How do you calculate concrete for walls?
Since concrete sells by the cubic yard, you need to divide your wall's volume in inches by 46,656. This tells you how many cubic yards of concrete you need for your wall. For a wall with a total volume of 276,480 inches you need at least 5.9 cubic yards of concrete.
How thick does a concrete wall need to be?
Traditional foundations are constructed of poured concrete or concrete block. A typical foundation wall minimum thickness of eight inches applies to walls eight feet or less with no more than seven feet of soil pressing against it.
What is the minimum thickness of wall?
For all type Building with RCC frame structure, for non load bearing wall, minimum required wall thickness should be 8 inch (200mm) thick for outer wall and to reduce the cost, we can reduce the thickness to 4 inch (100mm) for interior wall partition in RCC frame structure.
How tall can a concrete wall be?
It is not uncommon to create designs with an h/t from 32 to 50. That could produce wall heights of up to 33 feet for walls built with 8-inch concrete masonry units (CMU), 41 feet for 10-inch CMU, and 50 feet for 12-inch CMU. Regionally, 14- and 16-inch CMU are available, which extend possible wall heights even further.
What is concrete mixed into?

Is concrete a perishable product?
Quality – Concrete is a perishable product and should be treated as such. Time, weather conditions including a temperature of the concrete along with ambient temperature and wind speed can affect concrete.
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.
