Apr 16, 2009· Bags of cement per M3. Can anyone tell me how many bags of cement are needed for 1 cubic metre of concrete at a 3:2:1 mix. If I go to CementAustralia they say 20 bags per metre. If I go to BlueCircle they say 16 bags per metre. Which one do I believe? 14th Apr 2009, 08:17 PM #2. Terrian. Diamond Member
Aug 20, 2020· Approximately 29 bags are required for 1m3 of cement.
Nov 11, 2019· 1.Cement = 6 bags = 300 kgs. 2.Fine Aggregate = 115/0.167 = 689 kg 3.Coarse Aggregate = 209/0.167 = 1252 kg. 4.Water = 300*0.55 = 165 kg.
Actually no of cement bags will vary according to what kind of, what grade of concrete you want. Accordingly W/C ratio will vary so as cement bags. Generally 1 cement bag = 34.7 litre of cement 1 m³ of wet concrete = 1.53 m³ of dry concrete
Aug 20, 2020· So, Usually, 4% of moisture content is present in cement. Dry Density of Cement = 1440kg/m3. Each bag of cement consists of = 50kg. No. of bags in 1m3 = 1440/50 = 29bags (approx) Result: Approximately 29 bags are required for 1m3 of cement.
Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate.
Jul 03, 2011· Me think the righter is a bit conservative with his calculations. first 1m3 of concrete requires 1.52m3 of dry material for mixing due to shrinkage of concrete on setting. so, for 1:2:4 mix, Cement = 1/7*1.52*1440/50 (i.e 6.25 bags per m3 of concrete) Sand = 2/7*1.52 (i.e 0.43 m3 per m3 of concrete)
How to Calculate Cost of Concrete Work for 1 m3 of volume: Let's consider the concrete mix of M 20 (1:1.5:3), where, 1 is the part of cement, 1.5 is the part of fine aggregates and 3 is the part of coarse aggregates having size of 20mm. The water-cement ratio adopted for mixing of concrete is 0.45. 1 cubic metre of concrete
Cement being a factory made product and packaged in Bags weighing 50 kg each,its DLBD more or less fall around 1400 kg/cum. Note: 1 cum = 1000 liters. For 50 kg (01 bag cement) the volume arrived is. 1400 kg cement occupies Volume of 1 cum or 1000 liter (DLBD = 1400 kg/cum) 50kgs of cement will have volume, = 50/1400 = ~ 36 liter
Where a more structural concrete is required you may need to add neat cement to the premixed bag. As a guide, an addition of 1kg to 1.5kg per 20kg bag of Concrete Mix can be used to achieve around 32 MPa concrete (under normal conditions). preparation Formwork made from 25mm thick timber is commonly used to mould the concrete.
1 cubic meter of concrete is made up of. 1,750kg ballast. 300kg cement = 12 bags 25kg. 150 litres water. or. 1,200kg chippings. 350kg cement =14 bags 25kg

Sep 03, 2019· A 1:6 mix is 2400/7 is 342 kg of cement so 14 bags. Ah you've edited since I posted. themiddleagedun, 2 Apr 2014 #3. noseall. Joined: 2 Feb 2006 Messages: 38,561 Thanks Received: 2,470 Location: Staffordshire Country: We usually reckon on two tonnes of ballast per cube. This equates to about 80 bags at 25kg's noseall, 2 Apr 2014 #4.
10 circular holes with diameter 300 mm, filled to a depth of 600 mm, have a total volume of 0.424 m³ = approx 45.8 x 20 kg bags 46 Bags Total Bag Weight 920 kg
Dec 21, 2016· ∴ No. of cement bags required in 1 cubic meter = 0.2171/0.0347 = 6.25 bags. Note: You can use the same formula for calculating cement for other nominal mixes.
But cement is sold in bags. So, we need to convert the volume of cement into bags. The volume of a 50-kilo bag of cement is 1.25 cubic feet. So, the bag of cement is, =25.40 ÷ 1.25 =20.32 bags Say, 21 bags. Calculating The Sand Quantity. The quantity of sand is, =127 ÷ 5 × 4 =101.60 cubic feet. Say, 102 cubic feet . Summary. Wet mortar ...
Dec 30, 2011· I found from Boral 1m3 of cement you need 108 20kg bags (54-40kg) premix bags or For a one 20 kg bag equals 0.01m3. This should be easier to understand. Reply.

Total weight of concrete ingredients = 50+115+209+27.5 = 401.5 say 400 kg. Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = 0.167 cum. No. of bags required for 01 cum of concrete = 1/0.167 = 5.98 bags ~ 6 bags. From above, if the concrete mix is 1:2:4, to get a cubic meter of concrete we require. 1.Cement = 6 bags ...
For jobs where a stronger rated concrete is needed, youmay consider our High Strength Concrete Mix for your concreting purposes. Yield: One 20kg bag will cover an area of 1.1m2 to a depth of approximately 10mm. Or 108 x 20kg bags equates to one cubic metre of mixed concrete. 20kg bags can be bought individually or as a pallet of 70.
Paving mix - 1:3½ cement:all-in ballast or 1:1½:2½ cement:sharp sand:gravel. Comment: If you are wondering how 1:2½:3½ equals 1:5 ("shouldn't it be 1:6" I hear someone say), the answer is that there is a lot of space between the individual pieces of gravel which will accommodate some sand, and when 2½ parts sand is mixed with 3½ parts ...
How many cement bags in m25 concrete ? hi guys, in this post we know about how many cement bags used in m25 1 cubic metre of concrete and also know about how much cement, sand and aggregate required for m25 grade of 1m3 of concrrete. we know that concrete is generally two types RCC and PCC in which RCC is reinforced cement concrete and PCC which is plain cement concrete.
Jan 05, 2006· = 0.41 m3 of concrete Now, to calculate the number of bags 0.41m3 / 0.00512m3 per bag = 81 bags or 9 bags per hole In my mind's eye, I can't see 9 x 20 kg bags plus water fitting in the size holes you describe. 5 bags per hole sounds much closer to the mark
