Abstract
In this study, the workability (flow, setting time, heat of hydration), mechanical performance (flexural, compressive strength), and microstructure (SEM image, XRD pattern) of domestic high strength alumina cement grout (H1, H2) were examined in order to assess their applicability to marine construction. Based on data of the southern sea water temperature per the Korea Meteorological Administration, the range of 5~20 °C was selected as the curing temperature variable, and fresh water and seawater curing conditions were also considered. The results indicate that both H1 and H2 satisfy the performance requirement set by KS F 4044. However, it is noted that the compressive strength of the grout can decrease from ±5 to 18 % when cured in sea water, as compared to those cured in tap water. The change in the compressive strength, with curing conditions, is presumably attributed to CaO/Al2O3 and Al2O3/SO3 ratios.
