Abstract

This article presents the results of a research project that aimed to evaluate how the number of fiber-reinforced polymer (FRP) layers and the compressive strength of concrete affect the stress-strain behaviors of concrete columns produced from artificial lightweight aggregate with square cross-sectional shapes. Eighteen test specimens were manufactured and wrapped with glass fiber-reinforced polymer (GFRP) material. The specimens were later subjected to concentric compression for experimental evaluation. The experimental results suggest that GFRP efficiently confines square lightweight aggregate concrete columns. Furthermore, the test results indicate that adding FRP layers augments the ultimate stress and strain. Finally, the results suggest that an increase in the compressive strength of concrete leads to a corresponding increase in the ultimate stress. On the other hand, it has been observed that the ultimate strain decreases as compressive strength increases. The research findings reveal the behaviour of FRP-confined square lightweight aggregate concrete columns, which may also be utilized to formulate a new design-oriented model for these columns.

Abstract

Penelitian ini bertujuan untuk menilai efek dari penggunaan campuran antara pasir sungai dan pasir ringan buatan serta pasir ringan buatan yang telah dihaluskan dalam campuran beton yang terbuat dari kerikil ringan buatan. Parameter yang ditinjau adalah adalah berat dan kuat tekan beton. Delapan belas buah benda uji dengan target kuat tekan 15, 28, dan 41 MPa dibuat dan dites pada saat berumur 28 hari. Hasil penelitian ini menunjukan bahwa beton yang dibuat dengan menggunakan pasir yang merupakan campuran antara pasir sungai dan pasir ringan buatan dapat digolongkan sebagai beton ringan. Demikian juga hasil penelitian ini menunjukan bahwa berat beton yang dibuat dengan menggunakan pasir ringan buatan tanpa dicampur dengan pasir sungai memiliki berat yang jauh lebih ringan dari beton yang terbuat dari campuran antar pasir ringan buatan dengan pasir sungai tetapi memiliki kuat tekan yang hampir menyamai beton yang menggunakan campuran antara pasir ringan buatan dan pasir sungai.

Abstract

This paper describes the findings of a research study aimed at evaluating the impact of various parameters on the stress-strain behavior of concrete composed of artificial lightweight aggregates with rectangular cross-sections. The factors that were evaluated include the number of fiber-reinforced polymer (FRP) layers, the compressive strength of the concrete, and the cross-sectional shape of the concrete. A total of twenty-two test specimens were fabricated, wrapped with Fiber Reinforced Polymer (FRP), and subjected to concentric compressive loading for experimental evaluation. The experimental findings indicate that Fiber Reinforced Polymer (FRP) demonstrates an excellent wrapping technique for lightweight concrete composed of lightweight aggregate. In addition to this, the test findings indicate a positive correlation between the number of fiber-reinforced polymer (FRP) layers employed and the resultant ultimate stress and strain shown by concrete composed of artificial lightweight aggregate. The test results additionally demonstrate a clear relationship between the rise in ultimate stress and the compressive strength of concrete, while showing an inverse relationship with the ultimate strain observed. Similarly, the test results indicate that the utilization of Fiber Reinforced Polymer (FRP) wrapping has more efficacy when applied to round cross-sectional shapes as opposed to rectangular cross-sectional shapes.
