To determine how many bags of cement, sand, and aggregate you need, you'll first need to know the specific mix ratio for your project (e.g., for concrete, a common mix is 1:2:3, which means 1 part cement, 2 parts sand, and 3 parts aggregate). Then, calculate the total volume of concrete needed and convert that into the respective volumes of each material based on the mix ratio. Finally, divide the volume of each material by the volume contained in a standard bag (usually 94 pounds for cement) and the bulk density for sand and aggregate to get the number of bags required.
RCC that is reinforced cement concrete which is composed of cement(mainly),sand(fine aggregate),metal(coarse aggregate)and water.Which is further more supported by iron which makes it RCC from ordinary cement concrete.
Fine aggregates are the aggregates whose size is less than 4.75 mm.Example: Sand is used as fine aggregate in the preparation of concrete and cement mortar.
The binder in concrete is usually cement. Cement causes the aggregate and sand to bind together mechanically and harden to make a solid surface.
Choose the grade of concrete & assume minimum water/cement ratio.Conduct some initial tests on the materials like cement, sand & metal(coarse aggregate).Tests like UNIT WEGHT, SPECIFIC GRAVITY,SIEVE ANALYSIS,SLUMP CONE TEST & COMPACTION FACTOR TEST. According to the obtained results do the mix design from IS CODE of IS800-10262 check for water cement ratio & calculate the quantity of cement, sand & coarse aggregate.
For M7.5 concrete, the common mix ratio is 1:4:8. This means:1 part cement 4 parts fine aggregates (sand)8 parts coarse aggregates. These ratio is by volume.
Aggregate, Ordinary Portland Cement, sand, water
To find out how many 94-pound bags of Portland cement are needed for a yard of sand, you typically use a 1:2:3 mix ratio (cement, sand, gravel) for concrete. Since a yard of sand weighs about 1,600 pounds, you'll need approximately 533 pounds of cement for that mix. Given that each bag of Portland cement weighs 94 pounds, you would need about 6 bags (533 ÷ 94 ≈ 5.67). Therefore, you would need 6 bags of Portland cement for a yard of sand.

Concrete is what you make a sidewalk from. To make concrete, you mix Portland cement, sand, gravel (aggregate) and water. The cement holds the aggregate together.
The number of bags of cement needed per ton of sand depends on the specific mix ratio being used for concrete. A common mix ratio is 1 part cement to 2 parts sand to 4 parts gravel, which translates to about 0.5 tons of cement for every ton of sand. Therefore, if using 94-pound bags of cement, approximately 10 bags would be needed per ton of sand. However, it's essential to adjust the ratio based on the desired strength and application of the concrete.
Cement comes in bags that weigh 94 lbs. The volume of the bag is approximately 1 cubic foot. If you want to mix concrete which is a mixture of a coarse aggregate (gravel) and a fine aggregate (sand) and something to bond the two aggregates together (cement) then firstly you need to know the strength concrete that you require. For 1 cubic yard of 3000psi (pounds per square inch) strength you will need about 6 bags cement 12 cubic feet of sand and 24 cubic feet of gravel. Rule of thumb is the ratio should be 1:2:4 (cement:sand:gravel)
Actually, nothing is heated to create cement. Cement is a mechanically bonded combination of cement, sand, water, and gravel (aggregate).
From the largest manufacturer of backaged Portland Cement, bags come in 92.5 lb bags. To be clear, cement is mixed with sand and often aggregate (pea-gravel up to much larger rocks or other things such as broken out concrete chunks) to make concrete. Portland Cement by itself has no structural integrity when mixed with water. It must be mixed with sand at a minimum to make a hard, useful product (concrete). Concrete comes in bags weighing 50, 60, and 80 pounds here in the US.From the largest manufacturer of backaged Portland Cement, bags come in 92.5 lb bags.

If a 20kg bag of cement=0.1m3 with 100 lots o 0.01 to 1m3 then you will need 12.5 bags per m3. So you need approx 11.5m3 of sand and 144 bags of cement (144 x 0.01 = 1.44m3) to give you a total of 12.94m3
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
