What is Grade of Concrete? Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix.

High-grade zircon melts at about 2190 °C, softens between 1600 °C and 1800 °C and is volume stable up to 1750 °C. In addition to a high melting point it has very low thermal expansion and good resistance to abrasion. Zircon is used when acidic refractory is required. A cheaper type of zircon-refractory is prepared by mixing zircon with alumina.
