Utilizing recycled aggregates (RAs) in concrete production represents a promising path toward sustainability; however, it often results reduced physical and durability properties. The weak interfacial transition zone (ITZ) the adhered mortar aggregate (RAC) contribute to lower mechanical strength limit its application demanding environments. This study investigates an accelerated carbonation technique enhance properties of RA RAC. Recycled aggregates, with particle size 10–20 mm, were subjected at 1 bar for 2 h controlled chamber. Results demonstrate substantial improvements compressive split tensile strengths carbonated (CRAC), increases 30% 42% compared conventional RAC, respectively. CRAC mix also exhibited 1.5% increase dry density water absorption (6%) RAC (7.58%). After 90 days acid exposure, reductions 48.85% 37.9% observed mixes, respectively, from their 28-day strength, while weight loss was limited 5.4%, 10.92% In sulfate exposure tests over 150 days, showed 31.4% 19.7% losses 3.6% 2.2%, indicating enhanced resistance harsh However, blended supplementary cementitious materials (SCMs) diminished properties, likely due alkaline environment caused by rapid calcium hydroxide pores during carbonation. Overall, findings highlight practical potential improve performance offering viable pathway sustainable construction applications.

Research on the combined substitution of supplementary cementitious materials (SCMs) has already demonstrated that it might be one few viable options to produce low-carbon concrete at scale. This paper presents an experimental investigation performance and durability rice husk ash (RHA) calcined clay (CC) in ternary blended exposed chloride attacks under wet/dry cycles. Portland cement (PC) was replaced by RHA CC up 50% weight concrete. Samples were subjected cycles 3.5% NaCl water, with mineralogical composition microstructure development before after exposure analysed TGA-DSC, MIP, XRD, SEM. The against investigated terms compressive strength, water absorption, open porosity, density, thermal conductivity, electrical resistivity. results showed mixes 60% exhibited increase 33% followed minimal changes absorption. While a decrease resistivity measured all samples CC, increasing content resulted improved resistance penetration. Increasing more refined microstructure, overall porosity 32% compared control series. alone did not contribute significant improvements cycles, SCM replacement levels improvement hardened properties durability. provides valuable insights into long-term strength innovative
