Description
Summary:This paper presents research work done on the applicability and viability of geopolymer technology on the various types of soils present in Kenya. The main aim is to provide an alternative building material to the conventional materials available in Kenya. Stone Mining activities in Kenya have generated a lot of aluminosilicate waste that can be a good source of raw material for geopolymer synthesis. Geopolymers are amorphous aluminosilicate materials whose synthesis occurs in a fast chemical reaction. The proposed mechanism occurs in three stages, the dissolution of Al and Si present in the source material, the condensation of precursor ions into monomers and the polymerization of monomers into polymeric structures. For the reaction to result to a geopolymer the ratio of Si and Al is paramount. Structural characterization of the soil samples and the developed building blocks were done using Shimadzu FT 8000 FT-IR spectrophotometr, X-RF.
