**Block Masonry Calculation**

In This Article, I will discuss block masonry | the calculation of block masonry | How to Calculate Block Masonry Works.

**What is The Block Masonry?**

**A concrete masonry unit (CMU) is a rectangular b****lock of the standard size used to build a building. Those who use slag (ash or soil ash) as an aggregate material are called slag blocks in the United States, breeze blocks (wind is synonymous with ash) in the United Kingdom, and hollow blocks in the United States and the Philippines.**

**How to Calculate Block Masonry Works**

**Calculation of Blocks Masonry:-**

**Assume 1/2″ thickness of Joint
**

**Area of Wall: 15 x 8 = 120 sq.ft**

Area of One Block: 12.5 x 6.5 = 81.25 or 0.564 sq.ft

No. of Blocks: Area of Wall/Area of One Block – 120/0.564 = 212 Blocks

Area of One Block: 12.5 x 6.5 = 81.25 or 0.564 sq.ft

No. of Blocks: Area of Wall/Area of One Block – 120/0.564 = 212 Blocks

**Finding Mortar In Block Masonry:-**

**Volume of Given Wall: = 15 x 8 x 0.66 = 79.20 Cft**

**Calculation of Mortar:** **15 horizontal and 15 vertical**

**Horizontal Layer:** **= 15 x 15 x 0.66 x 0.0417 = 6.19245**

**Vertical Layer:** **= 15 x 8 x .66 x .0417 = 3.30264**

**Total:** **= 6.19245 + 3.30264 = 9.50 cft**

**Dry Mortar:** **= 9.50 x 1.27 = 12.065 cft**

**12.065/79.20 x 100 = 15.23 per 100 cft**

**Quantity: 79.20 cft**

**Dry** **Mortar:** **79.20 x 15.23/100 =12.06 cft**

** Cement:** **12.06 x 1/7 = 1.72 cft or 1.38 bags**

** Sand:** **12.06 x 6/7 = 10.34 cft**
