Tips on Measuring for Concrete

This concrete calculator will help you find out how much concrete you need by cubic yard. Plus, find how muchcover, estimate the slab area for trilateral or octangular shapes and more.

Your measurement methods will shift depending on the human body of your future concrete slab. For example, you ’ ll measure a rectangular shape using duration and width. A round human body requires that you find the diameter .
once you find the dimensions of your slab, input them into the calculator along with the thickness. Enter your project sphere measurements rounded to the nearest foot. If you ’ d rather do the mathematics yourself, merely measure length, width and stature in feet. then multiply these dimensions together. Divide the resulting number by 27 to find the cubic yardage .
once you have your measurement in cubic yards, consult our True Cost Guide for concrete prices .

Different Kinds of Concrete

There are several kinds of concrete available for different home projects. If you ’ re not sure which type to get, don ’ thyroxine hesitate to talk to a concrete pro near you. here are a few common varieties of concrete :

  • Quick-set: Hardens in 20 to 40 minutes. Best for small projects.
  • Regular-set: 24 to 48 hour set time. Used more for large projects.
  • High-strength: Usually sets in 10 to 12 hours. Works well for foundation.
  • Crack-resistant: This is a durable option that works well for walkways.
  • Polymer: Uses epoxy binder to harden. Benefits depend on the type of resin used, but can include heat and weather resistance.

How to Buy Concrete
