The concept of eco-materials was introduced to encourage the development of materials that are harmless to the global environment, make an efficient use of raw materials and are recyclable. A research programme to develop unique types of eco-materials from municipal solid waste ash (MWA) and natural materials (anthill, quarry dust, high-silica pit sand, diatomite, burnt brick) found in Kenya is described. The programme investigated the potential of MWA and natural materials as a partial replacement of fine aggregate in concrete and as a partial replacement for cement. It also assessed the performance of the eco-cement for concrete production. The incorporation of up to 15% of MWA in concrete increased the strength of the concrete. Incorporation of natural materials also increased the compressive strength of mortars.
