improves the strength parameters of concrete, without causing significant deterioration of other parameters (water absorption, water permeability, frost resistance).
This section will discuss the studies, findings, and outcomes of previous studies on using high quality secondary raw materials in printable cementitious composites by pioneer …
High-quality concrete for infrastructure projects reduces maintenance immediately. Poor-quality concrete degrades over time, requiring frequent repairs that disrupt operations and increase …
One of the possible ways to reduce the environmental footprint and cost of the HPC/UHPC is to replace the powder or sand with secondary raw materials. In this study, the two types and three fractions of fine recycled concrete aggregate (fRCA) are used as supplementary materials in HPC.
The Eccentric Rotor Crusher (ERC) uses high pressure from an eccentric rotor to break down concrete, which improves aggregate quality but uses more energy and produces higher CO 2 emissions than ORC. The Compression and Impact (C&I) combines compression and impact forces to crush concrete.
In this paper, steel grits are used for impact crushing of waste concrete to produce high-quality RCA. The effects of impact velocity, impact time, and concrete strength on mortar …

In particular, recycled concrete aggregates show a better quality and homogeneity than mixed recycled aggregates that make them more suitable for concrete. This work presents an overview on the influence of recycled aggregate quality on the physical, mechanical and environmental properties of concrete.
Extremely large production of concrete, with 25 billion tonnes produced annually at the global level, 4 causes the following major environmental impacts: large amount of produced CDW (mostly inert and non-dangerous …

This section will discuss the studies, findings, and outcomes of previous studies on using high quality secondary raw materials in printable cementitious composites by pioneer researchers.
High-quality concrete for infrastructure projects reduces maintenance immediately. Poor-quality concrete degrades over time, requiring frequent repairs that disrupt operations and increase costs. Better concrete formulae use cutting-edge technologies to resist corrosion, cracking, and other degradation. Early quality investments reduce downtime ...
This paper compares the use of jaw and impact secondary crushing for producing coarse recycled aggregates from concrete wastes, obtained from road pavement and demolished building materials.
This research investigates the potential of utilizing recycled concrete aggregate (RCA) and recycled sand (RS), derived from crushed concrete cubes, as sustainable alternatives in construction materials.
In this paper, steel grits are used for impact crushing of waste concrete to produce high-quality RCA. The effects of impact velocity, impact time, and concrete strength on mortar liberation are mainly studied.
