MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202641123669 A) filed by Andhra University on October 15, 2026, for A Concrete Composition With Alkali-Resistant Glass Fibre And Colloidal Nano Silica And Method Of Preparation.
Inventors include Mohammad Fayez Saded; and Prof. K. Rajasekhar.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present disclosure proposes a concrete composition (100) incorporating alkali-resistant glass fibre (110) and colloidal nano silica (112) for nano-scale interfacial transition zone densification and macro-scale crack bridging, thereby improving flexural performance, crack resistance, load-carrying capacity, and structural serviceability of the concrete composition (100). The concrete composition (100) comprises ordinary Portland cement (102), sand (104), coarse aggregate (106), water (108), alkali-resistant glass fibres (110), and colloidal nano silica (112). The alkali-resistant glass fibres (110) correspond to 1.2% by weight of the ordinary Portland cement (102), and the colloidal nano silica (112) corresponds to 2.5% by weight of the ordinary Portland cement (102).
