- Examination of the Characteristics of Coal Gasification Slag Fine Aggregate and its Effect on the Strength Characteristics of Concrete
抄録
<p>The obtained quality data of coal gasification slag fine aggregate (CGS) produced by the integrated coal gasification combined cycle (IGCC) and its characteristics are summarized. The effects of the quality characteristics of CGS on mechanical properties such as the compressive strength of concrete were investigated. From these results, it was considered that CGS is expected to have pozzolanic reactivity because it had almost amorphous and has a chemical composition close to that of coal fly ash. It was also suggested that the degree of strength development of concrete using CGS is affected by chemical components such as the ratio of the modified oxide amount to SiO2 of CGS and the degree of polymerization of amorphous phase (NBO/T). Furthermore, it was confirmed that the modulus of elasticity tends to increase gradually corresponding to the CGS mix ratio, and that the tensile strength can be shown by the correlation with the compressive strength regardless of the CGS mix ratio.</p>
