Seven kinds of coals (C, 77.S89.8 wt% daf) were oxidized with air at 150ยฐC for 1, 5 and 10 h. The oxidized coals were heat-treated at various temperatures between 300 and 1500ยฐC with intervals of 50 or 100ยฐC. The pore-structure of the oxidized coals and the cokes or chars obtained from the oxidized

This paper deals with the attack of cement paste by MgSO 4 and MgCl 2 solutions. The analysis of the pore structure using mercury porosimetry reveals distinct characteristics of both types of corrosion. MgSO 4 is associated with the densification of the pore structure, whereas MgCl 2 corrosion is
