COMMON SYNTHETIC PLASTICS

INRODUCTION
Plastic molecules are made of long chains of repeating units called monomers. The atoms that make up a plasticâ„¢s monomers and the arrangement of the monomers within the molecule both determine many of the plasticâ„¢s properties. Plastics are one of the classification of polymers .If a polymer is shaped into hard and tough utility articles by the application of heat and pressure ,it is used as plastic.
Synthetic polymers are often referred to as plastics, such as the ....etc

PROTECTIVE COATINGS FOR CONCRETE BRIDGES



Protection of structures is very important for increasing the life of the structure. There is a growing national concern about premature deterioration of our concrete infrastructure projects such as bridges, aqueducts etc. requiring early repair and/or replacement. Use of protective coatings will increase the durability and hence the life of these structures. As most of these structures are made up of concrete and steel, the role that coatings play in protecting the s ....etc
