jailcd2020062: Basie Study on Centrifugal Forming Tube Made of Geopolymer

Abstract

The application of geopolymer sewage pipes, which have excellent acid resistance and environmental load reduction, against cement concrete sewage pipes degraded by sulfuric acid was studied. In this study, the effects of the centrifugal force, curing method, and external environment on various properties of the centrifugal forming tube were investigated after understanding the material properties of the geopolymer. The internal surface smoothness, cracks, external pressure strength, internal pressure resistance, and water absorption were examined. It was confirmed that the centrifugal force during forming affects the internal surface smoothness and cracks. Moreover, a high-performance centrifugal forming tube can be produced by the combined production method of steam and underwater curing.
