The influence of the addition of concrete slurry waste on the hydration process of Portland cement

Popis výsledku v původním jazyce

The origin of concrete slurry waste (CSW) is an integral part of the concrete production. Currently it has no practical utilization, hence it is filled out as a dangerous waste due to its alkalic character. On the other hand, it can be efficiently used during the production of new concrete mixes due the content of non-reacted particles of cement and other phases, which could contribute to the hydration of Portland cement (PC). The present paper is focused on the experimental investigation of the hydration process of cement pastes incorporating various dosages of CSW applied as cement replacement. The influence on the hydration process was monitored in terms calorimetric measurement. The attained results confirmed very low contribution of CSW to the PC hydration, thus the activity of studied waste material is negligible.
