The deep soil with a relatively poor compressive strength has been an issue for the researchers and constructors for years since the hardships faced by them when trying to construct heavy structures on top of them. It is found that weak soils like those can be strengthened by adding different additives. Cement is commonly used for the above purpose but, since it's expensive to use alone, cement mixed with fly ash was tested with different soils to strengthen them. The aim of the research was to find out the increase/decrease of strength when two different cement and fly ash mixtures were mixed with three different types of soils common in Malaysia in different proportions and to find the optimum percentages of each mixture to be mixed with each soil to obtain a desired strength. The Modified Standard Proctor test and the Unconfined Compressive Strength (UCS) tests were carried to study the behaviour and strength of the soils when mixed with the above additives.
