What is cement mortar?
Cement mortar is the most used material in the construction area, and it comes in a paste state. It is a mixture of cement, fine aggregate, and water. Cement is the main bonding component in a mortar with the help of water. Lime mortar is also used in construction, cement is replaced and lime is added. The lime mortar is a mixture of lime, fine aggregate, and water.
Uses of cement mortar
Cement mortar is a binding material, it is mainly used to bind construction materials like bricks, stones, and concrete masonry work and fill inside the brick masonry and seal irregular gaps between them, elevation decoration, elevation patterns to surface and masonry walls, plastering, some architectural design, etc…
Design mix ratio
Design mix, the proportion of cement and fine aggregate
- CM 1:1
- CM 1:2
- CM 1:3
- CM 1:4
- CM 1:5
- CM 1:6
- CM 1:8
Where, CM = Cement mortar, x:x = Cement : Fine aggregate
Materials required for 1m3 cement mortar, ratio CM 1:1
CM 1:1 = Cement mortar 1:1 (cement: fine aggregate)
Cement
= ((part of cement) / (sum of ratio)) x total volume required
Part of cement = 1
Sum of ratio = (1+1) = 2
The total volume required = Wet volume x dry volume
Wet volume = Actual required volume
Dry volume = 1.33 (for mortar)
What is dry volume?1.33? CLICK HERE
Total volume required = 1×1.33 = 1.33
= (1/2) x 1.33= 0.665 m3
Unit weight of cement = 1440 kg/m3
= 0.665 x 1440 = 957.6 kg
= 957.6 / 50 (1 bag cement = 50kg)
= 19.152 bags of cement required
Fine aggregate
= ((part of fine aggregate) / (sum of ratio)) x total volume required
Part of Fine Aggregate = 1
Sum of ratio = (1+1) = 2
Total volume required = 1×1.33 = 1.33
= (1/2) x 1.33= 0.665 m3
Unit weight of F.A = 1600 to 1840 kg/m3
take 1600= 0.665 x 1600 = 1064 kg
Water
Assume water-cement ratio = 0.50 (50% of cement)
= 957.6 x 0.50
= 478.8 kg
= 478.8 litres ~ 479 litres of water required
Summary
Material required for 1m3 mortar CM 1:1
- Cement = 19.152 bags (1 bag is 50kg)
- Fine aggregate = 1064 kg
- Water = 479 litre

Note
- Add 5 to 15% wastage (optional, if required then you can add wastage)
- The above values are changed. If the quantity and quality of material change or the unit weight change
- The water-cement ratio depends on the requirement of strength and workability (not the same for all requirements)
