construction planners with regard to the suitability of using FRC for CSFSs.

AB  - With increasing construction activity and concrete consumption globally, the economic,
environmental, and social impacts of human activities continue to increase rapidly. Therefore, it is
imperative to assess the choice and construction of each structure and structural component from a
sustainability-based perspective. In this study, such a multi-criteria decision-making approach using
the MIVES method is applied to the choice of grouped continuous flight auger (CFA) piles. Different
alternatives of CFA piles are studied: length (10 and 20 m), reinforcement (steel cage reinforcement
and structural fibers), and aggregates (natural crushed aggregates and recycled aggregate concrete
sourced from stationary and mobile recycling plants), based on experimentally verified mix designs.
All alternatives were analyzed considering economic, environmental, and social requirements, using
a decision-making tree with eight criteria and eleven indicators, with weights assigned by an expert
panel. The results of the analysis showed a clear advantage in terms of all three sustainability
requirements for CFA piles with steel fibers and recycled aggregate concrete, with all solutions with
steel cage reinforcement having significantly lower values of the sustainability index. Such results
demonstrate the need for implementing innovative solutions even in structural members such as
CFA piles that are often considered in insufficient detail.

AB  - Recycled aggregate concrete (RAC) is a promising solution to addressing the sustainability issues raised by concrete production. However, its long-term properties are not fully characterised, especially creep behaviour, which is significant for the design of RAC structures. This study presents the results of a meta-analysis of previously published research on the creep behaviour of recycled aggregate concrete (RAC). The main goal of the study is to formulate an analytic expression for the creep coefficient of RAC as an extension of the fib Model Code 2010 creep prediction model. A database of experimental results on the creep of RAC and companion natural aggregate concrete (NAC), produced with the same effective water-cement ratio, was compiled from available literature and using strict selection criteria. The database is comprised of results from 10 studies, 46 creep curves (14 NAC and 32 RAC) and 233 data points. Compared with companion NAC, RAC displays a larger creep coefficient; the difference between RAC and NAC increases with increasing recycled concrete aggregate (RCA) content and decreases with increasing RAC compressive strength. When predicting the creep coefficient of RAC using the fib Model Code 2010's creep prediction model, relative to the model's performance on companion NAC, the creep coefficient of RAC is underestimated. A correction coefficient for the creep coefficient of RAC, xi(cc.RAC), is proposed for use with the fib Model Code 2010 model, dependent on RAC compressive strength and RCA replacement ratio.

AB  - This paper presents experimental results of long-term behavior of reinforced beams made from natural aggregate concrete (NAC), recycled aggregate concrete (RAC), and high-volume fly ash concrete (HVFAC) under sustained load. Two 3.2 m span simply supported beams were cast from each concrete type and loaded after 7 and 28 days for a period of 450 days. Deflections, cracking, and strains were measured on the beams. Mechanical properties, shrinkage, and creep were measured on accompanying concrete specimens. Results showed similar mechanical properties of NAC and RAC and lower values for HVFAC. Shrinkage and creep were largest for RAC and smallest in the case of HVFAC. All beams had similar increases in deflections relative to their initial deflections. Deflection results are compared with fib Model Code 2010 predictions. Good agreement is found with results for RAC beams, whereas predictions for HVFAC beams show a significant overestimation of experimental results.

AB  - This paper describes a meta-analysis of previously published studies on the shrinkage strain of recycled aggregate concrete (RAC). The study aims at providing an analytic expression for the shrinkage strain of RAC to be used in conjunction with the existing fib Model Code 2010 shrinkage prediction model. For this purpose, a database of experimental results on the shrinkage of RAC and companion natural aggregate concrete (NAC), produced with the same water-cement ratio, was compiled using strict selection criteria. Results from 19 studies entered into the database, consisting of 125 shrinkage curves (39 NAC and 86 RAC) with a total of 424 data points. A comparison of RAC and companion NAC revealed that, on average, RAC displays a larger shrinkage strain. This difference increases with increasing recycled concrete aggregate (RCA) content and with decreasing compressive strength. Applying the fib Model Code 2010 shrinkage prediction model revealed that, relative to its performance on NAC, the shrinkage strain of RAC is underestimated. Finally, a correction coefficient for the shrinkage strain of RAC, zeta(cs),(RAC), to be used in conjunction with the fib Model Code 2010 model, was proposed in the form of a bivariate power function with RAC compressive strength and RCA replacement ratio as variables.

Finally, a correction coefficient for the shrinkage strain of RAC, zeta(cs),(RAC), to be used in conjunction with the fib Model Code 2010 model, was proposed in the form of a bivariate power function with RAC compressive strength and RCA replacement ratio as variables.",
