Impact of admixtures used in underwater concrete on cement hydration process and rheological properties

Impact of admixtures used in underwater concrete on cement hydration process and rheological properties

This paper presents test results of the impact of chemical admixtures used in the underwater concrete technology, i.e. a superplasticizer (SP), an anti-wash admixture (AWA) and SiO2 nano- particles (NP) on the cement hydration process, rheological properties and the setting time. The impact of admix...
