Reasons for crack propagation and strength loss in
· castables are extremely sensitive to curing and heat-ing conditions which must be carefully controlled. These drawbacks can be reduced by reducing the cement content. For this reason low cement castables (LCC) and ultra-low cement castables (ULCC) are used instead of regular cement castables (RCC) and

The effect of α-Al2O3 nanoparticles (up to 5 wt. ) on the physical mechanical and thermal properties as well as on the microstructural evolution of a dense magnesia refractory is studied. Sintering temperatures at 1300 1500 and 1600 °C are used. The physical properties of interest were bulk density and apparent porosity which were evaluated by the Archimedes method.

Strength and self-desiccation of slag-cemented paste
· Fig. 2 shows the evolution of the UCS of the Slag-CPB specimens with different initial sulphate contents (0 5000 15 000 and 25 000 ppm) and cured at early ages (1 3 7 and 28 days). From this figure it can be clearly observed that the strength development of the Slag-CPB samples at early ages is significantly influenced by the initial sulphate concentration.

REFRACTORY. Refractories are primarily in-organic ceramic materials designed to withstand very high temperatures (>1000 °F) encountered in the manufacturing process. Refractories have higher heat resistance than metals and alloys and are resistant to thermal stress physical wear and corrosion. Hence they find wide applications in oil and gas
