Only a few years ago there was very little cast-in-place self-consolidating concrete (SCC) being used in the United States; this year, according to the National Ready Mixed Concrete Association (NRMCA), 2.8 million cubic yards will be placed, and 6 million cubic yards will be placed in 2006. Although SCC mixes are more expensive, contractors are learning that it’s possible to save money on installation, and the results for architectural concrete are much better than when more standard mixes are used. But constructing formwork for walls using SCC is challenging for contractors because lateral form pressures can be much higher than with stiffer mixes.
