Ballast is a dense mixture of sand and gravel crushed small rock stone that’s form rough coarse aggregate used in extensive range of construction application, primary it is used for heavy duty work and making concrete.

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, available in a small bag of 25kg which yields volume around 0.015 cubic metre, one may ask “how much ballast and cement do I need for 1m3 concrete” and how much ballast per m3.

**Ballast cement mix ratio**

Ballast cement mix ratio:- for mixing of ballast and cement creating a concrete suitable for driveway pathway, patio are 1 part cement to 5 part of ballast, represented as standard ballast cement mix ratio 1:5 (1part cement and 5 part ballast) for making concrete, others mix ratio 1:4 (1 part cement and 4 part ballast) and 1:6 (1 part cement and 6 part ballast) can also be used.

**Ballast cement ratio**:- Mixing **1 part cement to 6 parts ballast** creates concrete suitable for driveways, paths and patios, and increasing the ratio to 1:8 gives foundation-strength concrete. It is of course possible to add other materials to increase the strength of the concrete – these often include steel reinforcing bars.

**Concrete mix ratio using ballast**:- to create concrete mix of specific high strength, concrete mix ratio would be 1:5 (mixed using 1 part cement to 5 parts ballast) used for building slabs or concrete panels. Ratio for concrete mix using ballast is 1:6 (mixed using 1 part cement to 6 parts ballast) creates concrete suitable for driveways, paths and patios.

**How much does a cubic meter of ballast weight**

Regarding this, “how much does a cubic metre of ballast weight?”, it’s depending on wet and moist condition but generally one cubic metre of ballast weight around 1.75 tons or 1750kg.

**How many cubic metre in a bag of ballast?**

Generally weight of one bag of ballast is around 25kg and a bulk or jumbo bag of 1 loose tonne ballast weight around 875kg, so volume of one 25kg bag of ballast yields 25/ 1750 = 0.0142 cubic metre volume and a jumbo bag yields about 0.5 cubic metre (875/1750 = 0.5 cubic metre).

Regarding this, how many cubic metre in a bag of ballast?, generally a bag of ballast of 25 kg yields 0.0142 cubic meter volume and a bulk or jumbo bag yields 0.5 cubic meter.

**How many cubic metre in a bag of cement?**

One may ask, how many cubic metre in a bag of cement?, 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 there are 0.0166 cubic meter in a bag of 25 kg cement.

**Hence**,

● A 25kg bag of ballast yields 0.0142 m3 volume

● A 25kg bag of cement yields 0.0166m3 volume

● A bulk bag of ballast yields 0.5m3 volume

● A jumbo bag of ballast yields 0.5m3

● A loose tonne bag of ballast yields 0.5m3.

**How much ballast and cement do I need for 1m3 concrete**

To calculate the quantity of cement and ballast for 1m3 concrete you should do the following calculation:-

● Cement to ballast ratio:- we have standard 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

● Quantity of cement for 1m3 concrete:- 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 calculator for concrete:-quantity of ballast for 1m3 concrete is calculated as follows, ballast quantity = 5/6 × 1m3 = 0.833 m3, we know weight of ballast = volume × density, so weight of ballast in kg = 0.833m3 × 1750kg/m3 = 1458kg, if weight of ballast bag is 25kg, then number of bags of 25kg ballast as 1458/25 = 58 bags, if it is jumbo or bulk bag of 1 loose tonne 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 of 850kg) for 1m3 concrete by using standard mix of 1:5 (1 cement:5 ballast).
