Recycled Aggregate Concrete vs. High
Recycled aggregate concrete reduces environmental impact by incorporating crushed concrete waste but may exhibit lower compressive strength and durability compared to high-strength concrete , which provides superior load-bearing capacity and enhanced structural performance in columns. High-strength concrete typically achieves compressive strengths exceeding 50 MPa, making it ideal for demanding ...
Recycled aggregate concrete offers sustainable benefits by incorporating reclaimed materials but typically has lower compressive strength and durability compared to high-strength concrete . High-strength concrete for beams provides superior load-bearing capacity and enhanced performance in structural applications requiring increased durability and stiffness.
Review on high
Abstract High-strength recycled aggregate concrete (HSRAC) has been extensively studied in terms of mix design, properties, models, and structural behaviour. However, a comprehensive state-of-the-art review of HSRAC is still lacking.
At the cost of more cement in comparison to standard concrete , RAC from high-strength aggregates ( concrete and gres-porcelain tiles) may be used in r.c. structures. Some of its features, such as its low pH value and low compressive strength in the case of clay-originated aggregates , still need to be studied for an optimized mix design.

In this study, recycled aggregate (RA) derived from construction and demolition waste (CDW) was used to replace natural aggregate (NA) in new concrete , aiming to reduce reliance on natural resources. The researchers introduced a novel method combining mild acetic acid pre-soaking with mechanical grinding to enhance RA quality. They tested six variations of treated recycled aggregates (TRAs ...
In the context of sustainable construction, recycled concrete aggregates (RCAs), including both fine and coarse fractions derived from construction and demolition waste (CDW), are gaining traction due to their potential to mitigate environmental impacts by reducing reliance on natural aggregates and minimizing waste. This paper provides a comprehensive review of the effects of RCAs on the ...
Toward sustainable construction
To address these issues, the use of RA derived from C&D waste has gained considerable attention as a sustainable alternative in concrete production [4]. RAC is produced by partially or fully replacing natural aggregates with recycled materials obtained by crushing and processing waste concrete , masonry, and other construction debris [5].
Through appropriate mix design, the inferior performance in construction and structure of recycled aggregate concrete (RAC) compared with natural aggregate concrete (NAC) is controllable.
