Abstract

The need to utilise local materials for the building industry in developing countries cannot be over-emphasised. Lateritic soils are abundantly available in the tropics and can be used for the manufacture of durable bricks. This paper reports on improvement of the strength of these bricks by addition of cement. Results show that to achieve optimal strength conditions, the soil-cement bricks require much less hard firing than plain bricks. Depending on the firing temperature and amount of cement used, the addition of cement could result in brick strengths of up to four times those with no cement added at the same temperature and at least two and a half times the maximum strength with plain bricks at any firing temperature.
