The eco-design of concrete, employing a hybrid binder (HB) and recycled aggregates (RA), stands as potential alternative for reducing CO2 emissions. This research assesses the impact three RA percentages HB/commercial CEM III/B binders on concrete formulations in terms technical performance (compressive strength (CS), carbonation (DC), chloride migration (DCl), transport properties. Results indicate that percentage is more critical variable than type binder. Life-cycle assessment from...
In this study, a hybrid alkali-activated ground-granulated cement consisting of 70% blast furnace slag (GGBFS) and 30% Portland (PC) activated with sodium sulfate was studied. Results were compared those blended system without an activator. The addition the activator significantly increased kinetics degree reaction these cements, particularly at early curing ages (2 days), leading to significant changes in phase assemblage. main product formed aluminum-substituted calcium silicate hydrate...
<title>Abstract</title> The RILEM TC 281–CCC ‘‘Carbonation of concrete with supplementary cementitious materials’’ conducted a study on the effects materials (SCMs) carbonation rate blended cement concretes and mortars. In this context, comprehensive database has been established, consisting 1044 mortar mixes their associated depth data over time. dataset comprises mix designs large variety binders up to 94% SCMs, collected from literature as well unpublished testing reports. includes...

<title>Abstract</title> Replacement of Portland cement is a practical strategy to reduce concrete manufacturing CO<sub>2</sub> emissions. However, this approach typically results in diminished portlandite content the hardened mix, elevating risk carbonation-induced corrosion steel-reinforced concrete. Carbonation frequently studied by exposing samples elevated levels ( 1% and 20%). carbonation process its by-products might differ markedly under natural conditions. In context RILEM TC 281-CCC...
