Sebagai satu peraturan kebiasaan, ikatan antaramuka struktur konkrit lama dengan lapisan baru bahan baik pulih merupakan salah satu faktor penting untuk memastikan struktur berfungsi dengan baik, selamat serta tahan lasak. Oleh itu, untuk meningkatkan rintangan terhadap penetrasi bahan-bahan yang merosakkan, satu ikatan yang baik dan efektif di perlukan antara permukaan _struktur konkrit berkenaan. As a rule of thumb, the interfacial bonding between old concrete structures with a newly overlay repair material is one of the most important factors for structural functionality and safety as well as durability performance. In order to acquire an enhanced resistance against penetration of harmful substances, a good and effective bonding is necessary at the concrete interfaces. The objective of this study was to examine experimentally the mechanical properties and permeability characteristics short term and long term of the interface performance between normal concrete (NC) substrate which represented old concrete structures and an overlay of ultra high performance fiber concrete (UHPFC) as a repair material.
