Abstract:This article outlines an extensive number of laboratory tests on long-term deformations of Self Consolidating Concrete, SCC. For this purpose 4 SCC and 4 vibrated concrete, VC, were fabricated, in all 88 creep specimens. The water-cement ratio, w/c, of the concrete varied between 0.27 and 0.80 and strength between 14 and 171 MPa. Studies on shrinkage, strength and relative humidity, RH, were performed in parallel. The effect of late start of drying on creep was also incorporated in the studies. The results show creep and shrinkage of SCC of the same range of order as for VC at constant strength. No significant difference between the elastic modulus of SCC and that of VC was observed at constant strength. The creep coefficient , o, developed similarly in SCC as in VC .
