For the curb & gutter its just a matter of combining the curb and gutter volume using this formula: curb depth * (curb height + flag thickness) * length + gutter width * flag thickness * length, where each component is as illustrated below: A staircase is probably the most complex one, since we need to account for the increasing volume of concrete for each subsequent stair, and also the added depth of the platform on the last step. Yardage of concrete. 2. The Strength of The 10 x 10 Slab You also have to determine the type of concrete needed for your project. Concrete manufacturers often don't specify the density of their concrete mixture directly, but instead give you the bag yield of the material in place. Readymix is pre-mixed concrete to which you only need to add water (in proportion as specified by manufacturer). Use the Readymix Concrete Volume Calculator to calculate the volume of concrete you require for your job. rebar) which provide tensile strength (which concrete lacks on its own) resulting in reinforced concrete. Scroll down for more on concrete density and redymix versus custom mix concrete. With yards of concrete needed to complete a project. Another issue is that the Romans didn't follow a precise mixture, so we'll need years of experimenting to arrive at a good approximation. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. Mr. Concrete is a composite material used for all kinds of construction projects, especially where high compressive strength is required. Click the "Customize" button above to learn more! and 80 lbs. Amount. Cubic Yards to be filled = (L * W * 0.5 / 27); Cubic Yards to be filled = (L * W * 0.67 / 27); Cubic Yards to be filled = (L * W * 1 / 27); Let's be honest - sometimes the best concrete calculator is the one that is easy to use and doesn't require us to even know what the concrete formula is in the first place! While there are many types of cement, Portland cement is the most commonly used cement, and is an ingredient in concrete, mortar, and plasters.

No link. According to the Portland Cement Association concrete with strength between 7000 and 14000 psi is considered high-strength[1]. Guide: One cubic yard of concrete 4" thick covers 81' One cubic yard of concrete 5" thick covers 65' One cubic yard of concrete 6" thick covers 54' The amount of concrete you need varies by project. In the construction industry, you will hear people talking about how many yards of concrete they need, or how many yards they poured. @ 5" thick a cubic yard of concrete will fill an area of 65 sq. Given that there is usually some percentage of concrete lost or wasted during the mixing and pouring process, it is a good idea to consider buying 5-6% more concrete than estimated, to be on the safe side. The volume formula for a rectangular (or square) slab in cubic feet is height(ft) x width(ft) x length(ft), as seen in the figure below: For example, 1ft x 3ft x 6ft = 24ft3 (cubic feet) of concrete required. The volume formula for each particular step is n x step rise x step run x step width, where n is the n-th step.

Note that larger concrete stairs usually have air space beneath them, thus greatly reducing the amount of concrete you need. The calculator uses a standard readymix concrete density by default, but allows for a custom one as well. It is no different for a concrete footing, where we again have the familiar formula h x w x l. A rectangular column is simple to calculate, except in most cases the height will be much greater than the foundation dimensions, so in our concrete calculator we have defaulted to inches for width and length, and feet for the height (cm and meters respectively). 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. If you want your building project to stand the test of time, then a good concrete mixture and estimating the amount of concrete you need are solid first steps. A 60 lb. Polymer-based concretes are seldom used. For example, you need concrete for three stairs that are 8 inches high and 8 inches deep and the total set of stairs will be 1 yard deep and 2 feet across. Calculate for quantity of items to fill for a total project need of cement in cubic feet and cubic yards. 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. Calculate Number of Bags of Premix Concrete needed for Round and Square Footing Holes and Small Concrete Slabs. Round Column Volume Calculator Diameter (inches): Height (feet): Number of Columns: Yards for column: Yards for job: Look for the Sonotube Logo. 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. Two 60lb-bags of concrete cover an area of about 2 square feet for a slab that is 6 inches thick. With yards of concrete needed to complete a project. ft. For a 4" thick slab, 100 sq. Required link back. and divide it by 27 (the number of cubic feet in a cubic yard). Our free Concrete Calculator makes it easy to find out how many yards of concrete you need. Common bag sizes in the U.S. are 80 lbs and 60 lbs bags, while 40 lbs are also manufactured by some producers. If you were pouring 4â concrete youâd need 10 yards for the 800 sq ft (20x40). A calculator like ours is really does a lot of heavy lifting in this case. Calculate the volume of concrete you need in cubic yards. 403–436. This form is more complex and not currently supported by our calculator. Completely settling in place might take several years, depending on climate and other conditions. Calculations - 100/month. ft. / 81 = 1.23 yards of concrete or 56 (80 lb) bags of concrete Estimate the volume of concrete needed, using geometrical formulas and the construction plans. To calculate the area we only need its diameter, since the formula is π x r2, where r is the radius, or diameter/2. Anyone who uses your calculator must enter an email address or phone number. 1. Calculate the volume of your area after determining its shape (see the examples below) by multiplying it with the thickness of the concrete. The second step is (1 yd. A 80 lb. Divide the perimeter by 81 (the number of feet covered by one cubic yard of concrete), and you get 1.234: 100 / 81 = 1.234; So, your slab requires 1.234 cubic yards of concrete. Not all concrete forms are created the same. The final answer is 1.3 cubic yards, but weâre not going to try and get only 1.3 cubic yards of concrete.
