For plain cement concrete, the aggregate used is of size 20 mm. For RCC structures, it is 40mm and for roads, it is 80mm
One cubic metre of concrete weighs 2.5 Tonnes. Typically, 1m3 of concrete is made up of 350Kg of cement, 700Kg of sand, 1,200Kg of chippings and 150 Litres of water.

5,000,000 barrels of cement were used to make the 4,300,000 cubic yards of concrete required.

4.50/bag cement, required for 1 cubic metre of concrete ( M10).
A typical mixture of concrete will be 10 to 15% cement, 60 to 75% aggregate, and 15 to 20% water.

To produce 1 cubic meter of concrete, the typical mix design requires approximately 1.5 to 2 cubic meters of sand and aggregate combined, depending on the specific mix ratio. A common mix ratio is 1 part cement, 2 parts sand, and 3 parts aggregate, which translates to about 0.5 cubic meters of sand and 0.75 cubic meters of aggregate. However, the exact quantities can vary based on the desired strength and application of the concrete. Always refer to a specific mix design for precise measurements.
To determine how many 50 kg cement bags are required for 1 cubic meter of Grade 30 concrete, we need to break down the mix ratio and calculate the cement content based on that. Grade 30 Concrete Mix Ratio Grade 30 concrete typically has a mix ratio of 1:2:3 (Cement: Sand: Aggregate) by volume. This means: 1 part cement 2 parts sand 3 parts aggregate (gravel) However, the actual proportion of cement required can vary slightly depending on the specific mix design used by a contractor or engineer. For standard Grade 30 concrete, the cement content is typically around 350 to 400 kg per cubic meter. Since each cement bag weighs 50 kg, the number of bags required for 1 cubic meter of Grade 30 concrete would be: Number of bags = 350 kg / 50 kg = 7 bags

The cement density is used in the calculation of the total aggregate content and of the concrete density.Normal concrete has a density around 2400 kg/cubic meter or 4048 lb/cubic yard. There are many different kinds of concrete, many of which are much lighter. Cement is the liquid (or paste like) form, and tends to be much heavier than when it has cured into concrete. "Cement" is not concrete, but can be used to make concrete by mixing with sand, stone and water. The density of cement is about 3120kg/m3.
