Abstract: The aim of this experimental work was to study the compressive strength, the tensile strength and the modulus of elasticity of self-compacting concretes (SCC) and to compare the results obtained with those reported for traditional concrete. Several types of concrete were made, with different water/cement ratios and different types of cement. The results show that compressive strength tends to be somewhat higher in the SCCs, although when large quantities of limestone fine are used the tendency is reversed and performance deteriorates. In the case of modulus of elasticity, the values obtained were very similar for both types of concrete, although the SCCs tended to be somewhat more deformable because of their higher paste content. Finally, the results show that tensile strength is significantly higher in traditional types of concrete (the differences being around 18%), so we propose a formula specific to SCC that enables to estimate its tensile strength from its compressive strength.
