Since then, we have partnered with them on numerous projects. We like to support other local businesses and first began buying from Keohane’s back in 1980. If you would like to dive in and learn even more about one of the best building materials we have to offer, check out this link for concretes history.In many respects, Cahalane Brothers is very similar to Keohane Readymix in that we are both family businesses that have been in operation for many years based out of West Cork. A few simple ways you can accomplish that are supplying additional moisture with fogging or hooking up a sprinkler, but sometimes you will need to take extra steps, especially in states like south Florida, and cover the slab with plastic after you water it to reduce the amount of evaporation. The need for adequate curing of concrete can not be overemphasized. The curing phase is the maintenance of satisfactory moisture content and temperature in concrete for a sufficient amount of time during and immediately after placing the concrete. Now that you know how much concrete to order and some great facts about it, lets dive into one of the most important if not the most crucial phase of placing concrete. Reusing concrete structures not only is a green thing to do ,but it also conserves future materials and resources and reduces the constrcution time that new structures may require. When appropriately designed, concrete structures can be repurposed and reused several times in the future.

The concrete portion of structures often lasts well over 100 years. However, the actual average life span for a building here in the USA is about 75 years which is more than double the service life. Dependent on the application, most building interiors design service life is 30 years. The longevity of concrete structures around the world has proven to withstand tests of time like the hoover dam completed in 1936 and the Pantheon in Rome, which was completed around 125 AD. There are several types of cement, but the most commonly used is Portland cement.Ĭoncrete durability is its excellent ability to resist weathering, chemical attacks, and abrasion while still maintaining desired engineering properties. The standard amount of time when concrete psi is measured is after 28 days. Cement is an essential material that is used to make all the elements stick together, and it gets stronger and harder over time. So you take your number, for example, 33 cubic feet and divide that by 27, which leaves you with 1.22 yards of concrete.Ĭoncrete, by definition, is a composition of abrasive elements that include gravel, sand, crushed stones, and slag that is fused with cement. A cubic yard of concrete is a 3 foot by 3 foot by 3 foot cube, which has 27 square feet inside of it.

Then we have to convert your cubic foot number to a cubic yard measurement since that is the standard way concrete is ordered.

So following our example above 100 square feet by 0.33 feet, you come up with 33 cubic feet.

Then we multiply the thickness in feet by the square footage to determine cubic feet.

For example, then you would divide that by 12 inches since there are 12 inches in a foot, it gives you the proper decimal conversion. The fundamental way to change inches to feet is to take your thickness of 4 inches. We convert the thickness from inches to feet.

Before you move forward, you need to change your measurement from 4 inches into a decimal representing the footage measurement.

For example, we can use a 10 foot by 10 foot area, which would equal 100 square feet.

After analyzing the thickness, We measure the length and width of the area that needs to be covered in concrete.

The standard thickness is 4″ for most residential applications. Usually, if you are building something new, the engineer on record designates the thickness of the concrete.

First of all, we analyze the thickness of concrete that you need.
