الملخص الإنجليزي

For high and very high performance concretes, the measurement of autogenous shrinkage and the prediction of cracking risk are problematic.

Standardized test of shrinkage measurements is not adapted for high performance concrete.

Hydrostatic weighing technique with some modifications and corrections has been used in order to measure autogenous shrinkage from the end of mixing up to 72 hours.

In this paper, experimental work conducted on different mortars based on variable types of cements Portland cement, Slag cement, (CEMI, CEM II / B et CEM V / A according to the European standards) EN 197-1 are presented Mineralogical, mechanical, chemical and physical analyses of used cements allow us to give some correlation between shrinkage measured with our device and physicochemical composition of the used cements.
