The optimum percentage of Metakaolin that produces the maximum increase in strength was also determined. The second part of the study sought to increase the toughness of concrete by the addition of fibers. Different fibers were added to concrete and a comparative study was conducted. It was seen that all of the fibers seemed to increase the toughness and ductility of concrete to varying degrees. In the third part of the study the effect of using different forms of external confinement on the load-deformation response of concrete was studied.
External confinement consists of confining concrete in a casing of a tough material such as plastic.
Tests performed on confined concrete seemed to show a marked increase in ductility and strength when compared to normal concrete. Testing is absolutely essential to understand any material s behavior. The fourth part of the study addressed various types of testing techniques which are available and are currently used to test concrete. The different testing techniques were assessed to determine which technique was most suitable to obtain the load-deformation response of concrete. HTML coding was used to create tables and many other aspects of the page which makes it cutting edge.
