Abstract
The rheological properties of ÉD‐20‐epoxy‐resin‐based compositions filled (10–50 vol.%) with quartz sand, quartz flour, or their mixture have been investigated on Reotest‐2 and RV‐8 rotational viscosimeters. The relative viscosity of the filled compositions increased with their free volume according to the exponential equation with an exponent of 2.6. The compositions began to show an anomaly of viscosity in flowing for a content of the filler of more than 40 vol.%; the yield stress appeared for 50 vol.%. The rate of spreading of the compositions on a horizontal surface decreased with increase in the composition viscosity according to the exponential equation with an exponent of 1/8, which is similar to that calculated theoretically. The experiments conducted allowed calculation of the formula of epoxy‐based, self‐leveling pouring floors.
