Purpose

The function helps users estimate the amount of gravel, cement, and sand required for Plain Cement Concrete work based on user input.

Use Cases

• Users planning to undertake concrete work at their home or construction site.
• Users looking to calculate the materials needed for a specific concrete project.

How to Use

1. Enter the values in the input fields provided.
2. Click on the "Calculate" button to get the estimated quantities of gravel, cement, and sand.

Input Values

1. Work Thickness - Thickness of the concrete work (default unit is inch).
2. Work Length - Length of the concrete work (default unit is feet).
3. Work Width - Width of the concrete work (default unit is inch).
4. Cement Sand Gravel Ratio - Ratio of cement, sand, and gravel in the mix.
5. Sand Part - Proportion of sand in the mix.
6. Gravel Part - Proportion of gravel in the mix.
7. Mortar Dry Volume Factor - Factor for dry volume of mortar.
8. Cement Bag Volume - Volume of cement bag (default unit is cubic feet per bag).
9. Skilled Labour - Amount of work skilled labor can complete in a day (default unit is cubic feet per manday).
10. Unskilled Labour - Amount of work unskilled labor can complete in a day (default unit is cubic feet per manday).

Output Values

1. Cement - Estimated quantity of cement in bags.
2. Sand - Estimated quantity of sand in cubic feet.
3. Gravel - Estimated quantity of gravel in cubic feet.
4. CC Work Volume - Total volume of the concrete work in cubic feet.
5. Skilled Labour - Number of skilled labor days required.
6. Unskilled Labour - Number of unskilled labor days required.

Any other Instruction

• Make sure to input accurate values for the best estimate.
• Contact a professional if you are unsure about any of the input values.

Calculation Steps

1. Calculate work volume based on length, width, and thickness.
2. Determine mortar dry volume using the factor provided.
3. Calculate total cement, sand, and gravel volumes based on the ratios and parts.
4. Estimate the number of skilled and unskilled labor days needed.
