Castables are concretes with refractory aggregate and a high-temperature resistant (high Al2O3) hydraulic binder. Castables may be "heavy" or "lightweight insulating" and are classed Ø standard (>2.5 CaO) Ø low cement (1.0-2.5 CaO) Ø ultra-low cement ( 1.0 CaO) They are mixed with water moulded or gunned in place and allowed to cure

ii. Castables refractory materials contain binder such as aluminate cement which imparts hydraulic setting properties when mixed with water. These materials are installed by casting and are also known as refractory concretes. iii. Mortars are finely ground refractory materials which become plastic when mixed with water.

Production also began in Belgium France and Germany about the same time and export of these products from Europe to North America began about 1865. The first recorded shipment of portland cement to the United States was in 1868. The first portland cement manufactured in the United States was produced at a plant in Coplay Pennsylvania in 1871.

Dictionary of Ceramics Aluminium Oxide Refractory

General term for those types of refractory material that contain a high proportion of silica e.g. silica refractories (> 92 SiO2) and siliceous refractories (78-93 SiO2). The name derives from the fact that silica behaves chemically as an acid and at high temperatures reacts with bases such as lime or alkalis.

What Are RefractoriesThe Refractories Institute (TRI)

Refractories are ceramic materials designed to withstand the very high temperatures (in excess of 1 000°F 538°C ) encountered in modern manufacturing. More heat-resistant than metals they are used to line the hot surfaces found inside many industrial processes. In addition to being resistant to thermal stress and other physical phenomena

The resistance of concrete to chloride is good however it can be increased by using a low water-cement ratio (0.40) at least seven days of moist curing and supplementary cementitious materials such as silica fume to reduce permeability. Increasing the concrete cover over the steel also helps slow down the migration of chlorides.
