How Much Concrete Do I Need?

Whatever you are building, knowing how much concrete to use is essential. To accomplish the task, you should keep the following in mind.

Using a Concrete Calculator

The easiest way to do this is by using a concrete calculator. There are several available on the Internet. What you need to do is enter in the amount (height, weight and depth) in inches. The resulting figure will show how much you should put in.

However these figures are just estimates. Whatever the numbers you see there, add some more to your total. This is to ensure that you don’t come up short when it comes to mixing the stuff in.

Although a calculator is helpful in learning how much concrete to use, it can only do so much. Treat the numbers you see as ballpark figures. While not exact, they can be an aid.

Measuring the Area

Before you can enter the data, you need to measure the site itself. If you are making steps or foundation for a porch, you can use a tape measure. Be sure to get the figures as accurately as possible. For larger projects like bridges, engineers and other personnel will go over the area.

After measuring the area, add 10% to the total. This is for wastage. One important fact to remember: when measuring how much concrete to use, always mix a little more than what is needed.

Pre Mixed vs. Ready Mixed

This is a matter of individual preference. If the project isn’t large, you can mix it on your own. Always follow the directions. This will ensure that the product will be strong and durable. If you don’t want to mix it, ready mix products are available. For those involving 3 cubic feet or more, a concrete mixer may be needed.

Types of Concrete

Cement mixes are generally classified into three groups: regular, high early strength and fiber reinforced.
The regular mix is composed of Portland cement, gravel and sand.

When using this, add wire remesh. Remesh helps ensure that it does not crack. When analyzing how much concrete to use, keep in mind that it should always be used with water. Warm weather is also necessary.

If the weather is cold, high early strength is necessary. It’s basically the same as that of regular mix. The only difference is that an additive is included. The additive makes the hardening process quicker. Fiber reinforced concrete is the same as regular concrete except it doesn’t need remesh.

Safety Precautions

With dry concrete, always wear protective eye gear. There are also dust masks available to shield your face. Wet concrete contains chemicals that may be harmful. Wear gloves and other protective clothing.

Of course, following the instructions on the mix is necessary. Even if the job is small, wear the right clothing. The slightest contact may cause burns or other adverse reactions.

To learn how much concrete to use, getting the dimensions correctly assessed is needed. Combine this with taking safety precautions and you’ll get the job done.
