This study aims to investigate and compare the interfacial bond characteristics between fire-damaged normal concrete substrate and ultra-high-performance fiber-reinforced concrete (UHPFRC) as a repair material.

First, fire-damaged normal concrete was prepared. Then, with a cast surface, the substrate was subjected to different surface moisture conditions. Three types of moisture conditions were set, namely, air dry, saturated surface dry (SSD) and wet. Slant shear and splitting cylinder tests were conducted to determine the interfacial bond strength of the composite.

In general, results indicate that surface moisture conditions significantly influence bond strength. The substrate under SSD condition exhibited the highest bond strength. The findings suggest that UHPFRC is a promising material for the repair and reuse of fire-damaged concrete structures.

This study compares the bond strength between fire-damaged normal concrete and UHPRC.

Based on the studies by Schelluch and Best et al., this study aims to investigate the existence of an audit expectation gap in Malaysia. The main motivation comes from the lack of research on the issue since the Enron and Andersen debacles. Besides, the Malaysian accounting environment has significantly improved since the 1998s reform, with the passing of the Financial Reporting Act and the establishment of the Malaysian Accounting Standards Board. The results indicate wide expectation gaps and misconceptions about audit in Malaysia. An experiment conducted among investors revealed the effectiveness of the use of reading material to educate users and correcting some misconceptions.
