ADVANCED HYBRID GEOPOLYMERIC FUNCTIONAL MATERIALS AND A PROCESS FOR THE PREPARATION THEREOF

摘要

The present invention relates to development of a novel advanced hybrid geopolymeric functional materials possessing very broad application spectrum ranging from cementitious materials to advanced functional materials due to their ' Inorganic -Organic Hybrid' matrix in contrary to the limited application of conventional geopolymeric materials due to their ' Inorganic matrix' only. The invention further relates to a process for the preparation of these materials. The process obviates the need of sodium silicate which is one of the main raw material, which is added externally in conventional geopolymerisation processes. Interestingly, in the present invention the sodium silicate has been synthesized in -situ by 'designing of conditions' for synergistic and simultaneous mechano - chemical reactions among the selected raw materials viz. industrial and agricultural wastes in alkaline environment. This results in the formation of 'Hybrid inorganic - organic frame work' of sodium silicate, which facilitates uniform dispersion of reacting species, thus resulting in the formation of homogeneous geopolymeric matrix with improved characteristics.
