- Synopsis
- For the purpose of developing self-compacting concrete that uses seawater as mixing water and sea sand as fine aggregate, a new admixture capable of imparting excellent flowability and adequate viscosity to concrete using seawater and sea sand was developed, and the basic properties of fresh concrete and hardened concrete using that admixture were verified, The production of self-compacting concrete with excellent flowability and adequate segregation resistance was found to be possible through the use of the new admixture, and the resulting concrete was confirmed to have basic properties equivalent or superior to those of self-compacting concrete that uses tap water and inland sand.
- Keywords:
- seawater, sea sand, self-compacting concrete, AE and high range water reducing admixture
