የአሜሪካ ኩባንያዎችን የካናዳ መንግሥት በሚያወጣቸው የግንባታ ጨረታ ውስጥ መሳተፍ እንዳይችሉ እግድ መጣል ተጀመረ።

የካናዳ ትላልቅ ከተሞች የሆኑት ኦንታሪዮ እና ቶሮንቶ የአሜሪካ ኮንትራክተሮችን ለማገድ በቀዳሚነት የሚጠቀሱ ናቸው።

ካሁን በኃላ አዲስ ነገር ካልተፈጠረ በስተቀር የአሜሪካ ኮንትራክተሮች፣ መሐንዲሶች እና አማካሪዎች በጣም የሕዝብ ብዛት ባላቸው ሁለቱ የካናዳ ግዛት ውስጥ እግድ ሊጣልባቸው በመቻሉ ከ139 ቢሊዮን ዳላር በላይ ዋጋ ያላቸው የመሠረተ ልማት ፕሮጀክቶች ጨረታ ሊያመልጣቸው ችሏል።

የአሜሪካ ፕሬዚዳንት ዶናልድ ትራም ባለፈው መጋቢት መጀመሪያ በካናዳ ላይ በጣሉት እግድ አፀፋ ሊጣል ችሏል።

በዚህም በአሜሪካ ላይ የተመሰረቱ ንግዶች ከአሁን በኃላ በአስር ቢሊዮን ዶላር ገቢ ያጣሉ እየተባለ ነው።

ባለፉት ሁለት ዓመታት የአሜሪካ ኩባንያዎች 147 ሚሊዮን ዶላር የሚያወጡ የከተማ ግዢ ኮንትራቶችን አሸንፈዋል።

በፍጥነት በማደግ ላይ ባለው ደቡባዊ ኦንታሪዮ የካናዳ ግዛት በአሁኑ ጊዜ 12.6 ቢሊዮን ዶላር የባቡር ማስፋፊያን ጨምሮ የበርካታ ቢሊዮን ዶላር ሜጋ ፕሮጀክቶች የሚካሄዱበት አካባቢ ነው።

👉Concrete Slump Test

💫Detailed Procedure and Explanation

🏷The slump test is a widely used method to measure the workability (consistency and plasticity) of fresh concrete.

⏺It evaluates how easily concrete flows and indicates its water content, which affects strength and durability.

⏺The test is performed following ASTM C143 (American Standard) or IS 1199 (Indian Standard).

🚧1. Objective

⏺To determine the consistency and workability of freshly mixed concrete by measuring its slump value (vertical settlement of the concrete cone after removal of the slump cone mold).

🚧2. Apparatus Required

⏹Slump Cone (Abrams Cone):
- A frustum-shaped metallic mold with:
- Top Diameter: 10 cm (4 inches)
- Bottom Diameter: 20 cm (8 inches)
- Height: 30 cm (12 inches)
- Made of non-corrosive metal with smooth internal surfaces.

🔰Note: We Can Modify The Height and Diameter

⏹Tamping Rod (16 mm diameter, 60 cm long, rounded at one end)

⏹Measuring Scale or Ruler (for slump measurement)

⏹Base Plate (rigid, non-absorbent, and flat)

⏹Trowel (for filling and finishing)

🚧3. Step-by-Step Procedure

❇️Step 1: Preparation

- Clean the slump cone and base plate to remove old concrete or moisture.
- Place the cone on a flat, stable, and non-absorbent surface.
- Moisten the inner surface of the cone (to prevent sticking).

❇️Step 2: Filling the Cone

1. First Layer (1/3 of Cone Height - 10 cm):
- Fill the cone with fresh concrete.
- Rod 25 times evenly across the layer to compact.

2. Second Layer (2/3 of Cone Height - 20 cm):
- Fill the next layer.
- Rod 25 times, penetrating into the first layer.

3. Final Layer (Full Cone - 30 cm):
- Overfill slightly.
- Rod 25 times until fully compacted.

❇️Step 3: Finishing

- Remove excess concrete using a trowel to level the top.
- Clean any spilled concrete around the base.

❇️Step 4: Removing the Cone

- Hold the base firmly with your feet.
- Lift the cone vertically upwards slowly (5-10 seconds) without jerking.

❇️Step 5: Measuring the Slump

- Place the cone beside the slumped concrete.
- Place a straight edge (ruler) across the cone’s top.
- Measure the vertical drop (slump) from the bottom of the straight edge to the highest point of the slumped concrete.

❇️4. Types of Slump & Interpretation

🎲Slump Type| Description | Indication |

🏷True Slump

⏺Concrete subsides uniformly
⏺Ideal workability

🏷Shear Slump

⏺One side slides down more.
⏺Poor cohesion (needs remixing).

🏷Collapse Slump

⏺Concrete collapses completely.
⏺Too wet (high water content)

🏷Zero Slump
⏺No subsidence.
⏺Very stiff
⏺mix (low workability)

⭐️Ideal Slump Range:

⏺Normal RCC work: 50–100 mm
⏺Pavements & Mass Concrete: 25–50 mm
⏺Highly Reinforced Sections: 75–125 mm

🚧5. Factors Affecting Slump

- Water Content (↑ water = ↑ slump)
- Aggregate Size & Shape (rounded aggregates increase slump)
- Mix Proportions (cement-rich mixes have higher slump)
- Admixtures (plasticizers increase slump)
- Temperature (hot weather reduces slump)

🚧6. Advantages & Limitations

📍Advantages:

✔ Simple & quick test
✔ Low-cost equipment
✔ Good for field use

📍Limitations:

❌ Not suitable for very dry or very wet mixes
❌ Does not measure all workability aspects (like pumpability)
❌ Human error possible in lifting the cone

🚧7. Conclusion

⏺The slump test is a practical way to check concrete consistency before placement. A proper slump ensures good compaction, strength, and durability.

⏺If the slump is too high/low, adjustments in water or admixtures should be made.
