Mix Design Verificationโ
Check Before Pour:โ
| Item | Verify |
|---|---|
| Strength | PSI matches specification |
| Slump | Within spec range |
| Air content | If air-entrained |
| Admixtures | Approved types |
| Aggregate | Size appropriate |
| Cement type | Per specification |
Batch Tickets:โ
- Review first ticket
- Verify mix design number
- Check water content
- Note batch time
Placement Proceduresโ
General Guidelines:โ
DO:
- Place continuously without interruption
- Deposit near final position
- Vibrate systematically
- Maintain proper slump
- Protect from weather extremes
DON'T:
- Let concrete free-fall > 4 feet
- Move concrete laterally with vibrator
- Over-vibrate
- Add water in field (without approval)
- Place on frozen ground
Vibration:โ
- Insert vertically
- Penetrate into previous lift
- Remove slowly
- Overlap radius
- Don't touch rebar with vibrator
Placement Sequence:โ
- Pre-wet subgrade (hot weather)
- Verify forms and steel
- Place concrete systematically
- Vibrate/consolidate
- Strike off to grade
- Initial floating
- Final finishing
- Curing
Weather Considerationsโ
Hot Weather (over 80ยฐF):โ
| Action | Reason |
|---|---|
| Schedule early morning | Cooler temperatures |
| Shade aggregates | Reduce mix temperature |
| Cool water | Reduce mix temperature |
| Pre-wet subgrade/forms | Prevent moisture loss |
| Windbreaks | Reduce evaporation |
| Mist/fog application | Prevent plastic shrinkage |
| Immediate curing | Prevent rapid moisture loss |
Cold Weather (under 40ยฐF):โ
| Action | Reason |
|---|---|
| Heat materials | Maintain mix temperature |
| Protect substrate | Prevent freezing |
| Insulate/heat after placement | Maintain temperature |
| Extended curing | Strength development |
| Test temperature | Monitor conditions |
| No placement on frozen ground | - |
Minimum temperature for placement: 50ยฐF and rising (typically)โ
Finishingโ
Finish Types:โ
| Finish | Description | Application |
|---|---|---|
| Screed finish | Strike off only | Covered surfaces |
| Float finish | Mag/wood float | Standard floors |
| Trowel finish | Steel trowel | Smooth floors |
| Broom finish | Textured | Exterior, slip resistance |
| Exposed aggregate | Seeded/washed | Decorative |
Timing:โ
- Don't finish too early (brings water up)
- Don't wait too long (surface sets)
- Watch bleed water
- Test with foot pressure
Curingโ
Why Curing Matters:โ
- Maintains moisture for hydration
- Develops design strength
- Prevents cracking
- Improves durability
Curing Methods:โ
| Method | Application |
|---|---|
| Curing compound | Spray on after finishing |
| Water cure | Ponding, spraying, wet burlap |
| Plastic sheeting | Cover after finishing |
| Curing blankets | Cold weather |
Curing Duration:โ
- Minimum 7 days (standard)
- Check specification requirements
- Longer in cold weather
Testing Requirementsโ
Standard Testing:โ
| Test | Frequency |
|---|---|
| Slump | Each truck or per spec |
| Air content | Each truck or per spec |
| Temperature | Each truck |
| Cylinders | Per spec (typically per 100 CY) |
Cylinder Testing:โ
| Age | Purpose |
|---|---|
| 7-day | Early strength indication |
| 28-day | Design strength verification |
Testing Documentation:โ
- Lab to provide reports
- Distribute to PM, file
- Track results
- Address low breaks
Pour Documentationโ
Document During Pour:โ
- Start and end times
- Total quantity placed
- Weather conditions
- Any issues encountered
- Testing performed
- Crew information
Daily Report Entry:โ
- All of the above
- Photos
- Any deviations from plan
Common Issuesโ
| Issue | Cause | Prevention |
|---|---|---|
| Cold joints | Delayed placement | Continuous pour |
| Segregation | Improper handling | Proper placement |
| Plastic shrinkage | Rapid drying | Wind/sun protection |
| Honeycomb | Poor consolidation | Proper vibration |
| Surface defects | Finishing too early/late | Proper timing |
