Abstract
The soil-cement slope protection on three Bureau of Reclamation projects has been damaged enough to require repair. They were the first three Bureau embankments to utilize soil-cement in place of riprap and have been in service about 18 to 20 years. The soil-cement facings on other Bureau dams are in excellent condition. The lack of bond between the soil-cement lifts in combination with severe weather and wave action appear to be the main factors contributing to the damage. Laboratory tests and field test sections indicate that cement applied between the soil-cement lifts may be a practical solution to prevent damage to the facing when severe weather and wave conditions exist. Calamus Dam, currently under construction, will have an extensive test section incorporated into the soil-cement facing where both dry cement and a cement slurry will be used between soil-cement lifts.

Twenty-Year Performance of Soil-Cement Dam Facings
The soil-cement slope protection on three Bureau of Reclamation projects has been damaged enough to require repair. They were the first three Bureau embankments to utilize soil-cement in place of riprap and have been in service about 18 to 20 years. The soil-cement facings on other Bureau dams are in excellent condition. The lack of bond between the soil-cement lifts in combination with severe weather and wave action appear to be the main factors contributing to the damage. Laboratory tests and field test sections indicate that cement applied between the soil-cement lifts may be a practical solution to prevent damage to the facing when severe weather and wave conditions exist. Calamus Dam, currently under construction, will have an extensive test section incorporated into the soil-cement facing where both dry cement and a cement slurry will be used between soil-cement lifts.
