We ensure consistent quality control at every stage of production. Our plant is well supported

We ensure consistent quality control at every stage of production. Our plant is well supported by a powerful in-house modern laboratory with the latest state-of-the-art equipment for quality control and continuous improvement in the products. In addition to the well equipped and furnished chemical and physical laboratory, we have highly qualified foreign trained chemists and technicians with long experience in the field of cement who are absolutely dedicated to their work.

Raw materials are tested in this lab before they are imported and sample of cement are also tested each

Raw materials are tested in this lab before they are imported and sample of cement are also tested each and every hour during production. For quality assurance cement is tested on various parameters. For this, the chemists of M.I. Cement Factory Ltd. conduct the compressive strength test making concrete/mortal cubes of different test age-3 days, 7 days and 28 days, as per ASTM C-150, and 2 days & 28 days as per EN (European Standard) at its laboratory. Therefore we can deliver the highest quality cement to our customers.
