Abstract: The use of curing compounds on fresh concrete is well known to prevent moisture loss of the surface.
When excessive moisture loss is not prevented,plastic shrinkage cracking is likely to occur and there will be a lack of water to hydrate the cement,resulting in a concrete with lower surface strengths and lower durability.
On the occasion of CEN activities concerning curing compounds,a Belgian national working group was installed to study a new test method for curing compounds.
The existing project standard developed by TG 11 of CEN TC 104/SC3 was xamined and some minor modifications were made.
A round robin test was carried out with the collaboration of 5 Belgian test laboratories.
Eight curing compounds and water were tested.
A linear relationship was found between the relative compressive strength at 28 days and the efficiency to vaporation at 7 days in a climate room.
This relationship is explained by calculations based on the degree of hydration for which values were estimated based on the measured weight losses of the specimens.
