The scope of this test is the determination of the effect of aggregates on the drying shrinkage of concrete. The test is based on the testing of concretes of fixed mix proportions and aggregates of 20 mm max. size. The instrument consists of an analogic or digital dial gauge which is mounted on a steel frame.

The top anvil is adjustable to suit the required specimen. The three gang mould, 50x50x200 mm size, is made of steel and is complete with steel inserts.

The set includes length measuring frame, three gang steel mould according to the related standard and reference rod. The set is available in two models one with 0,002mmx10mm analogue dial gauge, the other one with 0.001mmx20 mm digital dial gauge.

The Shrinkage and Expansion Test Set, designed and produced to calculate the changes that will occur in the dimensions of concrete prisms, works with the main principle of the autoclave method. Thanks to this device, the expansion and contraction values of the concrete piece sample can be learned instantly and it is an extremely important device for examining the shrinkage and expansion changes of the concrete sample.

The Shrinkage and Expansion Test Set, which is used to examine the length change of 40x40x160 mm and other sizes of cement prisms with the autoclave method, that is, accelerated expansion, is presented to you, our customers, as two different models.

One of them is the Analog Comparator Clock with a height measuring frame of 0.002mmx10 mm precision, while our other model has the options of 0.001mmx20 mm Digital Comparator Clock. Our Shrinkage and Expansion Test Set device meets all national and international standards and makes the most consistent and reliable measurements in accordance with all standards.

Contraction and Expansion Test Set Features

There are points to be considered about the working principle on behalf of the Contraction and Expansion Experiment Set. In the experiment to be carried out for the cement prism, measurements can be made using both digital and analog. You can choose one of these two models, whichever way of use is suitable for you.

The main purpose of the Contraction and Expansion Test Set is to determine what size the cement prism sample mortar will gain after drying and how much it will differ from its original size. For this, the accelerated expansion method, which is called the Autoclave method, is applied in the most effective way thanks to this set of experiments.

After the results obtained with this set, which has a very important function in terms of examining the expansion conditions of cement prisms and the size change that occurs as a result of expansion, other test steps can be safely passed.

You can have the Contraction and Expansion Test Set, which is produced in accordance with EN 1367-4 standard and offered to you in the highest quality with the assurance of Argon Test, at the most affordable prices.
