| abstract |
The present invention relates to a formulation of a high-performance foamed cement material, comprising: at least one hydraulic binder, microparticles whose grain size ranges between 0.1 and 30 μm, whose proportion ranges between 15% and 50% by mass in relation to the mass of hydraulic binder, mineral particles whose grain size ranges between 1 and 500 μm, whose proportion ranges between 10% and 35% by mass in relation to the mass of hydraulic binder, the proportion of particles being lower than the proportion of microparticles, a hydrosoluble polymer thinning agent whose proportion ranges between 0.1% and 8% by mass in relation to the mass of hydraulic binder, water whose proportion is at most 40% by mass in relation to the mass of hydraulic binder, a foaming agent whose proportion ranges between 0.1% and 10% by mass in relation to the mass of hydraulic binder. |
