Abstract
In concrete influenced by tidal seawater (drainage and revetment), the use of dry mix as an alternative implementation needs to be considered. Besides the obtained ease of implementation, the quality of dry mix concrete should be examined due to the uncontrolled water-cement factor. Therefore, this study conducted tests to determine the effects of using fly ash as a substitute for cement and bottom ash as a substitute for sand in 20 MPa concrete with the dry mix method on the compressive strength of concrete cured in freshwater and seawater. The method used in this testing involved preparing concrete mixtures according to SNI 03-2843-2000 for 20 MPa concrete quality, with fly ash as a substitute for cement and bottom ash as a substitute for sand using the dry mix method. The research results showed that the use of 30% bottom ash had a negative effect on the compressive strength of concrete cured in freshwater, while in seawater, the use of 30% bottom ash had a positive effect on the compressive strength of concrete. Furthermore, concrete with 12.5% fly ash and 30% bottom ash had a negative impact on the compressive strength of concrete.
