Fiber Reinforced Polymer as a Reinforcing Material for Concrete Structures

Abstract

Concrete is one of the materials that is widely used in various structural works because it has advantages, especially it has high compressive strength and is easy to form. However, concrete can also be damaged by physical, chemical, mechanical and excessive loads. Damaged concrete structures must be repaired and strengthened immediately to prevent further damage that can lead to structural failure. One of the materials that can be used for structural reinforcement is Fiber Reinforced Polymer (FRP). FRP is a composite material made of three basic components, namely fiber, polymer and additives. FRP has advantages such as having high strength, light weight, corrosion resistance, easy installation, requiring little or no scaffolding. FRP is very well used to increase the capacity of structures in buildings that are undergoing changes in function

Cracks in Reinforced Concrete Beam

“…Retak yang terjadi pada beton bertulang sangat mempengaruhi kinerja tulangan. Jika retak sampai tulangan akan menyebabkan terjadinya delaminasi (lepasnya selimut beton dari struktur pelat beton akibat baja tulangan mengalami oksidasi) dan spalling (terkelupasnya permukaan beton akibat korosi baja tulangan atau tumbukan) (Layang, 2021a).…”

Analysis of the Resistance of Self-Compacting Concrete (SCC) with the Use of Granite Stone Waste to Alkali-Silica Reaction

“…Pillars are the lower structure of the bridge which is located underwater for a long time that possible to fail due to aggregates that react with cement to form silica gel. According to Layang [3], the reaction of alkali in cement and silica content (SiO2) in aggregates is known as the alkali-silica reaction. The chemical reaction between the alkaline hydroxides of cement paste and certain silica-containing minerals produces a hygroscopic gel that absorbs water and expands in the presence of moisture [4].…”
