Use fast setting concrete, so one doies not have to cover it for a longer time.
About
Instead waiting long time until the newly laid concrete is set, use fast setting setting concrete (ready to use 1-2 hrs.) so no need to cover it. https://www.youtube.com/watch?v=CLkXxYQzri8 Here an example for the repair of a runway in large scale: https://www.youtube.com/watch?v=TYudM6sbilk In case of rain you can cover the concrete with plans.
Key Benefits
With changes in the construction process using fast concrete cement, no need to cover the laid concrete for a longer time and therefore no trip hazard. In addition to safety benefits, the solution should save also costs (barriers need to be used only for a few hours instead of weeks, no cover board required, one construction team can the whole process in a few hours).
Applications
small construction projects using concrete
