Test of cement on site – Field tests of Cement

Test of cement on site or field tests of cement is one of the most crucial things to be performed to assure the quality of the construction. Every structure is made up of hundreds of different building materials, such as sand, cement, aggregates, bricks, tiles, marble, and so on. However, the quality of the building materials is crucial for producing a high-quality structure and should be regularly evaluated at various phases of construction. Cement is the most important material used in construction and is responsible for the overall strength of the structure. In order to guarantee excellence in building, cement quality must be properly.

This article is about the various test of cement on-site or field tests of cement to ensure quality.

Test of cement on site – Significance

Cement plants are generally found in isolated areas near limestone mines. Generally, clinker is produced by cement companies at a centralised clinkerization plant. Clinkers are either ground at the clinkerization facility or transported to strategically placed grinding units for grinding and cement bag packing. The manufactured and packed cement is transported and delivered to the prescribed destinations by road or rail. Even with the finest protection, the cement still has the potential of absorbing moisture while being transported. After absorbing moisture, the cement tends to harden, deteriorating its quality. Because of these unforeseen concerns, cement must be tested for quality before being used in construction. Basically, cement testing is carried out in accredited laboratories.

How to check cement quality?

The characteristics of cement are often determined by laboratory tests. Lab tests need time, specialised equipment, and expertise to evaluate and interpret the data. All of the cement’s qualities might not be able to be tested on-site. To address this issue, cement tests are divided into two types.

  • Field Tests of Cement

Test of cement on site / Field tests of cement

Some simple field tests can be used to confirm the quality of cement. Generally, these tests do not require the use of costly equipment or professional skills, and the results are obtained quickly. We can determine whether to accept or reject the cement by doing these quick tests, analysing the findings, and drawing conclusions about its quality. These are preliminary evaluations, and the cement’s quality is confirmed by factors such as how smooth it feels to the touch and its colour etc.

Checking the manufacturing date of cement

When stored under perfect conditions, the cement must be utilised within 90 days of manufacture. The manufacturing date and batch number are imprinted on each cement bag. By verifying the manufacturing date, we can get a good indication of how old the cement is and decide whether to use it. In addition, every batch of cement is accompanied by a Manufacturers Test Certificate, which can be requested and examined to verify the dates of manufacture.

Visual checking for Lumps for the test of cement on site.

Cement can be inspected for visible lumps. To establish the potential existence of lumps, you can press the cement bag’s corners. This test determines if the cement has hardened or not.

Feel test of cement on site

Feel a pinch of cement between the figures. Cement has to feel smooth and not grainy. By this test, we can rule out the presence of any adulterated material like sand mixed with cement.

Heat of cement

Put your hand inside a bag of cement that is open. If the cement is of good quality and has not yet begun to hydrate, the hand feels cool.


Cement is usually greenish-grey in colour. We can verify and confirm the colour of the cement on-site. However, the type and source of the ingredients can affect the colour of the cement.

Water float test

This test is performed to find out whether there are impurities in cement. A cement hand is thrown into a bucket of water. The cement floats for a while before settling down if it is good cement free of impurities or other foreign objects. Impurities in the water can cause the cement to settle instantly.

Setting test

A thick paste of cement is applied to a glass piece and slowly immersed in water for 24 hours. The cement piece won’t break or alter shape while it sets and maintains its original shape. This cement is regarded as excellent.


We have the opportunity to contact cement manufacturers through their customer services if we have any questions about the product’s quality and they will be happy to help. It is possible to confirm field observations with laboratory tests. Cement quality should never be compromised during construction. Because the most crucial component that affects the durability and quality of a structure is cement.
