Expected Output of Cement Concrete 1:2:4 for Per Mason Per Day

Explanation:
To calculate the expected output of cement concrete 1:2:4 for per mason per day, we need to consider the following factors:

1. Mixing Ratio:
The mixing ratio of cement concrete 1:2:4 means that for every part of cement, we need 2 parts of sand and 4 parts of aggregate. This ratio is commonly used in construction projects.

2. Volume of Cement Concrete:
To calculate the volume of cement concrete, we need to consider the volume of each ingredient in the mixing ratio. Assuming 1 part of cement, 2 parts of sand, and 4 parts of aggregate, the total volume of the mixture will be 1 + 2 + 4 = 7 parts.

3. Density of Materials:
The density of cement, sand, and aggregate may vary depending on their composition and moisture content. However, for calculation purposes, we can assume the average density values as follows:
- Cement: 1440 kg/m3
- Sand: 1600 kg/m3
- Aggregate: 1600 kg/m3

4. Mason's Efficiency:
The efficiency of a mason is the amount of work they can complete in a given time, taking into account factors like skill, experience, and work conditions. The efficiency is usually expressed as a percentage.

Calculation:
To calculate the expected output of cement concrete 1:2:4 for per mason per day, we can follow these steps:

1. Determine the volume of cement concrete per mason per day:
- Assuming the mason's efficiency is 100%, the volume of cement concrete that can be produced by one mason in a day is equal to the total volume of the mixture divided by the number of parts (7).
- Volume of cement concrete per mason per day = Total volume / Number of parts = 1/7 = 0.1429 m3

2. Adjust the volume based on the mixing ratio:
- The mixing ratio of cement concrete 1:2:4 means that for every part of cement, we need 2 parts of sand and 4 parts of aggregate.
- Adjusted volume of cement concrete per mason per day = Volume of cement concrete per mason per day * (2 + 4) = 0.1429 m3 * 6 = 0.8571 m3

3. Convert the volume to the desired ratio:
- The given mixing ratio is 1:2:4, which means for every part of cement, we need 2 parts of sand and 4 parts of aggregate.
- To convert the volume to the desired ratio, we multiply the adjusted volume by the ratio factors: 1/1, 2/2, and 4/4.
- Expected output of cement concrete 1:2:4 per mason per day = Adjusted volume * (1/1) * (2/2) * (4/4) = 0.8571 m3

Answer:
Therefore, the expected output of cement concrete 1:2:4 for per mason per day is approximately 0.8571 m3.
