Introduction
SECAR 71 is a water-hardening bonding agent with an aluminum oxide content of approximately 70%. It is suitable for high-temperature environments, withstanding temperatures exceeding 1400°C.
SECAR 71 is a pure calcium aluminate cement produced by the calcination method and contains only calcium aluminate mineral phases. As such, it not only provides the desired hardening properties for refractory products but also offers excellent mechanical strength and high-temperature performance.
Chemical composition: The aluminum oxide (Al₂O₃) content is approximately 70%, and the calcium oxide (CaO) content is about 29%. It also contains a small amount of silicon dioxide (SiO₂) and a very low amount of iron oxide (Fe₂O₃), along with other impurities. The Fe₂O₃ content is typically no more than 0.4%.
Physical And Chemical Specifications
Advantage
SECAR 71 cement contains no admixtures, ensuring excellent adaptability and compatibility with variations in the type and quantity of additives in any castable using an anti-flocculation system. This allows greater flexibility in optimizing formulations. As a result, it is often recommended for use in low-cement, ultra-low-cement castables, self-flowing castables, and wet-sprayed products.
SECAR 71 exhibits good rheological properties and is suitable for a wide range of construction methods, particularly casting and spraying.
Its chemical composition makes SECAR 71 especially suitable for use in high-purity environments, such as those involving strong reducing atmospheres like hydrogen and carbon monoxide.
Application
Primarily used as a refractory binder, SECAR 71 is widely applied in industries such as iron and steel, non-ferrous metals, building materials (cement, glass, ceramics), petrochemicals, energy, and waste incineration. It is suitable for use in various types of industrial furnaces and kilns, as well as in the production of refractory castables, ramming mixes, plastics, spray coatings, and other monolithic refractory materials. It can be used at temperatures exceeding 1400 °C.
