Abstract: There are few works on self-compacting concrete durability. This justified the research program undertaken by the LMDC laboratory in collaboration with CTG. The main goal of this project is to compare the durability properties of self-compacting concrete (SCC) and vibrated concrete (VC) with similar compressive strength. Therefore, several SCC and VC mixes were prepared with exactly the same materials (the SCC mix differs only from VC in containing additional powder). Many samples of each mix were cast and used for experiments relating to mechanical behaviour (mainly delayed deformations) and physico-chemical durability.Comparison of the results shows that SCC presents equivalent shrinkage rates (total and endogenous) to those of VC, but delayed deformations under load (creep) of SCC are assumed to be greater than for VC. Secondly, transport properties of self-compacting concrete and vibrated concrete seem to turn slightly to SCC advantage
