Calcium Aluminate Cements
●Product Description
■Almatis produces high purity Calcium Aluminate Cements with 70 and 80% Al2O3 content. The products are widely used throughout the refractory industry.
■The 70% alumina cements are represented by three product types, CA-14, CA-270 and CA-470 TI. In the refractory industry they find their use especially in low and ultra-low cement, low moisture castables with gunning, vibration or self-flowing placement.
■CA-14 is a well-established product line. Our process enables us to produce CA-14 cement with three distinct setting time ranges, which provide the opportunity to develop products with consistent and predictable properties.
■CA-270 is a product (2nd generation of 70% alumina cements) characterized by very low water demand, excellent flowability, and high strength development.
■CA-470 TI - temperature-independent cement - improves the setting behavior of castables at low temperatures whether or not they contain silica fume. Castables with CA-470 TI exhibit a much more robust setting and avoid the setting time variation and uncertainty that are especially apparent at low ambient temperatures. The flow of silica fume-containing mixes is improved when using CA-470 TI instead of standard 70% alumina cement.
■Almatis 70% alumina cements do not contain any organic additives in order to give full flexibility in product design without any potential chemical mismatches.
■Our 80% alumina cements are represented by CA-25 R (Regular Grade), CA-25 M (Medium Grade) and CA-25 C (Casting Grade). They are used in the refractory industry in conventional and low cement castables, which require fast setting, high early strength development, and good strength at intermediate temperatures. Our process enables us to produce CA-25 cement with three distinct setting time ranges, which provide the opportunity to develop products with consistent and predictable properties. CA-25 C has a lower water demand when compared to CA-25 M and CA-25 R.
■The Almatis cement production process is designed to achieve maximum consistency. We have the ability to precisely control the cement setting times by tight control of the cement phases. The Almatis Business System (ABS) allows us to give better service by dramatically decreasing our response time and improving production flexibility.
