Abrasion characteristics of a cellulose-fiber reinforced cement pipe and a steel reinforced concrete pipe.

摘要

In the usage of pipes for drainage applications, durability is a major concern. The long-term performance of pipes in such applications is essential if pipes are to be used in the infrastructure. Thus, this study investigates the abrasion characteristics of two different pipes: (1) Cellulose-Fiber Reinforced Cement (CFRC) pipe and (2) Steel Reinforced Concrete (SRC) pipe, under simulated service condition. To evaluate abrasion the changes in wall thickness of both pipes subjected to two significant parameters, aggregate/water ratio and velocity of the slurry, considered as major parameters in other researches for studying abrasion characteristics of pipes. The test set-up consisted of a main frame, sewage/trash pump, slurry tank and two different pipes. In this study, abrasion test carried out over an approximately 30 days (720 hours) and the reduction of wall thickness was calibrated every day (approximately every 24 hours).; Based on the test results, the abrasion of CFRC and SRC pipes show polynomial distribution and exponential distribution, respectively. It was shown that the abrasion of Cellulose-Fiber Reinforced Cement pipe is higher than that of Steel Reinforced Concrete pipe under the given conditions for the limited number of tests concluded.
