How much water is required for a 50kg, 40kg, 25kg, 20kg & 94lb bag of cement | how much water required for 1 bag of cement | how much water do i need for a 94lb bag of Portland cement | how much water required per bag cement.

When you purchasing a bag of cement such as 20kg, 25kg, 40kg, 50kg which are available in metric unit in different country and in United State a bag of cement generally weighs around 94lb which yields one cubic foot for your small project like making of sidewalk, patio, curbs steps, ramp, walkway, etc, most important question comes in mind how much water do you mix with a bag of cement?

Portland cement are used mix with sand gravel water and other approved ingredient to make concrete in required proportion to achieve desire compressive strength. 1 part of Portland cement mixed to 3 -5 parts of sand with some hydrated lime and water to make workable paste of mortar with fine consistency generally used for block/bricklaying and plastering or rendering.

How much water do I need for a bag of cement?, its depending on many factors, water cement ratio which range between 0.40 to 0.6, generally water comes with amount of cement you are using in the concrete mix, so every lb or kg of cement need about minimum 0.35 lb or kg and maximum 0.60 lb or kg of water. Its also depend on type of concrete grade, weather condition and strength of concrete do you want.

It is better to look over the cement bag for how much water should add to cement bag, may be printing advice for you, and you should follow their instruction, you should not to put little or more water in concrete mix, both are harm for concrete, so you should put required and sufficient proportion of water in concrete mix to make fine consistency and workable paste.

**How much water required for 1 bag of cement?**

Water required per bag cement depend on type of concrete grade, weather condition and strength of concrete do you want. How much water do I need for a bag of cement?, its depending on many factors, water cement ratio which range between 0.40 to 0.6, generally water comes with amount of cement you are using in the concrete mix, so every lb or kg of cement need about minimum 0.35 lb or kg and maximum 0.60 lb or kg of water.

**Calculate how much water do you need for a bag of 50kg cement in following steps:-**

● assume there is a 50kg bag of cement and water cement ratio range between 0.4 to 0.6

● calculate how much water do you need for a bag of 50kg cement, its depend on water cement ratio would be minimum 0.4 to maximum 0.60, so minimum quantity of water such as 50kg × 0.4 = 20kg, and maximum quantity of water such as 50kg× 0.6 = 30kg

● calculate volume of water in litre required for one bag of cement, as density of water is about 1kg/ litre, so 20kg water = 20 litres and 30kg water = 30 litres, thus you will need 20 to 30 litres of water per 50kg bag of cement.

Regarding this,** “how much water required for 1 bag of cement?”**, one 50kg bag of cement will require 20 to 30 litres of water, while one 25kg bag will require 10 to 15 litres of water, a

20kg bag will require 8 to 12 litres of water, one 40kg bag will require 16 to 24 litres of water or a 94lb bag of Portland cement will require 4.5 to 7 gallons of water.

**How much water required for a 50kg bag of cement?**

Regarding this, “how much water do I need for a 50kg bag of cement?”, its depend on water cement ratio and type of grade of concrete, but generally you will need 20 to 30 litres of water mix with one 50kg bag of cement along with 2.5 cubic feet of sand and 3.75 cubic feet of aggregate. This quantity of water may be little change according to weather condition or temperature.

**Mathematical calculation:-**

● cement quantity in a bag = 50kg

● minimum water quantity = 50kg × 0.4 = 20kg, approximately equal as 20 litres since density of water is 1kg/ litre.

● maximum water quantity = 50kg ×0.6 = 30 litres

● thus, you will require minimum 20 litres and maximum 30 litres of water mix with per 50kg bag of cement along with 2.5 cubic feet of sand and 3.75 cubic feet of aggregate with suitable mix ratio of 1:2:3 (1 part cement to 2 parts sand and to 3 parts aggregate).

**How much water required for a 40kg bag of cement?**

Regarding this, **“how much water do I need for a 40kg bag of cement?”**, its depend on water cement ratio and type of grade of concrete, but generally you will need 16 to 24 litres of water mix with one 40kg bag of cement (1 CF) along with 2 cubic feet of sand and 3 cubic feet of aggregate. This quantity of water may be little change according to weather condition or temperature.

**Mathematical calculation:-**

● cement quantity in a bag = 40kg

● minimum water quantity = 40kg × 0.4 = 16 litres

● maximum water quantity = 40kg ×0.6 = 24 litres

● thus, you will require minimum 16 litres and maximum 24 litres of water mix with per 40kg bag of cement (1 CF) along with 2 cubic feet of sand and 3 cubic feet of aggregate with suitable mix ratio of 1:2:3 (1 part cement to 2 parts sand and to 3 parts aggregate).

**How much water required for a 25kg bag of cement?**

Regarding this, “how much water do I need for a 25kg bag of cement?”, its depend on water cement ratio and type of grade of concrete, but generally you will need 10 to 15 litres of water mix with one 25kg bag of cement (0.6 CF) along with 1.25 cubic feet of sand and 2 cubic feet of aggregate. This quantity of water may be little change according to weather condition or temperature.

**Mathematical calculation:-**

● cement quantity in a bag = 25kg

● minimum water quantity = 25kg × 0.4 = 10 litres

● maximum water quantity = 25kg ×0.6 = 15 litres

● thus, you will require minimum 10 litres and maximum 15 litres of water mix with per 25kg bag of cement (0.6 CF) along with 1.25 cubic feet of sand and 2 cubic feet of aggregate with suitable mix ratio of 1:2:3 (1 part cement to 2 parts sand and to 3 parts aggregate).

**How much water required for a 20kg bag of cement?**

Regarding this, “how much water do I need for a 20kg bag of cement?”, its depend on water cement ratio and type of grade of concrete, but generally you will need 8 to 12 litres of water mix with one 20kg bag of cement (0.5 CF) along with 1 cubic feet of sand and 1.5 cubic feet of aggregate. This quantity of water may be little change according to weather condition or temperature.

**Mathematical calculation:-**

● cement quantity in a bag = 20kg

● minimum water quantity = 20kg × 0.4 = 8 litres

● maximum water quantity = 20kg ×0.6 = 12 litres

● thus, you will require minimum 8 litres and maximum 12 litres of water mix with per 20kg bag of cement (0.5 CF) along with 1 cubic feet of sand and 1.5 cubic feet of aggregate with suitable mix ratio of 1:2:3 (1 part cement to 2 parts sand and to 3 parts aggregate).

**How much water required for a 94 bag of cement?**

Regarding this, “how much water do I need for a 94lb bag of cement?”, its depend on water cement ratio and type of grade of concrete, but generally you will need 4.5 to 7 gallons of water mix with one 94lb bag of cement (1 CF) along with 2 cubic feet of sand and 3 cubic feet of gravel. This quantity of water may be little change according to weather condition or temperature.

**Mathematical calculation:-**

● cement quantity in a bag = 94lb

● minimum water quantity = 94lb × 0.4 = 37.6lb, since water density is 8.345 lb/ gallon so gallons of water 37.6 ÷ 8.345 = 4.5 gallons

● maximum water quantity = 94lb × 0.6 = 56.4lb, so gallons of water 56.4 ÷ 8.345 = 7 gallons

● thus, you will require minimum 4.5 gallons and maximum 7 gallons of water mix with per 94lb bag of cement (1 CF) along with 2 cubic feet of sand and 3 cubic feet of gravel with suitable mix ratio of 1:2:3 (1 part cement to 2 parts sand and to 3 parts gravel).
