Further Study of Solution Effects on Concrete and Cement in Pipe

THE first study on solution effects (1) presented at the Chicago meeting of the AWWA in 1955 reporting on investigations into the removal of calcium from concrete pipe and cement linings in water supply service concluded : 1. Concrete pressure pipe is only slightly affected by even aggressive water over service periods of 25 years and longer ; and, as a result, there has been found no case of failure or even serious damage to concrete pipe attributable to the solution effect of water on the concrete. 2. When new concrete pipe is put into use carrying water, some reaction takes place that soon stops further solution of calcium and leaves the concrete
