PRODUCT DESCRIPTIONSECAR® 71 is a versatile hydraulic binder with an alumina content of approximately 70%, which is designed to be used at temperatures in excess of 1400°C. SECAR® 71, a pure cement manufactured by the sintering process, contains only calcium aluminates.
The high calcium aluminate content provides characteristics ideally suited for refractory applications where rapid hardening combined with excellent mechanical resistance and high temperature performance are required. Using SECAR® 71 as a refractory cement normally finds it as the primary binder in mortars and concretes exposed to refractory temperatures.
SECAR® 71 is preferred by many for high duty refractory concretes due to a very low iron oxide content of approximately 0.1%. SECAR® 71 is the reference product for high technology deflocculated castable systems such as LCC, ULCC, shotcrete and pumpable refractories.
Its controlled mineralogy gives the formulator great flexibility in castable design and also gives good compatibility with micro silica.
Calcium aluminate cements do not release Calcium Hydroxide as a hydration product when used as the sole hydraulic compound in a formulation.
This imparts good refractoriness and chemical resistance.
As a binder, SECAR® 71 reacts with most organic and mineral additives to achieve exceptional flow with high early compressive strength. SECAR® 71 is produced and controlled with in a quality management system that is certified according to ISO 9001.
SECAR® 71 does not contain any additives.
