What are the steps to compute for the cement (bags), sand (cu.m.), and gravel (cu.m.) required for the platform shown in the data?
To compute for the cement (bags), sand (cu.m.), and gravel (cu.m.), we need to calculate the volume of each shape and then add them together. Then, we can use the appropriate ratios to determine the quantities of cement, sand, and gravel required.
Calculating Volume of Each Shape
To calculate the volume of each shape, we use the formula:
Volume = (Length x Width x Height) / 1,000,000
Shape G:
Length: 300 mm
Width: 500 mm
Height: 4000 mm
Volume of Shape G = (300 x 500 x 4000) / 1,000,000
Volume of Shape G = 60 cubic meters
Shape C1:
Length: 400 mm
Width: 400 mm
Height: 3200 mm
Volume of Shape C1 = 0.512 cubic meters
Shape C2:
Length: 300 mm
Width: 300 mm
Height: 3200 mm
Volume of Shape C2 = 0.288 cubic meters
Shape B1:
Length: 300 mm
Width: 400 mm
Height: 400 mm
Volume of Shape B1 = 0.048 cubic meters
Calculating Total Volume
Total Volume = 60 + 0.512 + 0.288 + 0.048
Total Volume = 60.848 cubic meters
Estimating Cement, Sand, and Gravel
Cement:
Cement (bags) = Total Volume / 0.0347
Cement (bags) ≈ 1758 bags
Sand:
Sand (cu.m) = Total Volume * (2/6)
Sand (cu.m) ≈ 20.2827 cubic meters
Gravel:
Gravel (cu.m) = Total Volume * (3/6)
Gravel (cu.m) ≈ 30.424 cubic meters
Please note that these calculations are based on assumptions of standard mix ratios and bag sizes. Actual requirements may vary depending on specific mix designs or project specifications.
