Abstract: In the present paper, results of an experimental campaign concerning rheological properties of hardened self-compacting concrete are presented. Two mixes of self-compacting concrete have been employed, with different compressive strength. Stress levels have been selected to cover the range of application from cast-in-place to prestressed structures.
For each mix, compressive strength and elastic modulus evolution with time have been monitored along a period of time of about one year. Creep tests have been also performed at two different stress level, 35% and 55% of compressive strength and with two different ages at loading (7 and 28 days). Influence on delayed deformation of concrete strength, stress level and aging have been observed.
Experimental data have been finally compared with international standard provision.
