Share. In a perfect universe, our 1,080 square foot driveway will need exactly 16.62 cubic yards of concrete (1,080 square feet / 65 square feet equals 16.62 cubic yards). Download: Use this concrete calculator offline with our all-in-one calculator app for Android and iOS. All calculators on this site are geometric only. The concrete converter can be applied in construction and structural engineering for exchange from volumes of concrete quantities into their equivalents in mass. How Much Concrete Do You Need? Answer: Boxing shores or props underneath need to be in place as to support the heavy concrete. All Inch inputs and dimensions are actual physical finished sizes, If the US ever goes Metric, you'll be able to use a Meter to measure Meters - A Meter Meter. The concrete calculator is calibrated to exactly 23.60 kN/m3 unit weight per concrete volume. Pre-Mix Concrete Bag Calculator Calculated at 2160 kg per 1m³ - Allow extra for waste Cubic Metres 20 kg Bags 25 kg Bags 30 kg Bags 40 kg Bags @ $ per bag Zoom to adjust screen scale to actual size (measure full scale diagram with ruler) and hit 'Set' to set scale on other pages. Completely settling in place might take several years, depending on climate and other conditions. A cubic measurement is the three-dimensional derivative of a linear measure, so a cubic foot is defined as the volume of a cube with sides 1 ft in length. This same principle applies when dealing in metric. Entering measurements. Which is, as Internationally defined, how heavy is normal reinforced concrete. If you'd like to link to me, please highlight > cut > paste the following code into your web page. You can also estimate the quantity of sand and gravel required by weight; Simply multiply the volumetric quantity of sand and gravel with 1400 kg/m3 (bulk density of sand) and 1600 kg/m3 (bulk density of stone) respectively, when calculating in metric units. Cubic Feet. Use the Readymix Concrete Volume Calculator to calculate the volume of concrete you require for your job. Calculate the amount of concrete needed in cubic feet and cubic yards for a slab in the shape of a circle. Count with ~5% weight reduction once water evaporates. A cubic meter, or cubic metre in British English, is a measure of volume for a cube that has a length, width, and height of one meter. Question: Why do technical drawings ask for shoring wile the floors set if fresh wet concrete does not weigh significantly more than dry concrete? We realise this can be confusing, so to help you convert inches for depth into feet please see the information below. Simply add the measurements for your concrete order to the relevant shapes above (you only have to fill in the shape/s you want to use) You can build up a concrete calculation for complicated areas by adding additional shapes of each type. Use our online Concrete Driveway Calculator to calculate how much concrete is needed for a driveway. Weighing concrete in tonnes per cubic meter or kilograms kg, lb pounds per cubic foot or yd yards. Calculate concrete volume of a square slab. For example, when using feet to enter dimensions you must enter 10 feet x 6 feet x 0.5 feet (for 6 inches). We know measurements can be a real hassle, when laying concrete - and if not done correctly, the results can be far from what you expected. Use this calculator tool to convert between square feet and cubic feet. The most typical value widely used is 150 lb/ft^3 for the most common/ordinary concrete strength at ~ 4,000 psi = 4000 lbf / (sq in). Formula and Image for square shaped concrete block: Square Slab - Concrete Block. If you've benefited from this free service please consider supporting: Calculated at 2160 kg per 1m³ - Allow extra for waste. Volume in Cubic Meters (m 3) = Volume in Cubic Feet (ft 3) x 0.0283. You have 8.33 cubic yards (6.37 cubic meters) of concrete that will be poured in this example. Click Slider to select then use keyboard cursor keys, Create and Print Full Scale PDFs with diagrams on this page (templates), Copy all diagrams on this page to bottom of page - Make multiple copies to Print or Compare Results. On this page, you can calculate material consumption viz., cement, sand, stone gravel for the following concrete mix ratios - 1:1.5:3, 1:2:4, 1:3:6, 1:4:8, 1:5:10. Even though the aggregate is denser and heavier than water (4 parts of the aggregate is contained within the concrete - add 1 part dry cement + water, 4:1 always in volume sense is the usual standard concrete mixing ratio), wet fresh concrete before it sets will not be much heavier nor lighter per volume unit because the water presence is adding to its total weight. The same measurement format must be used for length, width and depth. The same measurement format must be used for length, width and depth. Though, to be exact, there is the marginal drying shrinkage caused by the water evaporation from the fresh concrete which causes a slight weight difference between the soft and set concrete state ... read further down. The main Navigation tabs at top of each page are Metric - inputs in millimeters (mm). Once, the quantities are determined, it is easy to estimate the cost of a concrete block, driveway, patio, yard or any other structure with the price prevailing in your area. To find the amount of ready mix concrete for a slab, you can estimate it with a standard volume calculator. It is not possible to enter 6 for depth as this will calculate 6 feet not 6 inches. Free calculators and unit converters for general and everyday use. It is composed of fine and coarse aggregate which are bonded via fluid cement paste that hardens over time - usually about a week to reach over 50% of its final strength and a couple of weeks to reach 95% of it. In metric terms a cubic foot is a cube with sides 0.3048 metres in length. Formulas used: Area A = π * D² ÷ 4 You may enter whole numbers, decimals or fractions ie: 5, 75.33, 45 1/4. Later it sets and hardens. Price (Optional) foot (ft³)yard (yd³)meter (m³)$€£₹元¥R¤. To calculate a volume in cubic meters, start by measuring your space. Calculated at 2160 kg per 1m³ - Allow extra for waste. Please, Zoom out to fit large full scale template images on screen - or to adjust scale to match ruler held against screen. Concrete Calculator. 6783/1728 = 3.93 cubic feet. Please note that this concrete calculator can only use one unit denomination of inches, feet, millimetres, centimetres or metres. Built something using our calculators? Which is important to know about, very easy to solve, how to deal with this was fully covered in previous pages. The difference in weight between wet runny concrete just mixed and the concrete in a solid state? Extensive list of concrete measuring units. Explore other calculators related to housing or building, as well as hundreds of other calculators addressing finance, math, fitness, health, and more. If you are not sure of how to calculate the volume of different shapes, you can use the Common Shape Calculator which will provide you with the appropriate equations. To calculate the concrete volume needed for this type of slab, you need to know the circle's diameter and the depth of this slab. *1m³ minimum order value. This would be good to know if you had a lot of sono-tubes or a large cylinder to fill.
