Aggregate 40 coarse reactive

The type denoted as Tabular alumina—comndum matrix is made from coarse supercalcined alumina aggregates and reactive calcined alumina fines to produce a direct bonded microstructure where alumina-to-alumina bonding (corundum-to-comndum) predominates. This provides an obvious increase in hot modulus of rupture (Table 12). The microstmcture of this type of brick is shown in Figure 10. In the lower field, a tabular alumina aggregate particle resides, and it is connected to the matrix through bonds with smaller corundum crystals. [Pg.101]

According to Aitcin [20] the reactive powder concrete (RPC) was invented by Richard from Bouygues company to resolve the problem of HPC, which attained strength of 150 MPa. The best aggregates have to low strength and generate the defects in these concrete. The efforts to reduce the maximum size of coarse... [Pg.669]
