Description of Calcium Aluminate Cement Calcium aluminate cement, alumina cements or high alumina cements are obtained by the reaction at high temperature of lime (from limestone) and alumina (contained in natural minerals like bauxite). The aluminate cement obtained after cooling is a hard mineral: calcium aluminate clinker. Ground into a fine powder, the clinker becomes calcium aluminate cement (CAC) which forms a paste when mixed with water. The aluminate cement has the ability to harden very quickly: it forms a rigid solid within 24 hours. Application of Calcium Aluminate Cement There are two distinct ways to use calcium aluminates: as high-performance binders and as mineral reagents in a variety of industries. As binders, calcium aluminates are used in concretes and mortars for specialized applications for their properties of resistance to corrosion, abrasion and heat combined with rapid hardening and the ease of controlling grading variations. Calcium aluminate cements are also used in combination with other fine components. Hydraulic binders with new properties are then obtained. In this way, the calcium aluminate powder acts as both a complex hydraulic binder and a mineral reagent interacting with the other components in the mix. As reagents, calcium aluminates are found in non-hydraulic systems. This is the case in metallurgical treatments (iron and steel industry, foundry) where specific grades of calcium aluminate are used for their low-temperature melting properties and for trapping molten metal impurities.
Amorphous Calcium Aluminate Details: The mineral of amorphous calcium aluminate (non-crystalline calcium aluminate) is C12A7. The alumina content is about 50%. However, the appearance of amorphous calcium aluminate is different from crystaline calcium aluminate or CA. It looks like greenish (or a little blue color mixed) semi-transparent beads. Generally, the grains are ground into fine powders. The Amorphous calcium aluminate powder and OPC (ordinary Portland cement) and CSA cement are formulated into Rapid-hardening Mortar and Self-leveling mortar etc. With good performance of rapid strength and little dry shrinkage. Application of the Amorphous Calcium Aluminate: Shotcrete Concrete accelerator Rapid setting, rapid hardening cement Concrete ground hardening Rapid-hardening Mortars and Self-leveling mortars etc. Amorphous calcium aluminate Packing: By jumbo bags. Store in shady, cool and dry place. Avoid damp and mix with other substance For more information about thermal heat insulation and high temperature plate, please feel free to contact us!

Briquettes factory, especially briquettes for Shisha... made from 100% pure coconut shell charcoal without any other raw materials mixed in. And for the specs, we adjust to demand, starting from Premium to Super premium grades... what differentiates premium and premium grades is the ash content and ash color... for premium our ash content ranges from 2.4%-2.6 %..for super premium itself the ash level is 1.9% and the max is 2.3%..and the ash color is also super white...for premium the ash color is white and a little bit of cream.
When fully annealed, melt extract stainless steel fibers are more pliable and ductile. They not only allow for more user-friendly than the stiff cut fibers, but also have better flow features. It is especially characterized by thermal shock resistance, steep thermal gradients resistance and mechanical shock resistance, minimizing damage and delaying failure caused by cracking. Thanks to their optimum aspect radio, rapid fiber separation during the mixing phase are better guaranteed. Gives its outstanding performance in thermal shock resistance, melt extract fibers are ideal for refractory concrete used in steel works and factories.
