A 5 ft (1.5 m) thick foundation mat slab has been prepared for concrete placement. Reinforcing steel was installed over a 3 in. (76 mm) thick mud (or working) slab with an area of approximately 25,000 ft2 (2320 m2) finished flat (that is, no slopes or contours). There are puddles of standing rainwater deposited yesterday on top of the mud slab in random locations that range in depth up to 1/2 in. (13 mm). Are there any ACI requirements for placing concrete in such conditions?
