Secar® 51

Secar® 51 is a favorite of the worldwide refractory industry for formulating castables servicing medium duty applications.  The construction chemicals industry has also found good use for this cement due to its strong reactivity and color compatibility with Portland cement.  It has also become the standard color for refractory panels in pre-fabricated, zero-clearance fireplaces in the U.S.

Secar® 51 is one of six calcium aluminate cements available in North America.  Very light gray in color, it is lighter than either Ciment Fondu® or Secar® 41.  The clinker for this cement is prepared in a separate production facility using a reverberatory furnace in which the raw materials are melted to form the clinker.  The fused, very dense clinker is environmentally stable and can be shipped around the world in bulk without concern for degradation.  One site for grinding this clinker into cement is here in Chesapeake, VA where we grind Secar® 51 to 4,000cm 2/g Blaine surface area.

Secar® 51 is a hydraulic binder with an alumina content of approximately 52%.  Composed mainly of calcium aluminate phases, Secar® 51 is ideally suited for refractory, construction chemistry or fireplace applications.  The primary mineralogical phase is calcium aluminate (CaAl2O4), which imparts excellent mechanical strength to mortars and concretes.  With less than 2% iron oxide, Secar ® 51 is well adapted to refractory applications including those of reducing environments. Secar® 51 is also recommended for use in products requiring rapid hardening, resistance to abrasion, mechanical shock, intermediate temperature exposure or where other high performance properties are required of cement.

Secar® 51 is available packaged in 94-lb. bags, 3,000-lb. SuperSacks, p-d (pressure differential) bulk trucks and p-d bulk rail cars.
