Possibilities of Using Waste Materials in Trenchless Renovation Piping Systems
Majerová, Jana ; Drochytka, Rostislav ; Hermann, Radek ; Figala, Petr
Properties of the resin system are key properties in the CIPP trenchless pipeline repair system. Fillers affect the properties of the resin system and the cost of renovation. One of the ecologically and economically attractive options is the use of secondary raw materials. The article describes the properties of some suitable secondary raw materials and their influence on the properties of the resin system in comparison with traditional fillers The article compares three types of secondary waste materials and the reference filler. The SiO2 content, the particle size of the filler and the mechanical parameters of the proposed recipes are most important.
