Experimental evaluation of reinforced concrete columns produced with natural perlite aggregates under cyclic loading

open access: yesStructural Concrete, EarlyView.
Abstract A total of four reinforced concrete (RC) columns were tested to compare the structural capacities of RC columns produced by natural perlite aggregates and conventional concrete. The structural performance of the RC columns made from natural perlite aggregates was compared to conventional RC columns regarding the same concrete strength levels ...

Dimensional stability and water transport behavior of concrete with high contents of wind‐turbine blade waste

open access: yesStructural Concrete, EarlyView.
Abstract Fiber addition is a common strategy to enhance concrete's durability, avoiding cracks and reducing penetration of harmful agents. In this research, a sustainable fiber‐like material obtained from mechanical recycling of dismantled wind‐turbine blades and made up of glass fiber‐reinforced polymer (GFRP) fibers and microfibers, balsa wood, and ...

Dry mixes on the basis of reactive-powder concrete

open access: yesZaštita Materijala, 2022
This article presents the results of experimental studies of mortars based on dry mixes using reactive-powder concrete (RPC). This type of concrete can serve not only as the structural material in the construction of buildings and structures, but also as

Toward transparent AI: Predicting strength of fly ash foam composite concrete using explainable ML models

open access: yesStructural Concrete, EarlyView.
Abstract Fly ash foam composite concrete (FFC) is a sustainable, lightweight alternative to traditional concrete. However, accurately predicting its compressive strength (CS) through conventional laboratory methods is challenging due to its non‐linear behavior induced by the addition of foam content and fly ash. Also, the laboratory determination of CS

Performance of two‐to‐one non‐contact post‐installed lap splices

open access: yesStructural Concrete, EarlyView.
Abstract Post‐installed lap splices ensure the continuity of steel reinforcement in concrete‐to‐concrete connections by overlapping cast‐in (CI) reinforcing bars (rebars) with post‐installed (PI) rebars. Typically, the design of such splices follows provisions originally intended for CI lap splices, despite the differences in execution and bond ...
