The crystals slowly engulf the superplasticizers so that they’re now not in a position to function. Without the unfavourable cost to maintain the cement particles apart, the concrete thickens again, often after about 30 to 45 minutes. Extra superplasticizers may be added to skinny the concrete again, however as the crystals grow and begin to interlock, increasingly higher doses are needed to keep the cement particles apart.
