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

Rain on Building Materials Question: What is the effect of 6M sulfuric acid (H2SO4) on the corrosion rate of the 3 grams of steel as the amount (number of sprays) of sulfuric acid increases? Variables: Independent variable: the number of sprays of 6M sulfuric acid (0‚ 5‚ 10‚ 15‚ 20‚ 25 times) to observe its effect on the corrosion rate. Each spray will contain about 10mL. Dependent variable: The corrosion rate. It will be calculated by measuring the mass of steel after leaving it for one day.

failure of an aircraft due to aging are briefly discussed as following. (a) Metallic Corrosion. The deterioration of the surface of a metal due to a chemical reaction is called metallic corrosion. This occurs because metals come in contact with electrolyte mostly contaminated water. As it arises‚ it may go undetected and result in loss of integrity of metallic structures. Since metallic corrosion is directly related to structural integrity‚ there is a dire need to look into the ground environment

plutonium and thorium are possible energy sources. To protect the environment from radioactivity‚ the fuel is cladded. For the cladding is usually zirconium alloys or stainless steels used because it should be able to let the neutrons pass and be corrosion resistant. This cladding has also the advantage to give strength to the rod. The reaction in the nuclear reactor is controlled with control rods. These control rods should be able to absorb the neutrons‚ so cadmium and boron are most of the time

Alnico magnet alloy is largely comprised of Aluminum‚ Iron‚ Cobalt and Nickel. Alnico is a moderately expensive magnet material because of the Cobalt and Nickel content. Alnico magnet alloy has high maximum operating temperature and a very good corrosion resistance. Some grades of Alnico alloy can operate upwards of 1000C. Magnets made with this alloy are available in a variety of grades and dimensions and they are usually cast. Alnico magnet material is an older technology and it has a rather low

Aloha Airlines Flight 243 Boeing 737-200 April 28‚1988 Honolulu‚ HI Aloha 243 was a watershed accident : There were very clear precursors that were not acted upon It reflected a basic lack of airplane level awareness It pointed out errors in basic design and certification philosophies There were catastrophic unintended effects April 28‚ 1988‚ Flight 243 was scheduled for several “Island-hopping” flights: First Officer conducted preflight inspection in darkness and noted nothing unusual Airplane

with Atomic Number 29‚ has been extensively used for thousands of years because of several primary properties that have dictated its use throughout history. Among them we can count durability‚ strength and‚ as a semi-noble metal‚ good resistance to corrosion. With a hardness of 3 on the Mohs scale‚ pure copper is relatively soft and malleable‚ which makes it an easy metal to work with. Analyses of artefacts from lithic civilizations have shown that native copper had not only been hammered‚ but annealed

First the total volume of gas that is to be stored needs to be calculated. From the mass balance it is known that 30.92 kmol of methane can be expected every hour. This correlates to 742.0 kmol/day. The ideal gas law will be used‚ with a compressibility factor‚ Z‚ to account for departure for un-idealality. An operating temperature of 50 will be assumed‚ as this is the highest feasible ambient temperature that can be expected. Also assume that the pump or compressor used to transport the methane
