The role of materials in construction work is so significant because from findings, materials compromise seems to have contributed greatly to collapse of buildings than any other factors. It was noted in the UNCHS-United Nations Center for Human Settlements that of all the inputs in construction, about 50% to 80% account for building materials. Therefore, materials in the building industry cannot be over emphasized by saying that professionals’ searchlight should, however, at all times be on the quality of material input in the construction industry.
Construction Materials are very essential and should be critically looked into so that they could be sustainable to meet current needs and without impairing on the future and still be able to meet the said future need. The two main categories of materials are Natural and Man-Made.
- Coarse or fine aggregates.
Man-Made Materials such as
- Blocks or Bricks
- Concrete and etc.
Building materials constitute the highest percentage of input in the building components and taking into consideration all elements or components that make up a building in terms of cost, the cost of materials alone in relation to all other elements, ranging from equipment, labour, finance, administration, space and acquisition is humongous and takes the largest share in percentage.
Unarguably, the use of substandard materials in construction work is one of the main causes of building failure. Building failure or collapse happens both in the developed and developing countries but the rate of occurrence in the developing country such as Nigeria is quite alarming and therefore call concern. The roles of these materials are so vital that they contribute immensely to the collapse of buildings. It is rather unfortunate that both human and economic loss recorded each time there is a failure or building collapse is rather humongous. Building materials such as reinforcing steel, cement, sand, granite, sandcrete blocks and concrete play huge important role in either the collapse or stability of buildings in Nigeria.
Construction materials must be carefully selected before the design is completed. It is very important to further ascertain the quality of materials to be employed juxtaposing it with the approved design. Test on materials should also be carried out to further ascertain the quality of materials to be used in the building construction to be embarked upon.
