Water absorption and saturated surface dry density (SSD) are two decisive properties that define the quality of aggregate. The high absorption of mixed recycled aggregates must be taken into consideration in concrete mixing, due to the fact that part of the water added in the mix will fulfil the accessible pores of recycled aggregates, thus …

Aggregate is an important raw material in the infrastructure construction industry. Aggregate is divided into fine aggregate (commonly known as sand, with a particle size between 0.15-4.75mm) and coarse aggregate (commonly known as stone, with a particle size between 4.75-9.0mm).. The aggregate material is loose and granular in shape and …

These aggregates present a relatively low density, classifying them in the category of LWA. This weight reduction is due to the high porosity of these aggregates, suggesting a significant capacity of water imprisonment for the hydration of cement. Moreover, after carbonation the percentage of porosity and water absorption decreased, …
