The Apparent Thermal Conductivity of Pozzolana Concrete

Physics Procedia, 2011
AbstractThe recent development of some lightweight construction materials, such as light concrete, can play an important role as an insulator, while maintaining sufficient levels of mechanical performance. The quality of insulation to provide depends on the climate, the exposure of the walls and also the materials used in the construction.

Influence of Granite Powder Waste on the Flexural and Microstructure Morphology Behaviors of Reinforced Concrete Beams With Glass Fiber Reinforced Polymer Bars

Engineering Reports, Volume 7, Issue 8, August 2025.
This study presents an empirical investigation into the flexural characteristics of concrete beams that are reinforced with glass fiber‐reinforced polymer (GFRP) bars, as well as concrete beams reinforced with traditional steel reinforcements with partial replacement of fine aggregate by granite powder.

Coupled Paleomagnetism and 40Ar/39Ar Dating of Latera Ignimbrites (Vulsini Volcanic District, Italy) Unravel Processes Associated to Piston‐Collapse Calderas

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Correlation of ignimbrite units at polygenic calderas is mandatory for the reconstruction of caldera‐forming events and proper identification of their eruption dynamics. However, ignimbrites erupted at different times from the same caldera can display similarities in composition and lithology that can hamper proper correlation of outcrops ...

Application of low‐emission cement CEM II/C in concrete made with low‐effort processed recycled aggregates

Structural Concrete, Volume 26, Issue 3, Page 2881-2899, June 2025.
Abstract The present study investigates the applicability of recycled concrete aggregates (RCA) for use in structural concrete made with low‐emission cement CEM II/C‐M (global warming potential of 377 kg CO2,eqv.). The aim is to show the potential of RCA processed with minimal energy, water, and economic expenditure.
