Concrete Structures



Research has proved that the use of stainless steel has definite benefits but that it must be used intelligently and with careful planning and assessment of economic advantage for the future. The interest in the material is apparent but additional measures need to be instituted to further the knowledge of the engineer about the practical benefits stainless steel reinforcement presents. The second part of the chapter is concerned with differential scanning calorimetry (DSC). The thermal stability of ground granulated blast-furnace slag (ggbs) powder is examined. The third part of the chapter involves DSC of the thermal behaviour of hydration products in ggbs. The two-step loss of water from calcium silicate hydrates and dehydroxylation of calcium hydroxide (Ca(OH)2) contributes, respectively, to the two major peaks in the DSC curves. Peaks due to the formation of ettringite and Fe2O3 solid solution are also present. The crystallisation peaks from amorphous phases in the ggbs are significant in the DSC thermograms.
