Cement Life : Does Old Cement Loses strength? Find out the Answer

Cement Life:  Cement is the first material that we think of when we want to build a house or any other structures. There are many construction materials which are used to construct a house or building but cement has a major role to play with respect to its life, strength and cost. its own valuable impression

Fresh cement has many benefits. Fresh cement only leads to the good quality of construction which ultimately results into the longer service life of the building. But cement which is stored in godown for a longer duration, out dated cement or cement which is stored on site for a longer duration may lead to the poor quality of construction.

Cement Life : Does Old Cement Loses strength? Find out the Answer 1

Though the cement might be well protected in the cement godown, it absorbs moisture from the atmosphere and over a period of time, cement loses its strength. So, a million-dollar question is does cement loses its strength over a time?

Yes, Cement loses its strength over a period of time.

Cement is available in the form of a very fine powder and it has a tendency to absorb moisture from the atmosphere. When it absorbs moisture, it hydrates, and consequently the use of that cement does not contribute to the strength development or it contributes less.

Such cement gets hardened and form lumps. Hence one gets confused whether one can use such cement? or how old cement one can use?

Generally, cement is bagged in multi-wall paper sack. Multi-wall paper are neither airtight nor damp-proof and also do not prevent absorption of moisture.  Vice versa cement bagged in woven polythene or craft papers are not likely to deteriorate fast to the extent mentioned above. The loss of strength also depends on the condition of the godown.

To know more how the moisture can affect the quality of cement, read the effect of moisture on cement bags.

The loss of strength of cement at different interval of times as reported by major studies is as given below in the table

Note that the Strength of any concrete structure majorly depends on strength of the cement. If you use the fresh cement (at least 3 month old cement), it imparts high strength to your structure and makes it long lasting. Uses of old cement therefore can lead to various problems such as development cracks, leakages, corrosion etc. which will increase your maintenance cost and reduce life of your structure.
