Developing Underwater Concrete Properties with and without Anti-washout Admixtures [ ]

This work represents an experimental investigation concerned with the development of concrete mixtures that can be used for underwater placing. These mixes shall satisfy certain requirements regarding flowability and viscosity (cohesiveness). The adopted design of the concrete mixtures discloses these main features: dispensing anti-washout admixtures, increasing the paste volume by means of pozzolana, limestone powder and bentonite powder.
