MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202623043407 A) filed by Saaz Research And Development, Pune, Maharashtra, on April 5, for 'a self-curing cementitious composite material and method thereof.'
Inventor(s) include Inamdar, Yusuf A. S.; and Inamdar, Abbas, Yusuf.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "A method of preparation of a cementitious composite material, wherein said method comprises collecting used silica sand from a foundry, washing the collected silica sand with water to remove impurities, identifying chemical properties of the washed silica sand, adding calcium oxide, alumina and magnesia depending upon the identified chemical properties to form a mixture having calcium oxide 38-42 wt%, silica 33-37 wt%, alumina 11-15 wt% and magnesia 6-10 wt%, and grinding the mixture to obtain a supplementary cementitious binder. The binder is mixed with recycled construction and demolition (C&D) waste aggregates to form a composite mixture. Carbon dioxide is introduced into the composite mixture during mixing. Carbon dioxide reacts in-situ with calcium oxide and magnesia present in the binder to form carbonate phases. The composite mixture hardens under ambient conditions without external water curing to obtain the cementitious composite material. The resulting material exhibits self-curing characteristics and enables permanent sequestration of carbon dioxide."
