Abstract

In this study, grout was poured into seawater to confirm the effect of similar marine environment and underwater erosion on the mechanical performance of domestically produced high-performance grout and compared with the existing strength. As a result of the compressive strength measurement, the specimen that simultaneously performed underwater drilling and seawater curing showed slow initial strength expression in both H1 and H2, and from the 7th day, it was confirmed to be within 2% of the existing intensity. It is believed that both grout were caused by disturbance with water during underwater drilling, and the same strength was subsequently shown as the existing strength.
