## How many 20kg bags of concrete are in a cubic meter?

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..

## How many 50kg bags of cement are in a cubic meter?

I believe the standard density of 1 cement bag is equal to 1440 kg/m3. Density = mass/volume (ρ=m/V) So, V=m/ρ 50 kg ÷ 1440 kg/m3 = 0.0347 m3 = 1.23 CFT.

## How much concrete does it take to fill a hole?

If you’re not sure what size hole to dig, a rule of thumb is to use a hole diameter 3 times the post diameter and 1⁄3 as deep as the post height. See below for more information. Average is $115 per yd3, although your price will vary based on the type of concrete, vendor, and location.

## How many bags of concrete do I need for a 4×4 slab?

Enter the size of the slab you want to build in square feet. The calculator will indicate the number of 60 or 80 pound bags of QUIKRETE® Concrete Mix you need to build a 4″ or a 6″ slab. (All yields are approximate and do not include allowance for uneven subgrade, waste, etc.)

## How many bags of cement do I need for 1 cubic meter?

In general for M25 Grade concrete, which is extensively used for RCC work, cement content of one cubic meter concrete ranges from 300 kg to 350 kg. Each bag of cement weighs 50 kg and so 6 to 7 bags is required for M25 Grade concrete.

## Is 2 feet deep enough for fence posts?

The minimum depth that you should dig your fence post holes for panel sections is 2 feet. A general formula is to dig the holes one-third to one-half of the post’s aboveground height. The deeper you dig the holes, the more stability your fence has, but you must also purchase longer posts.

## How big of a hole do I need for a 4×4 post?

about 12 inches wideDig post hole so diameter of the hole is 3 times the width of the post (i.e., the hole for a 4” wood post should be about 12 inches wide). The depth of the hole should be 1/3-1/2 the post height above ground (i.e., a 6-foot tall fence would require a hole depth of at least 2 feet).

## How many 20 kg bags of premixed concrete do you need?

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.

## How much does it cost for 2 yards of concrete?

According to the NRMCA – Ready Mixed Concrete Industry Data Survey, the average cost of concrete in 2018 was $120 per cubic yard, or $240 for the 2 cubic yards needed for a typical 10-by-10-foot patio.

## How many bags of concrete does it take to fill a 2x2x2 hole?

Each hole is 2’x2’x2′ which equals 8 cubic feet. You have 2 of these so you need 16 cubic feet of concrete. An 80 lb (36.3 kg) bag of Quikrete yields approximately 0.60 cu ft (17 L). 16 cubic feet / 0.6 cubic feet / per bag = 27 (80#) bags of concrete mix.

## How many bags of concrete do I need calculator?

For concrete, the formula for volume is as follows: length x width x thickness. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. Use the following yields per each bag size: 40 pound bag yields .011 cubic yards.

## How many bags of concrete do I need for a 3 foot post hole?

I normally use post hole diggers (6″ diameter?) 3 feet deep and ½ a bag of redi-mix per post.

## Can you put dry concrete in a post hole?

Fast-setting concrete is ideal for setting posts because there’s no mixing—you simply pour the dry concrete from the bag right into the hole, then add water.

## How many bags of concrete do I need for a 10×10 slab?

For a 10 x 10 slab, you would need 77 60-pound bags or 60 80-pound bags. If we add an extra 10%, that’s an extra 8 60-pound bags or 6 80-pound bags.

## What is a 1 2 3 mix for concrete?

Concrete is made from cement, sand, gravel and water. In making concrete strong, these ingredients should usually be mixed in a ratio of 1:2:3:0.5 to achieve maximum strength. That is 1 part cement, 2 parts sand, 3 parts gravel, and 0.5 part water.
