Cinder blocks are less expensive to work with than poured concrete in home construction projects but they are not as strong you can make up the difference by spending a little more to reinforce the blocks a project that is still less expensive than using just poured concrete.
How much concrete to core fill a block wall.
When reinforced with steel and filled with concrete a rock solid wall can be built to withstand the elements.
Whenever you are working with cinder block you can strengthen them significantly by filling them with concrete.
To use the block wall calculator simply enter the height and length of the wall click on whether you are filling an 8 inch or 12 inch wall then click on the calculate button.
Concrete block also known as a concrete masonry unit and sometimes called a cinder block typically has one or two holes or voids to reduce the weight of the block.
The calculator will estimate the number of cubic yards that will be required.
Contractors elect to fill the hollow openings or voids in concrete blocks sometimes referred to as grouting after they are stacked or laid to achieve a stronger wall one with properties nearly identical to a poured concrete wall.
To estimate how much grout is needed to fill those voids you need to find the volume of each void and multiply that by the number of voids in the wall.
The hollow core of each concrete block keeps it from weighing too much to work with and provides a cavity that can be filled with concrete for added strength.
Given that your measurements are 2 x2 x4 the block contains about 16 cubic feet.
For smaller projects and those poured by hand some type of funnel.
