Concrete should not be placed any faster than it can be spread, struck off, consolidated, and bull floated or derbies. Spreading concrete over too large an area can allow too much bleed water to accumulate before bull floating. Screening must be completed before too much bleed water accumulates. The concrete can be finished by strike off or screening to bring the top surface of the slab to proper grade, and bull floating to level the high and low spots and submerge large aggregates. Other finishing techniques can be applied if they are required such as booming for slip resistance, edging  for compaction, jointing for control joints, floating for leveling, and adding patterns and textures for aesthetics. Newly placed concrete should be cured and protected from rapid drying, extreme temperature changes, and damage from traffic. In winter, concrete can be heated, covered, insulated and enclosed. In summer, concrete can be cured by covering it with wet burlap to protect it from drying out too quickly.
