To calculate the number of 25kg bags of ballast in a cubic meter, you need to know the density of the ballast. If the density is 1.75 tons/m³, then one cubic meter would be equivalent to 1,750 kg. Therefore, you’d need 70 bags (1,750 kg ÷ 25 kg/bag).
When you are thinking about a new project making of Pathway, driveway, patio and slab, there is need of concrete mix to pour, so there is mixing of cement, ballast and water in required proportion and quantity to achieve targeted compressive strength.
Ballast or aggregate is primary ingredient of concrete added to cement that bind ballast particles altogether, water and some additive are also added to create final paste ready for pouring.
Properties of concrete based on density of and quantity of ballast material, grade of concrete, changing the amount of ballast affect the concrete strength, lightweight ballast creates low strength concrete.
Based on Imperial system, strength of concrete measured in Pounds per square inch (psi) or megapascals (MPa), low strength concrete has strength of 2000 psi or 14 MPa, while higher strength concrete used for Super structure and Bridge is about 10000 psi or 70 MPa, and generally for civil building structure you used 5000 psi (35 MPa) of concrete strength.
Typically, weight of ballast is about 1.75 tons per cubic metre or 1750 kg/m3, it is generally available in a small bag of 25kg which yields volume around 0.015 cubic metre, there is question ask How many 25kg bags of ballast in a cubic metre of concrete.
How many kg in a bulk bag? In the UK, a typical bulk bag contains 850-875kg of ballast, or 800kg of sand. A bulk bag which is also called Builder bag which is designed to transport up to 1500 kg of load.
How many 25kg bags in a tonne? In the UK, a tonne is equivalent to 1000kg which contains 40 × 25kg bags, 50 × 20kg bags, 20 × 50kg bags, or 25 × 40kg bags of building materials i.e. sand, gravel and ballast. So, there are approximately 40 25kg bags in a tonne.
How many 25kg bags of ballast in a cubic metre of concrete
Mix ratio for mixing of cement and ballast creating a concrete suitable for driveway pathway patio are 1 part cement to 5 part of ballast, taking mix ratio of cement and ballast is 1:5 (1part cement and 5 part ballast) for calculation of number of bags of ballast and cement bags in 1 m3 concrete.
Generally one cubic metre of ballast weight around 1.75 tons or 1750kg, generally weight of one bag of ballast is around 25kg, so volume of one 25kg bag of ballast 25/1750 = 0.0142 cubic metre
Generally weight of one bag of cement is around 25 kg, 1 cubic metre of portland cement weight around 1500kg or 1.5 tons, so volume of a 25kg bag of cement = 25/1500 = 0.0166 cubic meter.
Hence,
A 25kg bag of ballast yields 0.0142 m3
A 25kg bag of cement yields 0.0166 m3
We have mix ratio for ballast is 1:5 by volume, it means 5 parts of ballast to 1 part cement, so total proportion 1+ 5= 6, so part of cement is 1/6 and ballast quantity is 5/6 of total volume of 1m3 concrete.
Typically, with a standard mix ratio of 1:5, approximately 82 × 25kg bags (2.042 tonnes) of ballast required for 1m3 of concrete. With a ratio of 1:4, 79 × 25kg bags (1.96 tons) of ballast are required for 1 m3 of concrete, and with a ratio of 1:6 1 m3 of concrete requires 84 × 25kg bags (2.1 tons) of ballast.
How many 25kg bags in a ton?
On average, there are 40 small bags of 25kg of ballast in a ton. A ton of ballast weighs about 1000kg, so number of 25kg bags in a ton = 1000/25 = 40 bags, hence, there are 40 small bags of 25kg ballast in a ton.
How many 25kg bags in a bulk bag?
There are 34 small bags of 25kg of ballast in a bulk bag or jumbo or loose ton bag. A bulk or jumbo, loose tonne bag of building material such as ballast, sand or aggregate generally weighs around 850kg, which yields 0.5m3, so number of 25kg bags in a bulk bag= 850/25 = 34 bags. So, there are 34 bags of 25kg in a bulk or jumbo or loose ton bag.
How much ballast and cement do I need
● Cement quantity = 1/6 × 1m3 = 0.166m3, we know weight of cement = volume × density, so weight of cement in kg = 0.166m3 × 1500kg/m3 = 249kg, if weight of cement bag is 25kg, then number of bags of 25kg cement as 249/25 = 10 bags, therefore you need 10 bags of 25kg cement for 1m3 concrete by using standard mix of 1:5 (1 cement:5 ballast)
● Ballast quantity = 5/6 × 1m3 = 0.833m3, we know weight of ballast = volume × density, so weight of ballast in kg = 0.833m3 × 1750kg/m3 = 1458kg, if weight of cement bag is 25kg, then number of bags of 25kg cement as 1458/25 = 58 bags, if it is jumbo bag of ballast which weight around 850kg, number of bags = 1458/ 850 = 1.7 bags, therefore you need 58 bags of 25kg ballast or 1.7 jumbo bag (bulk bag) for 1m3 concrete by using standard mix of 1:5 (1 cement:5 ballast).
Ballast is coarse aggregate, mixture of small rocks, limestone, crushed gravel and fine sand particles, In this regard, “how many 25kg bags of ballast in a cubic metre”, generally, there are 58 bags of 25kg ballast or 1.7 jumbo bag (bulk bag of 850kg) in a cubic metre concrete by using standard mix of 1:5 (1 cement:5 ballast).
