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.

Financial Fitness and Health Math Other. Outer Diameter d 1. Figure driveway 14' x 20' and your estimate will be good. Here is why: The driveway is 16' at the top and 12' at the bottom. Through the center the width averages 14'. Footings will rarely follow the drawing exactly.

In rocky soil the footings may collapse when big rocks are excavated. Calculate the true width. The excavator may have dug too deep, or it may have rained and footings needed to be dug out deeper to reach firm soil.

So it is important to check a variety of spots on your footing and get an average size. Then use the calculator to figure the amount of concrete needed. House slabs on grade that are 8" out of grade with a 4" slab also have some of the footing above the grade too. This 12" x 12" footing needs to be calculated 12" x 16" so the footing is figured to go above grade to reach the 4" slab thickness.

This porch has 9 sq. This totals. The porch also has 9 linear feet of 6" step. So enter in the footing calculator, 6" depth by 12" width always figure steps with a 12" width by 9' length.
