EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 480-4 testing. This European Standard describes a method for determining the relative amount of mixing water that will leak from a freshly mixed concrete sample. This method is valid for concrete mixes containing aggregates up to a maximum size of 50 mm.
EN 480-4 is a European standard that specifies the test method for determining the leaching of admixtures containing concrete. Bleeding is the separation of water from the concrete, which can cause voids or weak spots to form in the finished product.
The test method described in EN 480-4 involves preparing a sample of concrete containing the admixture and placing it in a test apparatus. The apparatus applies pressure to the surface of the concrete sample and measures the amount of water discharged from the surface over a period of time.
The standard specifies the conditions under which the test should be performed, including the temperature and humidity of the test environment. It also provides guidance on sample preparation and the equipment needed to perform the test.
The results of the test can be used to determine the airing properties of concrete, including the velocity of water discharged from the surface and the total amount of water discharged.
EN 480-4 provides a standardized test method for determining the seepage properties of concrete containing additives, helping to ensure that materials used in construction are of consistent quality and meet safety and performance standards. It can also help manufacturers and engineers select the most suitable additives for their specific needs and applications and optimize mix design to minimize bleeding and improve the overall quality of the finished product.
