wire mesh as a free edge’s reinforcement‚ the hairpin rebars are positioned in the 2nd phase‚ as shown in the first figure. 2. The alternative solution for providing the free edges’ reinforcement includes the formation of hooks at the ends of the upper and lower rebars as shown in the second figure. This solution compared to the hairpin solution‚ apart from everything else‚ has a higher shaping-cost but mainly it lacks a natural peripheral rebar chair. The reinforcement of a solid raft foundation

The rattle of machine gun fire filled the air as the raiders hid behind a heavy steel desk. Sparks fell on Pierce’s head as bullets hit the desktop and walls. When the clicking of empty mags sounded‚ the raiders opened fire at the vault guards. As the last guard fell‚ Pierce and his comrades went deeper into Vault 408. On the way the raiders picked up supplies‚ guns‚ and valuables. Once the cryo room was reached‚ a scarred man with a brown mohawk began directing the raiders. The man‚ Rik‚ was the

“We’RE raising the BAR.” This is Steel Asia Manufacturing Corporation’s marketing tagline to showcase their sole product – rebars. Rebars are cylindrical bars of steel used by the construction industry for building the structures of every building‚ house‚ road‚ or project that they do. The experience at Steel Asia Manufacturing Corporation exposed me to the steel manufacturing industry. The said field trip was not only very educational; is also filled with fun. As a future chemical engineer of

methods provided a qualitative as well as a quantitative view of the carbonated portions. The results illustrated a significant change in the structure of the carbonation profiles after the re-alkalization process. However‚ repassivation of the steel rebars could not be demonstrated. Keywords: Re-alkalization‚ Carbonation‚ pH INTRODUCTION Steel bars in reinforced concrete are protected from corrosion by the highly alkaline environment inside the concrete (pH≈13). If the pH decreases in the environment

Table of Contents Background Information Basic Information It will be useful if we can determine the cover or distance of the reinforcement from the nearest concrete surface of the structure without destroying or cutting the member. A large number of attempts have been made but only the method involving electromagnetic principles has been successful. (Rao‚ 1949) How a Cover Meter Works? The change of inductance of an iron cored inductor known as ‘search unit’ due to the proximity of the

1. INTRODUCTION 1.1 Background The report will mainly focus on the differences between reinforced‚ prestressed and partially stressed concrete. These concrete reinforcing methods differ in the period they have been used. Reinforced concrete was developed by a nursery owner in Paris in 1867‚ Joseph Monier‚ applying it to practical use for the first time (Salmon & Wang‚ 2007). Prestressed concrete’s discovery dates back to the late 1800’s. Freyssinet was one of the first engineers who used
