EROSION AND ABRASION RESISTANCE OF SOIL-CEMENT AND ROLLER-COMPACTED CONCRETE

Soil-cement and roller-compacted concrete (RCC) are increasingly being used in severe conditions such as spillways, bank protection and other water resource applications, where durability against erosion and abrasion is an important design criterion. This report contains the results of a literature search of laboratory tests and field performance studies investigating erosion and abrasion resistance of soil-cement and RCC. The report is also based on the results of a survey of methods used to design soil-cement and RCC subjected to high velocity or debris-laden flow. Findings indicate that the erosion resistance of soil-cement and RCC increases with increased compressive strength, harder aggregates and a greater percentage of coarse aggregate in the mix design. Both laboratory and field studies show that the rate of erosion of soil-cement and RCC diminishes over time. Soil-cement contains little coarse aggregate, so its erosion resistance is controlled by the compressive strength of the cement paste. For high flow velocities of clean water or abrasion erosion conditions, compressive strength needs to be increased or RCC used. The criterion for mixture proportioning of RCC to withstand erosion is to specify a certain minimum compressive strength at a certain age. For the most extreme exposure conditions, improved erosion resistance can also be obtained by using the hardest available aggregate in the RCC mix.
