- Abstract
- The work presents the results of granulated blastfurnace slag activation with recycling water from ready-mixed concrete production. It was shown that this water has high pH level and used as mixing water is a good activator for slag. The compressive strength of mortars was increasing with the content of solid phase in this water, and in examined samples ranged from 1% to 10%. The drying shrinkage of mortars were close to the reference mortar from Portland cement until 3% of solid phase content in recycled water. However, if solid phase content was higher, namely 5%, 7% and 10% the shrinkage was much higher. Taking this mortar behavior into consideration, according the authors only recycled water containing up to 3% of solid phase can be used as slag activator.
