Depending on their volume [mass], the ambient weather,
and the degree of prestressing, the concrete elements can be stress-relieved
usually after approx. 48 hours in case of the natural curing process. The curing process is substantially shortened by means
of a heating system. The curing time is reduced to approx. 14
-18 hours.p For concrete beds, a warm water system is usually used.
weiler supplies also hollow space beds made from steel
for heating by steam or thermo oil. In addition, steel beds
filed with concrete with internal warm water heating are offered.
As a matter of fact, this design is becoming more popular in
recent times due to its low maintenance requirements, operating
safety, and ecological advantages. -
The shortest curing time, i.e. approx. 6 hours, can be obtained
by steaming the concrete elements from the top. In this case,
the elements are covered by special foils or hoods.. However,
this method is very costly particularly in terms of energy consumption.
