JMI faculty’s invention on nano cement gets patent from GoI
The Patent Office of the Government of India has granted the patent to an invention titled “High Strength Cementitious Nanocomposite Compositions and the methods of making the same” by Ibadur Rahman, Assistant Professor, Department of Civil Engineering, Jamia Millia Islamia.
The main objective of the invention is to bring together nanotechnology and construction technology in order to produce nano modified cement based materials so as to achieve enhanced mechanical performance, reduced weight and most efficient utilization of the material resources.
A number of compositions having nano additives were used to make high strength cementitious composites. The influence of additive components such as nano cement, silica fume, nano silica fume, fly ash and nano fly ash in cement matrix was studied with reference to normal size cement matrix. With the addition of the nano particles, a significant improvement in the properties of cementitious matrix was observed.
The modified nano composites will be useful in strategically important structures requiring high strength like Nuclear Power Plant, Airport Runways, and Bridges etc. These materials will also be beneficial in constructing high rise buildings particularly in the Government of India Projects on “Smart Cities”.
Apart from Dr. Ibadur Rahman of JMI, Prof. Mohammed Arif, Department of Civil Engineering and Prof. Ameer Azam, Department of Applied Physics, Z. H. College of Engineering and Technology, Aligarh Muslim University (AMU), Aligarh are other two patentee.
