Pozzolanicity, Chloride Ingress and Compressive Strength

There is an inherent desire by most Kenyans to own decent and affordable houses. On average, the cost of building materials for a housing structure comprises about 50 percent of the total cost of the building. The high cost is normally attributed to the high prices of cement. A majority of the Kenyan population cannot afford cement, which is a major building binder for housing and construction in general .This has lead to the mushrooming of slums such as Kibera in Nairobi-Kenya. There is an increasing demand for decent housing as the shanty houses poses various health challenges. Blending of OPC and local clays to make potential pozzolanic cements could offer affordable cement. The blended cement could lead to better housing facilities for low income earning people in the developing countries, Kenya included.
