Abstract

A slurry is often described as solid material particles that are surrounded by a water film and with additional water within the voids that decreases the shear forces between the particles. In cement and concrete research the water amount is an important parameter. There needs to be enough water to create a proper slurry, and afterwards it is consumed by the hydration of the hydraulic phases. To distinguish between a moist powder and a slurry, the point where all particles are wetted, but no remaining water is filling the pores is defined. The thickness of the water layer can be determined by different methods and is already measured for various materials. In this research it is tried to apply the method not just to a single material, but to an AAC mixture of six different materials. The obtained values are compared with the ones known from pastes and mortars.
