||The purpose of this study is to develop indigenous local materials that were being used as building materials in the Senegambia and Mali region but now facing out due to the use of preferred modern materials. Interest in the indigenous materials used for building construction in Senegambia is the driving force behind this study. This whole thing started when I asked myself why many old buildings that date for centuries are absent in the Senegambia region unlike other places like Egypt and Ethiopia for example. The search for this answer lead into the discovery of some problems of the building materials used in the olden days of this region. The thatch for instance used in roofing decays with time while the adobe walls are weakened when comes in contact with moisture/water.
A study of the processes involved in both the modern and old methods of building construction in Senegambia concerning the materials used on both eras is done to ascertain the strengths and weaknesses of both methods. This would then be followed by systematically merging the strengths of both methods and eliminating their weaknesses, hence a new method would emerge and that would be the proposed method/system of this study. This new system of building construction for Senegambia is known as Rammed Earth Concrete (R.E.C).
It is eminent that building materials that are friendly and harmless to the environment are highly needed in this modern era. Moreover, these indigenous building materials are cheaply and freely available in abundance. Their use in today’s construction system would prove to be a cost cutting mechanism when compared with the materials being used currently for building construction purposes in Senegambia. Therefore, their efficient use in today’s modern time would go a long way in cutting down building construction costs, thereby making it easier for poor members of the society to easily build houses for themselves. Below is a summary of the findings of this study.
Continuous supply of the building construction materials for the proposed system is guaranteed since they’re freely abundant and their extraction from nature does not cause problems to the environment.
2. The indigenous materials to be used for the R.E.C system are very cheap and would keep construction costs low.
The building construction materials to be used for the R.E.C system can be recycled and reused over and over.
