High alumina cement

Whoever is given priority to with calcium aluminate, alumina content is about 50% of the clinker, grinding the water rigid gelled material, known as the high alumina cement. Also known as alumina cement, high alumina cement refractory cement, aluminate cement, collectively known as aluminate cement, bauxite and limestone as raw material, after the calcination of calcium aluminate as main ingredients, alumina content is about 50% of the clinker, again into the water rigid gelled material. High alumina cement is often yellow or brown, and gray. With a rapid hardening, early strength, corrosion resistance, resistance to high temperature of the water rigid gelled material; It is a kind of high-quality building materials, is also a kind of loose refractory for gelling property, in metallurgy, building materials, oil chemical, electric power, food and other industries has been widely used.

Characteristics of high alumina cement

High alumina cement with early strength increase rate is higher, the hydration heat is larger, sulfate attack resistance is strong, and good high temperature resistance and other properties.

Fineness: more than mm square hole sieve sieve should not exceed 10%.

Setting time: setting no earlier than 40 min, the final set not later than 10 h.

Ingredients: SiO2 10% or less, Fe2O3 3% or less.

Volume stability: water slurry uniformity of volume change in the process of condensation sclerosis called the volume stability of cement. Such as volume change uneven or volume stability, prone to warping and cracking, reduce the engineering quality and even an accident.

Sulfate erosion resistance is strong, the hydration process instead of free calcium hydroxide precipitation generated aluminum hydroxide gels, form a protective film in the surface of particles, in the late crystal transformation in the process of the erosion resistance decreases.

: good resistance to high temperature alumina cement can be used as heat resistant concrete cementation material, configured to heat resistant concrete.

High alumina cement main purposes

Also known as aluminate cement, high alumina cement refractory cement, the equivalent of 625 # cement, because of its excellent fast setting, high strength, high temperature resistance characteristic, a day strength can reach 80%, up to 1450 degrees refractoriness, refractory concrete strength can reach 55 mpa, is the excellent high temperature industrial kiln project one of binder materials

1, the preparation of monolithic refractories.

2, make plaster alumina expansive cement, self-stressing cement cement and other special purposes.

3, scrambling, repair, and resistance to sulfate erosion and winter construction engineering and other special needs.
