This study on the self-stress loss of self-stressed ferro-cement concrete pipes shows that the self-stress loss of the pipe body is a function of time, temperature, humidity and restraint condition: the higher the ambient temperature and humidity, and the longer the time of action on pipes, the more the self-stress loss; the self-stress loss is also closely related to the restraint condition, and with a suitable content of reinforcement and well-restraining mode, the self-stress loss of a pipe can be as low as below 10%, even if the pipe is stored in the atmosphere for five years.
