Abstract: The present invention relates to advanced cement free composition for concrete and panels useful in construction industry and the method of preparation thereof. Particularly the present invention relates to advanced cement free composition constituting Sea sand, Fly Ash, Seawater, NaOH and Na2SiO3 (sodium meta silicate). More particularly the present invention relates to advanced cement free composition for concrete and panels with comprehensive strength of 15 to 30 MPa and flexural strength of 1.5-3.0 MPa.

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.

Abstract: The present invention provides a nano phosphatic hybrid geopolymeric corrosion resistant coating material. The tailored precursor of corrosion resistant coating material is obtained by a process involving, together dry grinding of raw materials fly ash, sodium hydroxide, rice husk, tri calcium phosphate and cetyl trimethyl ammonium bromide optionally with sodium silicate, in solid powder form. The developed coating material obtained by adding water to tailored precursor contains nano sized phosphatic compounds of Cancrisilite (sodium aluminum carbonate silicate hydrate), quartz, mullite, heamatite, sodium aluminum silicate, Herschelite (sodium aluminum silicate hydrate), Sucrose, ? D-Glucose, Native cellulose, and phenol, responsible for providing improved corrosion resistant properties and adhesion to the mild steel substrates. The geo-polymeric coating material is used as an anti-corrosive, heat resistant coating material on various materials e.g. mild steel substrates.
