In the year 1970 (or near that period) there was a severe flood damaging the Ghana bird santuary near Bharatpur, Rajasthan. The railway line was blown away, along with a number of bridges, under costruction in the Lakheri -Bayana doubling project. Many existing small bridges were being extended. The old ones, made in lime mortar survived, whle their extended portion, in cement mortar, were washed away by flood waters !
Before cement factories came, all civil works were executed in lime.The indigenous technology, evolved after genrations, is now forgotten. Lime is a natural reversible product. As such it is ecofriendly, whereas cement concrete is an irriversible one, causing permanent damage. What shall we do when all the sky scrapers in cities become due for destrucion ?
Now we must take up this issue, for standardising procedures for lime mortar works, to replace cement concrete, in all future civil works.
