Effect of Secondary Fillers in Polymeric Material for CIPP on Fresh Processability

Abstract

The paper focuses on developing and testing polymeric materials for the CIPP method. The CIPP (cured-in-place pipe) method is a method, that focuses on rehabilitation without excavation, especially for sewer pipes. These developed materials are then saturated in special textile sleeves, which are pulled and cured directly in the sewer. Foam waste glass, basalt filler, waste glass from solar panels, and fly ash were used as secondary fillers for the tested formulations. The secondary raw materials in these materials improve the mechanical performance of the resulting composites and, in addition, improve their environmental and economic impact. The main subject of this paper is to verify the processability of these materials and verify their application/saturation into the textile lining. In particular, the determination of kinematic viscosity, fresh density, comparison of workability, and the so-called application test. The aim is to assess the influence of the added secondary raw materials on the processability and correct application to the lining so that the results are better or comparable to the reference material or have even better properties than the mass reference. According to research, basalt filler appears to be the most suitable secondary filler.
