The goal of this project was to develop self-levelling concrete at lower cost than traditional self-levelling concrete. The concrete of this study was only 20% more expansive than usual concrete utilized for building concrete. Laboratory and on-site data proved that this objective could be reached if the mixture contained: 260kg/m3 normal portland cement,-140kg/m3 powdered limestone,-10kg/m3 chemical admixture composed of a superplasticizer and a viscosity agent. The production of this concrete was followed for one year and the main engineering properties investigated. The 28-day strength was higher than 30MPa and the water-permeability was low, 10-12m/s. 8,000m3 of such concrete were placed within one year and suggested that self-levelling concrete could be an interesting solution to improve the productivity on-site and the quality of buildings.
