Right Answer:
**Advantages of using bentonite slurry in bored cast in situ piles:**

1. **Stability:** It helps stabilize the borehole walls, preventing collapse during excavation.
2. **Reduced Water Infiltration:** Minimizes water ingress, which can affect the concrete quality.
3. **Soil Removal:** Facilitates the removal of cuttings from the borehole.
4. **Improved Concrete Quality:** Reduces the risk of contamination and enhances the bond between the concrete and soil.
5. **Control of Groundwater:** Helps manage groundwater levels during construction.

**Disadvantages of using bentonite slurry:**

1. **Cost:** Increased material and handling costs compared to other methods.
2. **Environmental Concerns:** Potential for environmental contamination if not managed properly.
3. **Slurry Management:** Requires careful management and disposal of used slurry.
4. **Time-Consuming:** Additional time may be needed for slurry preparation and maintenance.
5. **Potential for Clogging:** Risk of clog

Right Answer:
The typical ratio of steel to concrete in slabs is about 0.5% to 1%, in beams is about 1% to 2%, and in columns is about 1% to 4%, depending on the design requirements and load conditions.

Right Answer:
If selected, I will focus on effective project planning, ensure clear communication among team members, manage resources efficiently, and prioritize safety and quality to deliver projects on time and within budget.

Right Answer:
After coming back home, I will review the day's progress on my projects, plan for the next day, spend time with my family, and relax to recharge for the following day.

Right Answer:
1 bag of cement (typically 50 kg) is approximately 1.25 cubic feet (cft).

Right Answer:
Stress concentration refers to the occurrence of higher stress levels in a material at specific points, often due to geometric discontinuities such as holes, notches, or abrupt changes in shape. These areas experience stress that is significantly greater than the average stress in the surrounding material, which can lead to failure or fatigue if not properly accounted for in design.

Right Answer:
**Merits of Hollow Blocks:**
1. Lightweight, reducing transportation and handling costs.
2. Better insulation properties, improving energy efficiency.
3. Faster construction due to larger size and fewer joints.
4. Cost-effective in terms of material and labor.

**Demerits of Hollow Blocks:**
1. Lower compressive strength compared to solid bricks.
2. More susceptible to water absorption, which can affect durability.
3. Requires careful handling to avoid breakage.
4. Limited availability in some regions compared to traditional bricks.
