Aggregates are used in all aspects of the construction industry to produce bituminous mixtures, concrete, mortars, sub-base materials, railway ballast, etc. They help to make construction materials more compact, increasing their mechanical strength, indispensable in the construction and maintenance of rigid structures.

To evaluate the quality of aggregates, it is necessary to perform a series of tests to determine their properties such as particle size, gradation, specific gravity, and absorption. Your testing equipment must meet the requirements of the Standards and regulations relating to the aggregates used in your mix. Proper maintenance and calibration of your equipment are also necessary to ensure accurate and reliable results.Shear testing machine is used to measure the shear strength properties of soil. Our testing equipment ranges from manual direct/residual shear machines to the automatic electromechanical direct/shear machine, SHEARMATIC EmS.  Also, take a look at the Large Shear Box machine, ideal for soil samples and other materials with large particles. Do you need to obtain residual shear strength by applying a shearing action for a large displacement of the soil sample? The ring Shear machine, also known as Broomhead Apparatus, is what you need. Meanwhile, the Laboratory Vane test apparatus offers a rapid method of determining soft soil shear strength, when an immediate value is required.
