Mortar testing is a crucial procedure in the field of masonry construction, which involves examining the physical and chemical characteristics of mortar – a workable paste made from a mixture of sand, a binder (such as lime or cement), and water. Mortar serves as a binding material between masonry units like bricks and blocks, thus making its quality and properties essential for the structural integrity of masonry works.

The primary aim of mortar testing is to assess its suitability for masonry construction. This involves the evaluation of various properties such as compressive strength, bonding strength, water retention, air content, and consistency. These properties directly affect the performance of the mortar in terms of its workability, bond formation with masonry units, durability, and resistance to environmental impacts.

Mortar testing provides several benefits. Firstly, it ensures the quality of the mortar used in a construction project, thereby promoting safer and more durable masonry constructions. Secondly, it helps in optimizing the mix design of the mortar, which can enhance the performance and longevity of the structures. Lastly, it contributes to cost savings by minimizing the chances of failures or costly repairs due to inferior quality mortars.

Mortar testing should ideally be carried out before the mortar is used in construction, during its production process, and also when it arrives at the construction site. This guarantees that the mortar maintains its quality throughout the construction process.

Below is the list of the most common cement tests that we undertake for our clients. All our tests are undertaken in accordance with either the British Standard of ASTM:


  1. Compressive Strength Test: Determines the maximum load a mortar sample can bear before breaking.
  2. Bond Strength Test: Measures the strength of the bond formed between the mortar and masonry unit.
  3. Water Retention Test: Assesses the ability of the mortar to retain water, which affects workability and bond strength.
  4. Air Content Test: Measures the volume of air trapped within the mortar, which can influence workability and durability.
  5. Consistency Test: Evaluates the workability or ease of use of the mortar.
  6. Soundness Test: Assesses the potential of the mortar to expand and crack.
  7. Setting Time Test: Determines the time taken by the mortar to start setting and completely set, which affects the workability period.
  8. Autoclave Expansion Test: Evaluates the potential of the mortar to expand under high pressure and temperature conditions.
  9. Freeze-Thaw Test: Assesses the durability of the mortar under freeze-thaw cycles.
  10. Sulphate Resistance Test: Evaluates the ability of the mortar to resist sulphate attacks, which can cause degradation and loss of strength.
