Die laatste regel zie ik niet in: waarom ga je net water verminderen? Je hebt toch net meer water nodig om eenzelfde verwerkbaarheid te houden bij warm weer?The following is advice on practical measures
that may be taken to minimise adverse effects
of abnormally hot weather.
Materials
Avoid use of rapid hardening (high early strength) cements.
Consider use of lower heat cements such as CEM II.
Avoid use of accelerating admixtures. Consider use of retarders to
depress the early rate of cement hydration and reduce premature
stiffening from this cause. Water-reducing admixtures may also be
useful in reducing workability loss.
Ik zie vast iets heel elementairs over het hoofd?
