Purchasing slightly more concrete than the estimated result can reduce the probability of having insufficient concrete. Related Volume Calculator. Concrete is a material comprised of a number of coarse aggregates particulate materials such as sand, gravel, crushed stone, and slag bonded with cement. Cement is a substance that is used to bind materials, such as aggregate, by adhering to said materials, then hardening over time.
While there are many types of cement, Portland cement is the most commonly used cement, and is an ingredient in concrete, mortar, and plasters. Concrete can be purchased in multiple forms, including in 60 or pound bags, or delivered in large amounts by specialized concrete mixer trucks.
Proper mixing is essential for the production of strong, uniform concrete. It involves mixing water, aggregate, cement, and any desired additives.
Production of concrete is time-sensitive, and the concrete must be placed before it hardens since it is usually prepared as a viscous fluid. Some concretes are even designed to harden more quickly for applications that require rapid set time. Alternatively, in some factory settings, concrete is mixed into dryer forms to manufacture precast concrete products such as concrete walls.
The process of concrete hardening once it has been placed is called curing, and is a slow process. Ensuring that the concrete is damp can increase the strength of the concrete during the early stages of curing.
This is achieved through techniques such as spraying concrete slabs with compounds that create a film over the concrete that retains water, as well as ponding, where concrete is submerged in water and wrapped in plastic.

Enter your preferences below and then, use ImproveNet to connect with an experienced fencing contractor near you.
When many of us picture the American Dream, a wood fence is surely in the portrait. Beyond adding that sense of privacy we all want in our home, a new fence, no matter the material, increases the value of your home, deters intruders, keeps pets and children nearby and helps eliminate outside noise.
Why you install a fence is easy. How much wood fencing you need is another obstacle all together. Luckily, you've come to the right place. Use our wood fence calculator above to determine exactly how much wood you need for your new fence. Once you enter all your specs, you'll see how many post, rails and boards are required. Of course, these numbers will go a long way in determining your final wood fence installation cost.
As you can see above, there are a lot of factors at play. To make it as easy as possible to calculate how much lumber you need for your new wood fence, keep the following fencing basics in mind:. If you're brand new to a wood fence installation, follow the steps below to ensure you buy the correct quantity of all materials:.
Preparation: Check with your city so you know exactly where you can and can not install the fence. Also, see if you have to pull permits. Then, call so they can mark your property and utility lines. This ensures you don't cut electricity for the entire block.
Sketch the Fence: Lay out your fence with stakes at each corner and string in between. Then, use a long tape measure to determine your total wood fence length. Number of Posts: As we said earlier, posts should be no longer than 8 feet apart from each other. Some homeowners go with 16 feet, but if you do, your fence will not be as sturdy. If you go with 8 feet, divide your fence length by 8 to get the total number of posts. Therefore, a foot fence would require 12 posts.

Wiki User For 90 degree fittings divide the diameter by 2 then add quotion to original diameter for 45 degree fittings multiply.
Related Questions Asked in Geometry What is the take off formula off 45 degree elbow pipe? The take off formula of a 45 degree elbow pipe, will depend on what the pipe is on.
Sometimes a 45 degree pipe will need a 90 degree right angle turn to come off. There is no one formula for fitting take offs.
The general rule used for gal and black malleable fittings is on a center to center measurement to take off the ID of the pipe you are using on each end of the pipe.
Example if center to center measurement is 10 feet between a 1 inch tee and a 1 inch 90 ell. The end to end measurement would be minus 2 inches for a total of 9 foot 10 inches.
If you are a industrial pipe fitter there is a pipe fitters blue book that covers all this and a lot more,but the formula we use is take the size of the fitting and break it down 4 times add the second and forth dimension together and there's your take off,ex.

This radius will vary depending on the outside diameter of the tube, the wall thickness, and the angle at which the tube is to be bent. It is important to understand the different elements of a bend in order to make accurate calculations. Using the same variables as above, the standard dimension ratio SDR of a pipe can be calculated thusly:. A simple way to determine the center line radius of a bend of a specific angle is calculate a full circle, then divide that number by to find the measurement of one degree.
Then, use this formula:. For example, if your die creates a 2.
The black line represents an offset bend in a tube; the red triangle represents the triangular geometry this offset creates. The relatively simple math formulas of sine, cosine, and tangent can be used to determine the angles of the triangle, and, therefore, the necessary angles of your pipe bend s.
Most scientific calculators and even the calculators built into smart phones have these functions. View information about bending conduit using a bender and the deducts and multipliers charts.

Elements of a Bend It is important to understand the different elements of a bend in order to make accurate calculations.This process is known as takeoff — or material takeoff MTO — and is an essential part of the estimating process.
For a small one-off job, an experienced builder should be able to estimate the materials required in his or her head. A more thorough process is necessary for major construction projects, however.
It is important to approach the task in a methodical manner in order to achieve the most accurate approximation possible. As well as providing a precise estimate for yourself and your client, this will also help the job run smoother on the ground by ensuring that your workers or contractors have everything they need. It is worth noting that, while a thorough takeoff will improve your estimate, there will be other factors to take into account.
These include your office overhead costs, shifts in market prices for materials, and various other expenses. What to count. Essentially, the takeoff should quantify all the materials needed to complete the building, structure or project. This does not include assets such as tools and equipment, which are also required to do the job but should include all the physical materials that go into the project.
This could be raw materials such as concrete, timber or sand, as well as prefabricated materials; bricks, lengths of electrical cable, plumbing pipes, and light fixtures. Looking to improve your estimating skills? In addition to counting the materials, the MTO should also specify the type of material required.
This could be the grade of steel or the type of electrical cable, for example. Different contractors might have a diverse range of requirements when it comes to compiling their takeoff. A roofing specialist will use different materials than a concrete contractor, for example, but the principles of takeoff are broadly the same. There are four key types of measurement required for the takeoff in most construction projects.
The estimator will need to count the numbers required for specific individual items. These could be anything from the number of light fixtures required for a given building to the number of studs necessary to finish the project.
Some items, such as cables and pipes, are measured primarily by length. You will also need to know other dimensions, such as diameter, but this information will be included with the type of material required. You might need to allow for extra amounts for elements such as drops for switches, receptacles, and panels when measuring electrical cable. Some materials will require a measurement of the surface area. This could include elements such as flooring, cladding, or an estimate of the amount of paint needed for a given structure.
Measurements of volume may be needed for some materials, such as the amount of asphalt used per yard or the concrete required to lay a foundation. There are two main types of takeoffs.Piping Double Rolling calculation - Updated
However, it is crucial that the estimator be able to accurately read blueprints and plans for the type of work being quantified general building plans, electrical and plumbing schematics, etc.
