ABSTRACT
The vast and varied coastal states with the highest population growth, wherein lives 70% of humanity with diversified natural resources, looks forward at the beginning of the twentieth century for real
technology wisely, need to comprehend the lessons of their predecessor’s examples in Europe, America and more recently Asian development. As an estimate, by 2050 more than 75% of the world population will live in coastal areas. To meet and serve these frequent and far reaching changes, large quantities of materials are required for construction of shelters and infrastructure. Concrete, for obvious reasons, lends itself as the only feasible material capable of meeting these needs. In general, the developing countries in coastal states are consuming about one third of the concrete produced annually, although these countries make up 85% of the coastal states population. If the consumption trends and over consumptive life style being followed in the industrialized coastal countries are to be imitated in the developing coastal state countries, the world will become unsustainable. The amount of materials needed for decent living is unimaginable.
