Hyderabad: The pouring of concrete totalling 20,447 cubic metres in one day in the Kaleshwaram project system is not just one for the record books in the country but also puts this complex irrigation project in the top three single day concrete users in the world.
The record for single day’s pouring of concrete lies with China, which in 2000, managed a peak concrete placing intensity of 22,000 cubic metres during the construction of the Three Gorges Dam, according to a paper presented at the 29th Conference in 2004 on ‘Our World in Concrete & Structures’ at Singapore.
When China achieved this feat, it surpassed the single day concrete placement record of 19,000 cubic metres held until then by the Zhiguli (Zhigulyovskaya) Hydroelectric Station, formerly known as Kuybyshev Hydroelectric Station on the Volga River near Zhigulyovsk and Tolyatti in Samara in Russia. The dam and hydroelectric station were constructed in the 1950s. Kaleshwaram is now next only to the Chinese effort in the world.
The Three Gorges dam is the largest such structure in the world with its reservoir capacity placed at 39.3 billion cubic meters of water. Its hydroelectric station has an installed capacity of 22,500 megawatts. The Zhiguli hydroelectric station has an installed capacity of 2,315 megawatts.
