How are RCC mixtures for water resource applications proportioned using the soils spproach?
As roller-compacted concrete (RCC) increases in popularity, many professionals from diversified fields are designing RCC mixtures. Because RCC is a dry mixture that is compacted like controlled granular fill and because after curing RCC behaves like concrete, there are two approaches to proportioning RCC mixtures: soils approach and concrete approach. Generally, professionals with geotechnical background tend to follow the soils approach and professionals familiar with proportioning concrete mixes tend to favor the concrete approach. The soils approach is outlined in the following steps: • Selection of aggregate • Estimating a cementitious content range for trial mixes • Performing a modified Proctor test on one RCC mixture containing mid-range cementitious content and determining the maximum dry density and optimum moisture content • Molding and testing cylindrical specimens • Determining cementitious content based on test results and project requirements First, a suitable aggregate s
