The porosity, pore distribution and morphology are important features of the concrete pore
structure which may have a significant impact on the macroscopic mechanical properties …

In the present study, the characteristic hydrates (CAH 10, C 2 AH 8, and C 3 AH 6) were
evaluated at individual curing temperatures (10° C, 25° C, and 40° C), and the influences of …

MgO-bonded castables are one of the promising non-cement bonded refractories used for
ladle lining. To make crack-free MgO bonded castables, the formation of layered double …

In this study, nano CaCO 3 was added to CAC to prepare mono-carbonate hydrate (C 4 AcH
11). The mechanical properties, pore structure, and fracture behavior at high temperatures of …

The introduction of pores to improve the toughness of alumina ceramics is considered to be
a feasible strategy by using the inhibitory effect of pores on crack propagation. However, the …

The carbonation treatment of recycled concrete aggregates (RCA) can significantly enhance
their properties and reusability. To improve carbonation efficiency, a wet cyclic carbonation …

In this work, lightweight refractories were successfully prepared by using microporous MgO-
Mg (Al, Fe) 2 O 4 aggregates and magnesia powder as raw materials. The effect of the Mg …

Lamellar hydrates of CAC were designed with the introduction of Mg-Al hydrotalcite (MAH),
and the effects on the early setting behavior, demolding strength, pore structures …

The alumina-magnesia castables is one kind of monolithic refractories for steel ladle, whose
thermo-mechanical properties vary with temperature during the lining pre-heating process …

According to the magnesia-alumina phase diagram, the alumina-rich spinel may undergo
exsolution of corundum during firing when incorporated into the castable. This research …
