  • Patent number: 10262764
    Abstract: The conventional radiation shielding materials are made using lead, barite and hematite ore which are either toxic, costly and are non-replinshable possessing limited functionality. In view of above, we develop a novel process for making advanced non-toxic Red Mud based functional radiation shielding materials utilizing appropriate novel matrixes like Advanced geopolymer, geopolymeric-polymeric matrix, putty, cement and phosphatic based matrix and are also compatible with conventional matrixes. The appropriate physico-chemical consolidation and or densification of red mud using advanced or conventional matrix helps in obtaining functional radiation shielding material by simultaneous and synergistic chemical reactions among various mineralogical and chemical compounds of red mud with complementary various chemical compounds present in citrus fruit peel waste especially citric acid to form nano gel material to obtain the fine “tailored shielding powder”.

  • Patent number: 10165713
    Abstract: Conventional shielding materials are based on single material either toxic lead or barium based compounds and any matrix made therefrom contains only single phased barium based compounds, thereby posing limited radiation shielding capacity. Since brine sludge, an industrial toxic waste product, generated in chloralkali industry contains multiple compounds; there is a need to provide a process which enables the preparation of multi-phase based radiation shielding materials. In view of the above, the present invention provides advanced non-toxic radiation shielding materials utilizing tailored brine sludge and a process that enables conversion of toxic elements like chromium, zinc, copper and vanadium present in brine sludge into non-toxic shielding phases, thereby enabling to convert a toxic waste material into highly value added advanced radiation shielding materials possessing homogeneous radiation shielding matrix.

  • Patent number: 10023497
    Abstract: The present invention relates to a novel multifunctional material for workability of geopolymeric system and its process thereof. The viscous characteristics in geopolymeric system are responsible for observed negligible workability of geopolymeric cement concrete system and which limits its broad application spectrum. The novel multifunctional material of the present invention prepared by digestion of siliceous agricultural waste i.e. Rice husk with aqueous alkaline materials involving simultaneous and synergistic chemical reactions among the various constituents of rice husk, aqueous alkaline compounds and optionally adding Cetyl trimethyl ammonium bromide (CTAB) to obtain in-situ synthesis of desired nano-sized multi functional agents lignin, hemicelluloses, cellulose, sodium silicate necessary for addressing the issue of workability and also improving the engineering properties of geopolymeric system for broad application spectrum.

  • Patent number: 9890081
    Abstract: Brine sludge is an industrial waste generated in chloral alkali industry. The generated brine sludge waste is dumped into landfills and contains barium sulphate, calcium carbonate, magnesium hydroxide, sodium chloride, clay, and toxic elements like chromium, zinc, copper, and vanadium, therefore posing an environmental threat. Consequently, there is an urgent need to convert toxic brine sludge waste into its non-toxic form. The present invention thus aims to achieve total utilization of this brine sludge for making functionalized brine sludge material useful for a broad application spectrum.
