INDIA:

Jamia Millia Islamia (JMI) faculty have invented an environment-friendly cement. The cement was invented by Dr Ibadur Rahman, Assistant Professor, Department of Civil Engineering, Jamia Milia Islami, including other researchers from AMU. The Patent Office, Government of Australia has granted a patent to this cement as an intellectual property.

The invention is entitled ‘A Method for Preparing Modified Cement and Evaluating Mechanical and Chemical Properties,’ it’s main objective is to reduce carbon emissions.

Professor Mohammad Arif, Professor Abdul Baqi, Er Mohammad Gamal Al-Hagri, Er Amer Saleh Ali Hasan and Dr M Shariq are the co-inventors from Aligarh Muslim University (AMU).

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.”

An official statement said this invention emphasis on the cement replacement effects with micro-silica fume, nano-silica fume and fly ash in a combination of two supplements on the mechanical properties of the concrete mixes.

The inventors said that the mixture of micro and nano-silica fumes, improves the mechanical properties of concrete and ultimately the microstructure and chemical analysis of the modified concrete show amplification in the morphological properties of concrete yielding to pore filling with further dense and compact formation.

Dr. Rahman has been working for the last eight years in the field of nano-based modified cement and concrete composite during his PhD research. A JMI statement said Dr. Rahman now has two patents to his merit.

Last year September, the intellectual property at the Patent Office, Government of India bestowed Dr. Rahman, the patent titled “High Strength Cementitious Nanocomposite Compositions and the methods of making the same.”
