REVIEW MENGENAI PENINGKATAN KUAT TEKAN BETON YANG TERKEKANG SECARA SEMPURNA DENGAN EKSTERNAL NATURAL FIBER REINFORCED POLYMER (NFRP)

Structural strengthening is needed in buildings that experience a decrease serviceability, inappropriate quality of existing concrete, and unexpected natural events such as earthquakes. One method has been widely used for structural external restraint using synthetic Fiber Reinforced Polymer (FRP). External restraints on concrete can significantly increase the strength ductility concrete. The use (FRP) material requires relatively expensive cost production process not environmentally friendly, so alternative Natural (NFRP) materials are renewable, cheaper, jute, hemp, cotton, abaca basalt. This research review aims to determine behavior confined with compressive due confinement. test carried out by providing an axial load object which restrained NFRP. NFRP specimens made wrapping entire circle fibers adhesives. results obtained from this several types basalt, it found type fiber number layers affect its strength. showed significant restraining effect increasing will (NFRP).
