Influence of hydraulic jigging of construction and demolition waste recycled aggregate on hardened concrete properties

Revista IBRACON de Estruturas e Materiais, 2021
: Concern with the maintenance of natural resources has increased research about recycled aggregates for concrete production. However, the heterogeneity of recycled aggregates is one of the main constraints for their use in practice, because it can ...

Durability parameters of reinforced recycled aggregate concrete: Case study [PDF]

, 2019
Recycled concrete aggregate (RA) from pavement demolition was used to make concrete. Ten concrete mixtures with different replacement percentages of RA (coarse and fine) were made.

Physical-chemical and mineralogical characterization of fine aggregates from construction and demolition waste recycling plants [PDF]

, 2013
Construction and demolition waste (CDW) represents around 31% of all waste produced in the European Union. It is today acknowledged that the consumption of raw materials in the construction industry is a non-sustainable activity.

Experimental and micromechanical investigation on the mechanical and durability properties of recycled aggregates concrete

Cement and Concrete Research, 2019
In this work, we conducted an experimental and micromechanical investigation on the mechanical and chloride diffusion properties of recycled aggregates concrete (RAC). Due to the composite aspect of the recycled concrete aggregates (RCA), their impact on

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Freeze-thaw durability of recycled concrete from construction and demolition wastes [PDF]

, 2017
Road engineering is one of the most accepted applications for concrete including recycled aggregates from construction and demolition wastes as a partial replacement of the natural coarse aggregates.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Physical and mechanical behaviour of recycled concrete under destructive and non-destructive testing

Budownictwo i Architektura
Aggregates recycled from construction sites may exhibit slightly inferior characteristics compared to natural aggregates in terms of porosity, friability, and variability.
