How is the Quality of Concrete Measured?

For Turkey, which is at the forefront of countries that are or will be affected by the earthquake, the quality of concrete is an issue that should be taken into consideration at an undeniable rate.


The quality of the concrete is monitored by determining its strength by breaking the cube or cylinder samples taken while the concrete is fresh after 28 days in the pool. Necessary tests are carried out by taking both concrete producer, building inspection and Ministry of Environment and Urbanization inspection samples from the same concrete and it is determined whether it is suitable for the required strength.


Today, samples taken in ready-mixed concrete production are thrown with chips and these samples are controlled by electronic tracking systems called EBİS. With this feature, it would not be wrong to say that the building material whose quality is the most closely followed is concrete.

Concrete quality is vital, cannot be ignored or risked and a problem experienced in terms of quality reaches irreversible points. The durability of concrete becomes evident 28 days after the concrete is poured, and this shows how important it is to choose a manufacturer.
