Abstract Mechanochemical activation (MCA) is a rapidly emerging technology for producing supplementary cementitious materials (SCMs). However, performance data on MCA SCMs is lacking. Here, we investigated the potential use of four low-grade materials as sources of alternative SCMs following MCA treatment. The studied materials were municipal solid waste incineration bottom ash…

Abstract Continuous shrinkage measurement in earth-based materials remains technically challenging, particularly for high-water-content mixtures with low initial stiffness. In this study, a semi-cylindrical experimental setup, combined with digital image correlation (DIC) for measurements of surface strains and a linear variable differential transformer (LVDT) for interior stra…

Abstract Reliable test methods that provide reproducible results are essential for the mechanical characterisation and standardisation of textile reinforced concrete (TRC). This paper presents the results of an interlaboratory study comprising uniaxial tensile tests and bond tests on TRC with various textile configurations. All laboratories conducted the experiments in accordan…

Abstract Portland cement production accounts for about 9% of global CO 2 emissions, underscoring the need for alternative materials with a lower environmental impact. In this context, geopolymers emerge as a promising option, offering good mechanical performance, chemical stability, and a reduced carbon footprint. Among the residues with potential for geopolymer applications is…

Abstract Polymer-modified reclaimed asphalt pavement (PM-RAP) is increasingly available for recycling, but the complex ageing and degradation of styrene-butadiene-styrene (SBS)-modified binders hinder its effective reuse in surface layers. This paper aims to understand the chemo-morphological blending behaviour between aged PM-RAP binders and fresh polymer-modified bitumen (PMB…

Abstract Alkali-activated materials (AAMs) have emerged as a promising alternative to traditional cement-based binders. However, their adoption is restricted by non-user-friendly production processes, the need for curing at elevated temperatures when higher amounts of aluminosilicate sources are used and the limited availability or regional dependency of precursors and activato…

Abstract This study investigates the ageing behavior and performance trade‑offs of three bio‑based rejuvenators (namely, Anova, Sylvaroad, and Tall‑Oil Pitch (TOP)) in a 30% RAP binder system using a chemo‑mechanical framework combining Linear Amplitude Sweep (LAS), Multiple Stress Creep Recovery (MSCR) and Fourier Transform Infrared (FTIR). All binders were evaluated after sho…

Abstract Growing interest in the use of bio-derived materials in asphalt pavements is driven by their potential cost benefits and environmental sustainability. Among emerging technologies, hydrothermal liquefaction (HTL) has shown significant potential for converting wet biomass to bio-oil. This study evaluates the potential of bio-asphalt from HTL to partially replace conventi…

Abstract This research investigates the potential utilization of rice husk ash (RHA), an agricultural by-product, in lime-based mortars for the conservation of cultural heritage. While RHA has been extensively studied as a supplementary cementitious material in the construction sector, its application in lime-based mortars for the conservation of historic surfaces remains large…

Abstract The mechanical characterization of natural stone under varying moisture conditions is a critical issue for structural assessment, particularly when only non-destructive techniques are feasible. This study aims to characterize the Arroyo del Toro limestone and to establish reliable relationships between dynamic and static elastic moduli for application in finite element…

Abstract In 3D concrete printing (3DCP), achieving rapid development of high static yield stress after extrusion is critical to ensure buildability for preventing collapse of freshly printed concrete. Commonly, this is achieved by incorporating buildability enhancing additives during the initial mixing stage. However, high dosage of such additives often increases flow resistanc…
