The present invention discloses a system and process for producing a variety of dry mix construction and ancillary construction materials (DMC) with improved structural properties. The said system and process employs a material classification unit (204) that classifies at least one of plurality of raw materials (A, B, . . . N) based on their particle size and physical properties. These classified raw materials are stored separately in material handling compartments (260) and are selected according to the construction grade requirements of the end user. The invention further involves the use of a material selection unit (210) which controls the functioning of various components of present invention. The said system and process also provides an easy means of reutilization of industrial waste products like fly ash, blast furnace slag to produce a variety of construction and ancillary construction materials.
