If these cracks become too large, they will lead to corrosion of the steel reinforcement, which not only results in an unattractive appearance, but also jeopardizes the structure’s mechanical qualities. That is why engineers often use a larger than the necessary amount of steel reinforcement within a concrete structure in order to prevent the cracks from becoming too large. This extra steel has no structural use and is an expensive solution as steel prices are high. Another way to deal with cracks is to repair them. The ultimate solution would be self-healing concrete, which is exactly what TU Delft researchers are working on. By embedding calcite-precipitating bac...

CIVIL STUDENTS SOCIETY BITS, Pilani AAC BLOCKS THE NEW RED BRICKS IN INDIA Civil engineering is one branch which will never get old because housing and infrastructure will always remain the top priority for the mankind anywhere. And so arises the necessity to keep it advancing with newer technology and easier means to sustain it. In this article I would like to introduce to the readers a building block which has now started replacing the conventional red bricks that have been in use for the time memorial. I am certain not many have heard of the ACC or AAC blocks that have come up recently in India to build malls or institutes. In my recent visit to a site in the central Delhi, where India’s largest police headquarters are being made i got to know about this alien material which will stand as high as 17 floors along with two floor basement.  Though AAC was introduced to the world in 1932 in Sweden however the Indians have got this in use in the 21st century. There are immense ...
