CHAPTER 4. REINFORCED CONCRETE Slide No. 3 ENCE 454 Assakkaf Steel is a high-cost material compared with concrete. It follows that the two materials are best used in combination if the concrete is made to resist the compressive stresses and the steel the tensile stresses. Concrete cannot withstand very much tensile stress without cracking.

How to Calculate the Number of Cement Blocks for

Step 5. Calculate the number of blocks required by substituting the area to be built and the size of the block in this equation: total area of walls / area of a block = number of blocks required. To conclude the example, building 2,100 square feet of wall from 0.89-square-foot blocks requires 2,360 blocks — 2,100 x 0.89 = 2,359.55.
