Alternatives to heat curing
In the production of precast elements, special focus is given to optimizing early strengths. High early strengths are a prerequisite for two-shift or three-shift operation with the corresponding formwork cycles and high production output. These goals are typically achieved by using cement-rich concrete formulations with low water-cement ratios and high-strength Portland cements. Heat curing is also applied in many cases. This still widespread course of action is not only the opposite of a sustainable concrete design but may, in the case of heat curing, also result in serious problems with...
