ETCONP TRIVIA #5

Let’s talk about cost break down

Estimate the cost of 1 m³ C25 concrete (1:2:3 ratio)

Consider 20% profit

Given
- 1 truck of sand is 50,000 birr
- 1 truck of gravel 48,000 birr
- 1 quintal of cement is 1600 birr

Labour

- Daily laborer (DL) = 450 birr per day

- foreman = 1,200 birr per day
- carpenter = 1,000 birr per day

Machine

- mixer = 1,600 birr per day

1. Calculate the cost of 1m³ concrete

2. Calculate UF (utilization factor) ?

3. How many liters of water required

#Answers

To estimate the cost of 1 m³ of C25 concrete (1:2:3 ratio), we need to consider the following:

1. Calculate the cost of 1 m³ concrete:

Concrete mix ratio (1:2:3):
- Cement: 1 part
- Sand: 2 parts
- Gravel: 3 parts

Assuming 1 m³ of concrete:
- Cement required = 1 part = 0.333 m³
- Sand required = 2 parts = 0.667 m³
- Gravel required = 3 parts = 1.000 m³

Cost calculation:
- Cement: 0.333 m³ x (1600 birr/quintal) / 0.05 m³/quintal = 10,656 birr
- Sand: 0.667 m³ x (50,000 birr/truck) / 50 m³/truck = 667 birr
- Gravel: 1.000 m³ x (48,000 birr/truck) / 50 m³/truck = 960 birr
- Labor:
- Daily laborer: 1 day x 450 birr/day = 450 birr
- Foreman: 1 day x 1,200 birr/day = 1,200 birr
- Carpenter: 1 day x 1,000 birr/day = 1,000 birr
- Machine (Mixer): 1 day x 1,600 birr/day = 1,600 birr

Total cost of 1 m³ concrete = 10,656 + 667 + 960 + 450 + 1,200 + 1,000 + 1,600 = 16,533 birr

2. Calculate the Utilization Factor (UF):
The Utilization Factor (UF) is the ratio of the actual time used for a specific activity to the total time available for that activity.

UF = Actual time used / Total time available

For this case, let's assume the total time available for the concrete work is 8 hours per day.

UF = (Actual time used) / 8 hours
UF = (1 day) / 8 hours = 0.125

3. Water requirement:
The water requirement for 1 m³ of C25 concrete (1:2:3 ratio) is typically around 180-200 liters.

Therefore, the water required for 1 m³ of C25 concrete is approximately 190 liters

As we all know the strength of concrete has many factors one of thr factor that affects the strength of concrete is W/C( water cement ratio) ... NOW my question is what happens is W/C is lesser ? What happens if W/C is higher ?
