CORROSION OF CEMENT PASTE In general terms cement products have good durability‚ but their strength will decrease or even damage structures with the role of some erosive media (such as soft water‚ acid water)‚ known as the erosion of cement paste. The main reasons for corrosion are: Soft-water Corrosion (Dissolution Corrosion) Rain‚ snow‚ distilled water‚ industrial condensate water‚ and the river water and lake water with low bicarbonate content‚ all of them belong to soft water. When hardened

Affecting the Rate of a Chemical Reaction Title of your investigation An investigation into the factors affecting the rate of a chemical reaction 1. Aim of investigation To investigate the major factors that affect the rate of corrosion. 2. Motivation (explain why you have chosen to investigate this particular topic) I have chosen to examine this experiment as it applies to our daily lives. Rusting of metal occurs every day whether it’s the nails on our deck or that rusting bicycle

in rust and corrosion when dipped in different solutions. Corrosion is the reaction between a metal and it’s surrounding environments. Corrosion occurs when a metal (for example Copper) and different environments (such as water‚ air‚ acids‚ bases‚ etc.) come into contact. Corrosion is the act of deterioration in metals.[1] A chemical reaction occurs between the metal and it’s environments Eg. Copper + Oxygen ( Copper Oxide Cu (I) + O ( CuO Rust is very similar to corrosion but only occurs

Introduction Gravity is a force that pulls all objects on Earth to its surface at a rate of 9.8m/sec. Gravity is an acceleration of a free falling object (Encyclopedia Britannica‚ 2014). Gravitational potential energy (Egp) is a concept from the law of gravity. As an object is positioned with a gravitational field‚ the object can store energy which is called gravitational potential energy (Physicsclassroom.com‚ 2014). As the object begins movement or work the energy transfers into kinetic energy

Germination in plants is the process in which dormant seed begins to grow and sprout under certain growing conditions. The English pea‚ also known as the garden pea‚ is a member of the legume family and is known to grow roughly three to four inches long. Research shows that it only takes approximately 1 week for the seed to start to germinate. There are many things that can affect‚ the growth of the pea seed such as; temperature‚ moisture‚ planting depth and sunlight. The pea grows best in temperatures

Biology EEI Overview By Jack Chappell Introduction: The most common fungi in the world is Bread Mold Fungus‚ also known as Rhizopus stolonifer (NCBI database). This mold is a common problem in most households throughout the world. The experiment being undertaken‚ changes the ingredients in bread to test the rate in which mold grows differently. These results will also be accommodated with climate control and the effects that could be associated with temperature and humidity. Mold will

This research paper is concerned with the effect of the pre corrosion on the mechanical properties‚ fatigue life‚ microstructure and weight density of Aluminium alloy 8011. 3.5 % NaCl solution was used to pre corrode the Aluminium alloy 8011 specimens. The specimens were kept in the solution for 100 hours. After the pre corrosion various test were performed to study the effects of pre corrosion on tensile strength and fatigue life. Aluminium alloy 8011 is used in the production of fins of various
