摘要：

A large data set of material property tests of neat seawater-mixed OPC grout is analysed and compared with existing assumptions of EN 19902. Cube tests and cylindrical compressive strength tests show higher standard deviation than normal concrete and recommendations for acceptance criteria for quality and conformity control are made. The effect of high heat of hydration was investigated but no significant effect on strength development in the time frames considered could be reported.
