An environment friendly cement invented by Dr. Ibadur Rahman, Assistant
Professor, Department of Civil Engineering, Jamia Millia Islamia (JMI) along with
other researchers from AMU has been granted a patent as an intellectual
property by the Patent Office, Government of Australia.

The main objective of the invention titled ‘A Method for Preparing Modified
Cement and Evaluating Mechanical and Chemical Properties’ by Dr. Rahman and
his co-inventors from AMU, Prof. Mohammad Arif, Prof. Abdul Baqi, Dr. M Shariq,
Er. Mohammad Gamal Al-Hagri, Er. Amer Saleh Ali Hasan is to reduce carbon
emissions.

Dr. Rahman said “There is a pressing need for the construction and other
industries to go through green revolution-in other words, industries need to
adopt and introduce environment-friendly materials.”
“This invention focuses on the effect of cement replacement with micro-silica
fume, nano-silica fume and fly ash in a combination of two additives on the
mechanical properties of the concrete mixes. The combination of micro and nanosilica fumes improves the mechanical properties of concrete and eventually the
microstructure and chemical analysis of the modified concrete show
enhancement in the morphological properties of concrete owing to pore filling
with dense and compact structure further” said the inventors.
Dr. Rahman has been working in the field of nano based modified cement and
concrete composite for the last eight years during his PhD research. Dr. Rahman
has now two patents to his credit. In September, 2020, Dr. Rahman was granted
the patent titled “High Strength Cementitious Nanocomposite Compositions and
the methods of making the same” by the intellectual property at the Patent
Office, Government of India.
