The history of Cement Industry of Bangladesh is not as old as other countries have a deep-rooted legacy of construction materials. The attempt to produce cement in Bangladesh dates back to 1941 when the first Cement Factory called "Chattak Cement Factory Ltd" (formerly known as Assam Bengal Cement Company Limited) was established in Sylhet, north-eastern part of
