| Summary: | This paper reviewed with the research that was once initiated by Professor Dr. Joseph Davidovits where the term geopolymer was first applied to alkali aluminosilicate binders formed by the alkali silicate activation of aluminosilicate materials. The application of geopolymer had been one of the biggest founding where this product have been developed and continuously commercialized in during this few years. In this research, the functionality of geopolymer has been brought to another level where the physical properties and water absorption characteristics of geopolymer that is going to be used as a coating substance can be improved. Geopolymer will first be modified by reacting the standard geopolymer made up of fly ash and alkaline activator with lignin; commonly used in the paper pulp industries in the pulping process (pulping is the process which reduces wood to a fibrous mat by separating the cellulose from the lignin ). After the preparation of the lignin modifies geopolymer is complete, the paste will then be tested in term of the capability of the prepared paste to sustain water from penetrating the substrate (steel) which it is coating. The finding of this research will help to produce a coat of paste that can resist water thus increasing the durability of the steel. |
