Xtralite is a light weight Aerated Autoclaved Concrete Block. It is suitable for multistoried structures as it is lighter than standard size bricks and blocks, The use of UltraTech XtraLite in construction reduces the dead load significantly and also ensures less usage of Steel and concrete. This product requires lesser number of joints, which results in saving joining materials, time and labor, UltraTech XtraLite is manufactured through a reaction of aluminum on a proportionate blend of time, cement and fly ash. During this process, the hydrogen gas that escapes creates millions of tiny air cells, rendring UltraTech Xtrlite with a strong cellular structure. This is further strengthened by high pressure steam curing in autoclaves. The product thus formed is not only light weight but also has higher compressive strength.
