Calcium Aluminate Clinker &
High Purity Fused Calcium Aluminate Cements
Calcium Aluminate Clinker (cement) is a great choice of refractory raw material for monolithic refractories, and in some cases for refractory bricks as well. Calcium aluminate is flexible for various products and has allowed refractory castable technology to grow from simple conventional gun mixes and castables to formulations and installation systems that have significantly enhanced the refractory products' longer lasting, lower cost properties.
Monolithic refractory technology has grown to include calcium aluminate cements in many products with enhanced properties and installation systems such as low cement, ultra-low cement, low moisture, high density, self-flowing, pump-able and formless (shotcrete) castables.
KT refractories offer the full range of calcium aluminate clinker / cement, allowing the refractory formulator to benefit of maximization the cost / benefit ratio. Our plant manufactures cements with alumina content (purity level) ranging from 40% to 80%. All of these cements offer a high level of the calcium aluminate (CA) phase, well known for its flow-ability and rapid strength gain.
Calcium Alumina Clinker / Cement is made from calcium, alumina, and small quantities of other raw materials, mixed in proper proportion, and fused. The composition of the main phase is C12A7, C3A, C2S. Calcium Alumina Clinker / Cement has great features such as
