Evaluation of the contact characteristics of graded aggregate using coarse aggregate composite geometric indexes

Construction and Building Materials, 2020
The influence of the aggregate’s geometric properties on its contact characteristics was investigated by testing the geometric parameters of three aggregates types using the aggregate imaging system (AIMS).

Flexural behavior of precast, prestressed, lightweight aggregate concrete-conventional concrete composite beams

Construction and Building Materials, 2021
This study explores the flexural behavior of precast, prestressed, lightweight aggregate concrete-conventional concrete composite beams. Ten specimens were tested with consideration of the height of the combined interface, the reinforcement ratio, and ...

Compressive and flexural properties of ultra-high performance fiber-reinforced cementitious composite: The effect of coarse aggregate

Composite Structures, 2020
The inclusion of coarse aggregate in the cementitious composite can improve the mechanical property and simultaneously curb the cement demand thus lowering the production cost in concrete built infrastructure.

Long-term behavior of continuous composite slabs made with 100% fine and coarse recycled aggregate

Engineering Structures, 2020
A composite slab is an efficient modern structural member. Recycled fine and coarse aggregates are alternative green materials for the depleting natural sand and natural gravels in the composite slabs.

Influence of aggregate surface treatment on corrosion resistance of cement composite under chloride attack

Construction and Building Materials, 2020
The high porosity of interfacial transition zone (ITZ) could significantly influence the durability of offshore concrete structures. This study aims to investigate the effects of aggregate surface by coating slag and silica fume on the ITZ microstructure,

Assessment of PCM/SiC-based composite aggregate in concrete: Mechanical, physical and microstructural properties

Construction and Building Materials, 2020
This study used PCM/SiC-based composite aggregates made using slag aggregate, paraffin wax, and silicon carbide. Concrete samples were prepared by replacing natural coarse aggregates with PCM/SiC-based composite aggregates at various replacement ratios ...

On aggregate composite indicators

Journal of the Operational Research Society, 2017
In this paper it is shown that the unweighted arithmetic average is the theoretically consistent scheme to aggregate composite indicators, derived from the benefit-of-the-doubt model, across decision-making units.

Optimization of dye-contaminated wastewater treatment by fungal Mycelial-light expanded clay aggregate composite.

Environmental Research, 2023
Dye-contaminated wastewaters from the printing batik industry are hazardous if discharged into the environment without any treatment. Finding an optimization and reusability assessment of a new fungal-material composite for dye-contaminated wastewater ...
