As a non-traditional, non-destructive analysis method, the Acoustic Emission Method was used for civil engineering experiment. Concrete is a composite construction material frequently used in civil engineering. We know that concrete is as a man – when concrete is made it is as a baby, then it ages and its properties change in accordance to its baby life. That means it is better to monitor and change its properties when it is young as soon as possible. However, using the methods immediately after concrete birth (making the mixture) is difficult. The main aim of the article is to show the application of Acoustic Emission Method during concrete lifetime, particularly during the first days after mixing the mixture. Article describes monitoring concrete structure from their making up to a lot of month. Primary interesting part is during first day of hardening. Acoustic Emission Method has used for monitoring both samples. Expected result has been between covered and uncovered specimen.
