DESCRIPTION

FLAREX – SG cement is a ready to use non- shrink precision grout with excellent high early and ultimate strength. It is specially designed to provide sufficient working time and also can be placed mechanically with ease. FLAREX SG has special bonding properties incorporated into it for excellent bonding with the distressed sleeper.


In railways, the rails are fixed to sleepers by fishplates, which rest on the concrete sleepers. The parts of sleeper, which is directly under the fishplates, are subjected to repeated loads when trains pass over the rails. Over a period of time the part of sleeper, which is directly under the rails, forms a depression because of the repeated load.
