Avoiding Scaling and Sheet Scaling Concrete Construction ...

1996-9-1  Placing concrete on a cold surface also contributes to the problem because the concrete sets more slowly and thus bleeds longer. To avoid sheet scaling: Prohibit steel troweling of air-entrained concrete. Instead, call for a float, broom, or burlap-drag finish. Use heated or accelerated concrete when placing concrete on a cold surface.
