Volume Of Concrete For Steps: Volume of one step = 1/2 x riser x tread x length of step = 1/2 x 0.5 x 0.8 x 5 = 1.03 = 1 cubic feet. As we have 11 steps in a flight the volume of steps for the first flight = 11 x 1 = 11 cubic feet.

Concrete Calculator for Stairs with Landing (solid)- Imperial
This is not a very efficient way of building concrete stairs. I can see someone building stairs this way with 2 steps, but for more steps you would be better off building an inside box to limit the amount of concrete needed.
When Ordering Concrete
This concrete calculator will help you in estimating the amount of concrete needed for your project. The amount given as needed, does not include any waste. It is recommended, depending on the job you are doing, to add anywhere from an extra 4% to 10% to your concrete order to make sure you have enough concrete to finish the job.
How is concrete volume measured?
Familiarize yourself with how concrete volume is measured. Concrete's volume (the amount of physical space it takes up) is typically measured in either cubic yards (yds 3) or cubic meters (m 3 ). A cubic yard is a 3-dimensional cube that is 3 feet long in each dimension, while a cubic meter is a cube that is 1 meter long in each dimension.
How to find the square footage of a concrete job?
ft" or ft 2) is a measure of 2-dimensional area typically used to describe floor space. To determine your concrete job's square footage, simply multiply the length and width of the area you're pouring into without taking into account its depth.
How to calculate cubic yards of concrete?
There are 27 cubic feet in a cubic yard, so, to convert to cubic yards, we can divide by our cubic feet value by 27. The slab's volume is 39.6 / 27 = 1.47 cubic yards. Alternatively, since there are three feet in a yard, you can divide each individual foot measurement by 3 to get yard values and then multiply these together to get the same answer.

However, if you need to pour a slab along with 4 straight walls, each wall would be its own prism, resulting in a total of 5 prisms.
How to find concrete yardage?
Now that you've found your square footage, all you need to do to find your project's concrete yardage is to divide the square footage by a certain number - the thicker your project, the smaller the number; the thinner your project, the larger the number.
How to find odd coefficients?
If the thickness of your concrete pour doesn't match any of the examples above, you can quickly calculate it by dividing 324 by the thickness of your concrete project (in inches). Then, divide your square footage by your answer to find your project's yardage.
Calculator Use
Calculate volumes for concrete slabs, walls, footers, columns, steps, curbs and gutters. Enter dimensions in US units (inches or feet) or metric units (centimeters or meters) of your concrete structure to get the cubic yards value of the amount of concrete you will need to make this structure.
Curbs & Gutters
We calculate the volume in sections from the ground to the top of each section. The Curb and Gutter are each a section.
How to identify steps built over wells?
You don’t want to start busting up the old steps and suddenly find yourself in the basement covered in rubble. You can identify steps built over wells by a glass access panel built in. Sometimes the panel has been broken or removed, but the patch should still be visible. Don’t even think about starting the demo process without asking the homeowner or preferably paying a visit into the basement and investigating with your own eyes.
What to do with extra bucket of concrete?
Keeping an extra bucket of concrete on hand is a smart move. It will come in handy to if you need to fill any voids that may be lurking behind the form boards. Keep the bucket covered and out of the sun.
How to eliminate voids in concrete?
Eliminate the smaller voids by tapping on every part of every form board. More taps with a smaller hammer is better than a few taps with a big one. Big hammers can send concrete flying all over the place. You can’t overdo this step, especially since the stoop is being poured dryer and will be less willing to conform.
Why do you pour concrete wet?
The reason for this is that a thick pour will exert less pressure on the form and allow you to dismantle it sooner than later. Pouring the sidewalk wet will also give you time to let it sit while you are working on the steps. wet sidewalk pour also provides extra cream, which can be rubbed on the vertical faces of the concrete to smooth them out once you start pulling forms (see below).
Can you put concrete on a house?
It’s okay if some of the old concrete sticks to the house. But it’s important to clean off the top area or it will show, especially if the new stoop is going to be poured at the same level or lower than the old one. Knock off the remnants with a hammer and cold chisel.
Can you put a stoops in concrete?
Stoops are not one solid monolithic hunk of concrete, or at least they shouldn’t be. You are going to need some fill in the center, so you might as well leave the concrete you just busted up in place. Remove or reduce any chunks larger than a football.
Can you leave tools face down on concrete?
Building concrete steps requires a whole bunch of switching back and forth between edgers and mags. One trick a lot of pros have figured out is that if you leave the tools face down on the concrete they don’t dry out as fast. A tool covered in dried chunks of concrete is good for nothing.
