High Alumina low Cement Castable Introduction High alumina low cement castable in which the micro-silica powder (particle size less than 5um) with the same or similar chemical composition as the main material of the castable is used to replace part or most of the cement, and a small amount of dispersant (water reducing agent) is added.
Alumina based low cement castable (LCC) was synthesized and then treated from room temperature to 1600°C. Ultrasonic measurements were applied with the aim to obtain results of longitudinal and transversal ultrasonic velocities as well as Young's modulus of elasticity. Changes in microstructure of the samples treated at different temperatures were observed by SEM and image analyses.

aluminate, and for chemical admixtures that accelerate the aluminate hydration. Hydration phenomena governing set and strength development Portland cement has four major phases, aluminate "C 3 A", Alite "C 3 S", Belite "C 2 S" and ferrite "C 4 AF". The aluminate is the most reactive phase, and therefore has the largest impact on ...
High Alumina Cement is manufactured from limestone or chalk and bauxite (the ore from which aluminium is obtained). The two materials are crushed and fired together using pulverised coal as a fuel. The materials fuse together and the melt is transferred into steel pans. It is finally cooled, crushed and ground into a dark grey powder.
Jun 26, 2021· Commercially available high-alumina calcium aluminate cement CA-25 C (Almatis, Rotterdam, the Netherlands) was used for this study. The cement composition was measured using a X-Supreme8000 (Oxford Instruments, Aubney Woods, Abingdon, UK) X-ray fluorescence (XRF) device using a tungsten X-ray source. The result shown in Table 1. A modified ...
Low Cement High Alumina Castable was developed on the basis of clay combined refractory castable. Its main varieties are refractory castables such as low cement, ultra low cement, and no cement. It combines the advantages of most refractory castables, and has the characteristics of high density, low porosity, high strength, low wear, thermal ...

Jan 27, 2021· High alumina refractory cement has ISO Certificate. According to different content of Al2O3, it can be divided into four types: CA-50, CA-60, CA-70 and CA-80. They are of longer setting time, high temperature resistance, better stability in air, rapid strengthening and addictive-free and suitable for contacting all kinds of castables, such as ...
Refractory cement is refractory hydraulic cementitious material use high-quality bauxite and lime as raw materials, after sintering, the clinker with alumina as the main component is obtained, then grind into fine power. It has refractoriness of not less than 1580℃.
High alumina cement refers to a fast-hardening, high-strength, heat-resistant and corrosion-resistant cementitious material. All clinker based on calcium aluminate and alumina content of about 50% and ground hydraulic cementitious material are called high alumina cement. Before, the High Alumina Cement is called bauxite cement, which is a kind ...
