The less water you use to mix the concrete (somewhat dry but workable) the stronger the concrete mix. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or some other kind of measuring device. By measuring the mixing ratios you will have a consistent concrete mix throughout your entire project.
Concrete is in general calculated in cubic yards - cy. Required concrete for footing can be calculated as. v = 0.0031 l w t (1) where . v = required concrete - cy (cu. yards) l = length of footing (ft) w = width of footing (ft) t = depth of footing (in) 1 cy (cubic yard) = 27 cubic feet; 1 ft = 12 in
Types Of Concrete & Their Strengths. There are plenty of different purposes people have for concrete; it can be used for foundations, flooring, walls and more. But not every concrete mix is the same, and depending on what you are aiming to achieve, you need to get a concrete mix that is fit for purpose.

Mostly small batches will use a smaller stone and will be hand mixed and large batches will be mixed using a larger stone and a concrete mixer or delivered by a concrete pre-mix company. This is a confusing thing with concrete and mostly this is to do with the size stone being used, commonly 19mm, 13.2mm or 9.5mm.
Calculating the amount of concrete needed for footings. Footings will rarely follow the drawing exactly. In rocky soil the footings may collapse when big rocks are excavated. This was supposed to be a 12"*12" footing, but note how the left side of the footing has collapsed. Calculate the true width.
Jul 17, 2017 · Q: What type of footing is required for a concrete block wall? A: To construct a block wall, you need to establish a solid footing that is a minimum of twice the width of the concrete block. For example, a typical 8x8x16-in. block would require a 16-in. wide footing and extend below the frost line.
Concrete can be ordered in ½ yard increments. Slump – Slump is a measure of the consistency of the concrete. A 4 inch slump (the measure of the distance a wet concrete cone will fall) is typical. If you want more slump, it is always safest for the concrete to adjust slump at the plant. Adjusting slump at the job site will damage the concrete.
Your spot on gadgetman if it were a concrete mix. 4:2:1 is 4 parts 20mm stone with 2 parts sharp sand and 1 part cement but as you may well know ballast has 20mm and 10mm stone as well as sharp sand in it with often a random quantity of each.
Your footing should be at least as thick as it is wide at its base. The ideal temperature for pouring concrete is between 50-90 degrees F. Make sure you use 5,000 psi concrete mix. Once you have poured half of the concrete into the tube, you should consolidate it with a shovel or a piece of rebar to eliminate air pocket voids.
To reduce the risk of shrinkage cracks, use Sakrete Crack Resistant Concrete Mix for projects with concrete thickness of 2 inches or greater. It is a professional-strength blend of cementitious materials, sand, stone and fibers that helps eliminate the need for wire mesh in many non-critical applications. Project Tip: Add a touch of color to ...
The mix should be a stiff as possible. Use the largest aggregate practicable. Use the optimum ratio of fines to coarse aggregate. A low water to cement ratio is the number one issue that affects concrete quality. Do not add too much water. Components in concrete Portland Cement - the aggregate and sand is coated by a paste formed from the ...
To calculate grade beam footing first calculate the continuous spread footing required, then calculate the required spot footings and then add together the cubic yards of concrete to determine the amount of concrete required for this type of footing.
A concrete footer is a kind of foundation for structures like outdoor decks, swing sets, and even wooden playgrounds. Pouring concrete footers is one of the first steps to building a strong and sturdy structure because the footer goes into the ground, giving a weighted base which helps keep your project from falling or sinking.
The cost includes concrete bag mix sufficient to fill a 6" x 16" footing (2/3 cubic feet per foot of footing). NOTE-- For a larger hand-mixed pour, you might want to mix the concrete "from scratch" using bulk gravel, concrete sand and portland cement. You might get a slightly cheaper net price, though the increased labor cost and more difficult ...
This Concrete Calculator calculates quantities of concrete materials required for construction of slabs, beams, columns, footings and trapezoidal footings. This Concrete Calculator calculates quantities of materials required for construction of concrete slabs, beams, columns, footings and trapezoidal footings in cubic meters and cubic feet.
Preparing the right mix. Depending on the application concrete mix design can be complex. The below table gives a basic indication of the mix ratios used for different purposes but should be used as a guide only.
Preparing the right mix for solid concrete The most common uses of concrete are for shed floors and footings, bunkers, post footings and stockyards. While the process of laying concrete can be expensive, there are several options for those wishing to carry out the work themselves and save money.

The concrete placement of footing again varies greatly depending on the project circumstances. Sometimes the Ready Mix Concrete truck can run along the footing trench and chute concrete directly into the footings. Other times concrete buggies or wheel barrows need to carry the concrete from the truck to the footing.
Calculate the yards of concrete needed to pour a slab, patio, footing, column, or post fill-project, and estimate the cost of materials. Plus, calculate the number of pre-mix bags needed.
12/19/2019 · Mixing concrete from scratch involves the combination of portland cement, sand, coarse aggregate (crushed and graded stone), and water. The industry standard uses a 1-2-3 formula with one part portland cement, two parts sand, and three parts aggregate for a 4,500-psi mix.

To calculate the amount of material required for foundation concrete mix you first need to calculate the cubic meters of concrete you need using a simple volume calculation, Length x width x depth. It is best to use numbers in meters so for example the a foundation 2100mm x 700mm x500mm would be calculated as, 2.1 x 0.7 x 0.5 = 0.735 cubic meters.
When building any footings or foundations and to ensure a solid footing for any permanent structure like a deck you should always use a structural strength concrete mix if you are getting ready mixed concrete delivered then tell your supplier what you are using it for and they will send you the right mix for your job.
