placing concrete. None of the water applied shall be troweled or floated into surface.

B. Cure concrete surfaces by completely covering with curing paper or by application of curing

compound.

1. Waterproof Paper: Completely cover concrete surface- Lap seams and seal with tape.

During curing period check surface frequently. Spray with water as often as necessary to

prevent drying, but not earlier than 24 hours after placing concrete.

2. Curing Compound: Apply at rate recommended by manufacturer. Apply in two

applications perpendicular to each other.

3. Curing Period: Minimum 7 days.

3.9 COLD WEATHER CONCRETING

A. Heat materials for concrete when concrete is mixed, placed or cured when the mean daily

temperature is below 40 degrees F or is expected to fall below 40 degrees F with 72 hours.

Protect concrete after placing by covering, heat or both.

B. Details of handling and protecting concrete during cold weather shall be subject to approval of

the Architect. Procedures shall comply with provisions of ACI 306R.

3.10 HOT WEATHER CONCRETING

A. Protect fresh placed concrete from direct sunshine. Sprinkle forms and reinforcement with cold

water just prior to concrete placement. Every effort shall be made to minimize delays which

will result in excessive mixing of the concrete after arrival on the job.

B. During periods of excessive hot weather, 95 degrees F and above, cool concrete ingredients

insofar as possible and use cold mixing water to maintain the temperature of concrete at

permissible levels all in accordance with the provisions of ACI 305. Concrete with a

temperature above 95 degrees F at time of placement will not be acceptable and will be

rejected.

C. Maintain temperature records throughout the period of hot weather giving air temperature,

general weather conditions (calm, clear, windy, etc.) and relative humidity. Include checks on

temperature of concrete as delivered and after placement. Correlate data with the progress of

the work so that conditions surrounding the construction of any part of the work can be

ascertained.

3.11 PROTECTION OF CONCRETE SURFACES

A. Protect concrete surfaces from traffic or damage until surfaces have hardened sufficiently. If

necessary, protect exposed surfaces with 1/2" thick plywood sheets.
