Cement blocks can be purchased in various sizes and shapes, but for most steps you can use standard-size cement blocks that are 8 inches wide by 8 inches high and 16 inches long. These dimensions will work out well for most stairs since you will usually want risers about 8 inches in height.
How do you lay a breeze block for beginners?
How do you calculate concrete block steps?
How to calculate concrete blocks needed? Substitute the numbers in the equation square feet of block = (length x height) / 144 for the length and height of the block in inches. A normal cement block, for example, measures 16 by 8 inches and covers 0.89 square feet (16 x 8) / 144 = 0.89.

What is the formula for laying out stairs?
You divide the height by 7 inches; if, say, the floor-to-floor distance is 8 feet, 10 inches (or 106 inches), then you’ll need 15 treads (106 divided by 7 equals 15.14). Next, you divide the height by the number of treads (15 into 106), producing the exact tread height (7.06 inches).
How do you lay a block on the ground?

Mortar and mortar joints
The mortar joints used in concrete block and brick construction are usually 10 mm thick. For AAC block construction, a special type of mortar is used (2-3 mm) and this is a pre-mixed cement-based product with higher quality than normal mortar.
Should mortar be harder than blocks?
“Mortar should never be stronger than the bricks” is a well-known maxim in the bricklaying world. In this context, “stronger” does not mean its load-bearing capacity, but the mortar’s hardness and permeability. Hard, dense mortar should not be used to surround porous, open-textured bricks.
Is it better to drill into block or mortar?
Mortar is easier to drill through because it’s a softer substance than brick and is also easier to patch or repair. Drilling into the mortar with a screw expansion plug or another fastener will cause the anchor’s force to push against the intact bricks instead of expanding the material.
