A. Concrete shall comply with requirements of ASTM C-94, and as herein specified.

B. During hot weather, or under conditions contributing to rapid setting of concrete, a shorter mixing

time than specified in ASTM C-94 may be required. When air temperature is between 85oF

(30oC) and 90

oF (32

oC), reduce mixing and delivery time from 1-1/2 hours to 75 minutes, and

when air temperature is above 90oF (32

oC), reduce mixing and delivery time to 60 minutes.

C. When air temperature is below or expected to fall below 40oF within 24 hours after concrete is

placed, the aggregates, water, or both shall be heated before mixing to obtain a concrete

temperature of not less than 50oF and not more than 80

oF at point of placement. When hot

weather conditions exist that would impair placement or strength, mixing water shall be chilled or

decreases the strength of the concrete mixture will not be permitted without prior written approval by the Engineer.

SLUMP LIMITS:

A. The concrete slump at the point of placement shall be between 2-1/2" and 4". Slump shall be adjusted within this range as required to provide proper consolidation, strikeout and surface finish.

FORMS:

A. Construct forms complying with ACI 347, to sizes, shapes, lines and dimensions shown, and to obtain accurate alignment, location, grades, level and plumb work in finished structures. Use selected materials to obtain required finishes. Solidly butt joints and provide back-up at joints to prevent leakage of cement paste. Provide form material with sufficient thickness to withstand the pressure of fluid concrete without bow or unacceptable deflection.

B. Coat contact surfaces of forms with form-release compound before forms are set. Care shall be

taken to prevent form release compound from getting on concrete bonding surfaces. PART 3 -EXECUTION SURFACE PREPARATION:

A. Prior to delivery of concrete, the subgrade shall be brought to the line and grade shown on the plans, free of irregularities, bumps, or depressions. Subgrade shall be compacted with a steel



wheel roller or tamper and all soft spots repaired or replaced. PLACING REINFORCEMENT:

C. Install welded wire fabric in as long lengths as practicable. Lap adjoining pieces at least one full

mesh and lace splices with wire. Offset end laps in adjacent widths to prevent continuous laps in either direction. Welded wire reinforcement shall be supplied in flat sheets in lieu of rolls.

CONCRETE PLACEMENT:

A. Comply with ACI 304, and deposit concrete continuously and in layers of such thickness that no concrete will be placed on concrete which has hardened sufficiently to cause the formation of seams or planes of weakness. If a section cannot be placed continuously, provide construction joints as herein specified. Deposit concrete within five feet of its final location to avoid segregation. Chutes or pipes shall be used where the vertical drop or reinforcing steel may cause segregation.

B. Consolidate placed concrete by mechanical vibrating equipment supplemented by hand-spacing,

rodding or tamping. Use equipment and procedures for consolidation of concrete in accordance with ACI recommended practices. Consolidate concrete during placing operations so that concrete is thoroughly worked around reinforcement and other embedded items and into corners.

C. Bring slab surfaces to correct level with a straightedge and strikeoff. Use bull floats or darbies to

smooth surface, free of humps or depressions. Do not disturb slab surfaces prior to beginning finishing operations.

D. Maintain reinforcing in proper position during concrete placement operations.

E. Protect concrete work from physical damage or reduced strength which could be caused by frost,

freezing actions, or low temperatures, in compliance with ACI 306 and as herein specified. Concrete shall be covered and be heated as required to keep surrounding air and contact

surfaces at 40oF or above.

F. When hot weather conditions exist that would impair placement, strength, or finish, concrete shall

be placed in accordance with ACI 305 and as herein specified. Mists of cool water shall be sprayed on forms, reinforcing steel, and subgrade, to cool and dampen, immediately prior to placing concrete.

A. Protect freshly placed concrete from premature drying and excessive cold or hot temperature.

B. Start initial curing as soon as free water has disappeared from concrete surface after placing and finishing. Weather permitting; keep continuously moist for not less than 72 hours. Begin final curing procedures immediately following initial curing and before concrete has hardened. Continue final curing for at least 7 days in accordance with ACI 301 procedures. Avoid rapid drying at end of final curing period.

C. Perform curing of concrete by moist curing, by moisture-retaining cover curing, by membrane

curing, or by combinations of these.

D. Provide moisture curing by keeping concrete surface continuously wet by covering with water, or continuous water-fog spray or covering concrete surface with specified absorptive cover thoroughly saturating cover with water and keeping continuously wet. Place absorptive cover to provide coverage of concrete surfaces and edges, with 4" lap over adjacent absorptive covers.

E. Provide moisture-cover curing by covering concrete surfaces with moisture retaining cover for

curing concrete, placed in widest practicable width with sides and ends lapped at least 3" and sealed by waterproof tape or adhesive. Immediately repair any holes or tears during curing period using cover material and waterproof tape.

F. Provide membrane curing by applying membrane-forming curing compound to concrete surfaces

as soon as final finishing operations are complete (within 2 hours). Apply uniformly in continuous operation by power-spray or roller in accordance with manufacturer's directions. Recoat areas subjected to heavy rainfall within 3 hours after initial application. Maintain continuity of coating and repair damage during curing period.
