Low cement castable, also named as low cement castable refractory, is a kind of unshaped refractory castable. This Low cement castbales are made of superfine power, aluminate cement, anti detonant and water reducer.

Low-cement, ultra-low cement refractory castables refer to castable refractories with a calcium aluminate cement addition of less than 8%. According to the American ASTM regulations, the CaO content in low cement castables is less than 2.5%, generally between 1.0% and 2.5%. When the CaO content is less than 1.0%, it is called an ultra-low cement castable. Unlike ordinary refractory castables, some or most of the calcium aluminate cement in the matrix of low cement and ultra low cement castables is replaced by ultrafine powder with the same or similar chemical composition as the main material. At the same time, an appropriate amount of dispersant (water reducing agent) and a certain delayed coagulant are added.
Low cement castables refractory material has the merits of high density, low porosity rate, good hot strength, high refractoriness and high refractoriness under load. Besides, the low cement refractory castable has strong mechanical spalling resistance, shock resistance and corrosion resistance ability.
High density
Low porosity rate
Good high temperature strength
High refractoriness
High refractoriness under load
Strong in mechanical spalling resistance, shock resistance and corrosion resistance.
Due to the Properties of Low cement castable high alumina, it is widely used in the following thermal equipments. Such as heating furnace in metallurgical industry, boilers in power industry and building material industrial furnace.
