Abstract

Growth of the world’s population is projected to add 2.5 billion people to the urban population by 2050, with nearly 90% of the increase concentrating in Asia and Africa. This will result in an immense demand for urban concrete infrastructure, leading to more global anthropogenic carbon-dioxide emissions. The most promising strategy for Africa entails the partial substitution of Portland cement clinker with additions of kaolinite clay and limestone to make cement and concrete. Kaolinite content is an important indicator of clay suitability. Results obtained by X-ray fluorescence, X-ray diffraction and thermogravimetric analysis indicate the potential of clay from two South African sources for clinker replacement in cement and concrete, showing that one source is very suitable, while the other is not.
