It depends on the Grade of Concrete.
general grades are M15, M20, M25 etc.
here are the nos. of bag required
-------------------Bag for 1 cum---------------Bag for 5 cum
M15------------------- 6.4----------------------------32
M20-------------------- 8-----------------------------40
M25--------------------12----------------------------60

To calculate the number of bags of cement required for 1 cubic meter of M15 grade concrete, first determine the mix ratio, which is typically 1:2:4 (Cement:Sand:Aggregate). For M15 concrete, approximately 1 part cement is needed for every 7.5 parts of total volume (1 + 2 + 4 = 7). Given that one bag of cement weighs 50 kg and has a volume of about 0.035 cubic meters, you would need around 7.5 bags of cement for 1 cubic meter of M15 concrete.
To calculate the cement ratio for 1 cubic meter (cumic) of concrete, you first need to determine the mix ratio (e.g., 1:2:4 for cement, sand, and aggregate). The total parts of the mix are summed, and the volume of cement is calculated based on the proportion of the mix. For example, in a 1:2:4 mix, the total parts are 1 + 2 + 4 = 7. The volume of cement needed is then (1/7) × 1 cubic meter, which equals approximately 0.143 cubic meters. Given that one bag of cement typically weighs 50 kg and occupies about 0.035 cubic meters, you would divide the volume of cement by the volume per bag to find the number of bags: 0.143 / 0.035 ≈ 4.1 bags.

To calculate the amount of cement needed, first convert the dimensions of the sidewalk into cubic yards. The sidewalk's volume is ( \frac{4}{12} ) feet thick × 3 feet wide × 40 feet long = 40 cubic feet. Since there are 27 cubic feet in a cubic yard, the volume in cubic yards is ( \frac{40}{27} \approx 1.48 ) cubic yards. At $76 per cubic yard, the total cost would be approximately ( 1.48 \times 76 \approx 112.48 ).
