New Delhi, March 12: Indian students and researchers have developed a unique type of cement mortar aimed at eliminating the threat of nuclear radiation from power plants. This innovative mortar not only provides iron-like strength to constructions but is also capable of blocking lethal nuclear radiation.
Researchers from the Civil Engineering Department at IIT Guwahati have transformed standard cement into a ‘super mortar’ by incorporating four specific micro-particles. Learning from major nuclear disasters like Chernobyl and Fukushima, the scientists focused on creating walls that prevent radiation leakage even under extreme conditions such as earthquakes or explosions.
By using these four crucial particles, the researchers have significantly enhanced the cement mixture. Boron oxide has been added to greatly increase radiation protection. The inclusion of lead oxide has made the mortar denser and stronger. Tungsten oxide has also been integrated, which enhances crack resistance and aids in blocking various types of radiation.
Additionally, bismuth oxide has proven effective as a radiation barrier. Professor Hrishikesh Sharma from IIT Guwahati stated, “Our goal is to create next-generation materials that can withstand extreme heat and radiation like a rock.” Notably, this research has been published in the prestigious journal Materials and Structures, with significant contributions from Dr. Suman Kumar of CSIR-Rudki and student Sanchit Saxena.
Scientists are now preparing to test this mortar on a large scale with concrete. In the future, it could be utilized to secure nuclear reactors, small modular reactors, and hospital X-ray and cancer therapy rooms. The team is planning to collaborate with nuclear energy agencies and large construction companies to bring this innovation to the market.
IIT has asserted that this cement mortar is capable of preventing nuclear radiation threats. The primary aim of this research is to make nuclear plants radiation-safe. Researchers found that concrete made with this advanced mortar can effectively reduce the risk of radiation leakage.
This development enhances overall safety in nuclear reactors and other radiation-sensitive facilities. It could facilitate the construction of more reliable protective walls and structures in areas where radiation risks need to be managed. As the world moves towards expanding nuclear energy to meet growing electricity demands and climate commitments, the safety and resilience of nuclear infrastructure become increasingly critical.
To address this challenge, the research team at IIT Guwahati has modified cement mortar by incorporating four types of micro-particles. Discussing the next steps of the research, Professor Sharma added, “We are now working on extending the developed cement mortar into a complete concrete mix design.”
Plans are in place to structurally test reinforced concrete elements that include the developed mortar. The team is also working on optimizing the quantity of micro-particles to achieve an ideal balance between mechanical strength, functionality, durability, and radiation shielding performance.
