R&D Knowledge Sharing Session on ‘Self Healing Mechanism on Concrete’ & ‘Use of CABKOMA rods for Earthquake Resistance’

The Department of Civil Engineering, Don Bosco College of Engineering, had its sixth session under R&D cell on April 19, 2021. The two speakers for this session were Prof. Shruti Jambhale and Prof. Nadya Baracho.
Prof. Shruti presented on ‘Self Healing Mechanism on Concrete’. The speaker explained that to overcome the problem of cracking in concrete, autonomous self-healing mechanism is introduced in the concrete which helps to repair the cracks by producing calcium carbonate crystals which block the micro cracks and pores in the concrete. The speaker also highlighted that the selection of the bacteria is done according to their survival in the alkaline environment such as B. pasteurii, Bacillus subtilis and B. sphaericus.
Prof. Nadya presented on ‘Use of CABKOMA rods for Earthquake Resistance’. CABKOMA rods were introduced as a composite material made of carbon fibers in a thermoplastic resin. The rods are used as retrofitting for existing structures to resist earthquakes by either connecting the rods from roof to ground or by using as a shear wall.
Both the sessions were well received by the audience.
