ABSTRACT
Urbanization is a common problem especially in developing countries, as more and more poor people migrate to the cities. The basic building fabric in most of the dwellings and houses constructed by these people is earth. Earth is one of the oldest building materials known to man. Many techniques used today have changed little from early methods. Most of these methods make use of local resources, are labor intensive, and are logical and effective. However, it is a common knowledge that adobe buildings are not sufficiently resistant to the destructive action of nature, especially water. A research study was performed to evaluate pozzolanic mixtures that incorporate brick powder, lime and fly ash combinations for improving the mechanical and physical properties of adobe bricks and preservation of adobe walls. The test results showed that most of the mixtures are economical with adequate strength and durability.
