Eco-friendly building material
The VLB Janakiammal College of Engineering and Technology took up a project to use bagasse ash as an eco-friendly building material. It collected bagasse from Shakthi Sugars, Appakoodal, and used it in the study. The bagasse ash was obtained by burning the bagasse at a controlled temperature of 800 C for more than an hour. The ash was made into a fine powder and mixed with Portland
cement at different replacement levels to make concrete.
In a release, M. Usha Rani, senior lecturer of the Department of Civil Engineering of the college said that the mechanical properties of concrete were tested in the laboratory and it was found that 20 per cent replacement of cement by bagasse ash increased the concrete strength by 16 per cent.
Bagasse was the residue fibre remaining when sugarcane was pressed to extract sugar. When the waste was burnt under controlled conditions, it gave ash having amorphous silica, which had pozzolanic properties.
