High Alumina Silicate Refractory Cement with Ca50 for Castable

Aluminate cement also named high alumina cement, caclium aluminate cement, refractory cement .Our refractory cement divide into normal grade and high strenght grade aluminate cement.Normal grade aluminate cement is widely used in refractory castable, gun-mix refractory etc unshaded refractory materials,shuc as refractory castable for boiler wall,beam.Normal grade aluminate cement data as follows:Grade NameNormal grade CA50Type No.X5X6X7ChemicalComponentSiO2≤8≤8≤7.5Al2O3≥50.0≥50.0≥52.0Fe2O3≤2.5≤2.5≤2.0R2O≤0.4≤0.4≤0.4Main crystal phaseCASecondary phaseCA2,C12A7,C2AS,CTResidue after 325Mesh(%)≤15Blaine  (m2/kg)≥300Initial setting time(min)≥30Final setting time(h)≤6Flexural strength (Mpa)1d5.566.53d6.577.5Compressive Strength(Mpa)1d4045503d505560      Packing of our aluminate cement:25kg/50kg/1000kg woven water proof bags, or as per customers' requestHigh strength aluminate cement is widely used as binder in special unshaped refractory materials which has demands of early and high strength,such as refractory castable for CFB cyclone tube.High strenght refractory cement data as follows:Grade NameHigh strength CA50Type No.X9NFUSEDChemicalComponentSiO2≤7.0≤7.0≤6.0Al2O3≥55.0≥55.0≥55.0Fe2O3≤2.5≤2.5≤2.5R2O≤0.4≤0.4≤0.4Main crystal phaseCASecondary phaseCA2,C2ASC12A7,C2ASC12A7,C2ASResidue after 325Mesh(%)≤15Blaine  (m2/kg)≥400≥350≥400Initial setting time(min)≥90≥30≥120Final setting time(h)≤6≤6≤8Flexural strength (Mpa)6-8h-441d86103d10711Compressive Strength(Mpa)6-8h-30301d7050753d806080        Packing of our aluminate cement:25kg/50kg/1000kg woven water proof bags, or as per customers' request  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
