embedded items, using internal vibrators, vibrating screeds, roller pipe
screeds, or other means acceptable to architect.
2. Strike off . and level concrete slab surfaces, using highway
straightedges, darbies, or bull floats bdore bleed water can collect on
surface. Do not work concrete further until finishing operations are
commenced.

when air temperatures are expected to drop below 40 degrees F either
during concrete placement operations or before concrete has cured.
1 . Do not use frozen or ice-laden materials.
2. Do not place concrete on frozen substrates.

when ambient temperature before, during, or after concrete placement is
expected to exceed 90 degrees F or when combinations of high air
temperature, low relative humidity, and wind speed are such that the rate
of evaporation from freshly poured concrete would otherwise exceed 0.2
pounds per square foot per hour.

conditions.
2. Provide mixing water at lowest feasible temperature, and provide
adequate protection of poured concrete to reduce rate of evaporation.
3. Use fog nozzle to cool form work and reinforcing steel immediately prior
to placing concrete.
FINISHING SLABS
A. Finishing Operations -General:
1 . Do not directly apply water to slab surface or dust with cement.
2. Use hand or powered equipment only as recommended in ACI 302.1 R.
3. Screeding: Strikeoff to required grade and within surface tolerances
indicated. Verify conformance to surface tolerances. Correct
deficiencies while concrete is still plastic.
4. Bull Floating: Immediately following screeding, bull float or darby
before bleed water appears to eliminate ridges, fill in voids, and embed
coarse aggregate. Recheck and correct surface tolerances.
5. Do not perform subsequent finishing until excess moisture or bleed
water has disappeared and concrete will support either foot pressure
with less than 1 /4-inch indentation or weight of power floats without
damaging flatness.
