Keeping in touch with global standards we introduce for the first time fibre blended cement for your construction needs. This special material has super fast setting time; unbreakable compressive strength of 63 Mpa +; prevents water seepage and rusting of steel. With the presence of polyester fibre, material rebound loss is also less resulting in cost savings.
