We do tests
We provide full service through sampling according to PN-EN 932-1:1999, sample collection and testing of aggregates in line with the following standards:
- PN-EN 12620 Aggregates for concrete
- PN-EN 13043 Aggregates for bitumen mixes and surface dressings used on roads, airports and other traffic areas
- PN-EN 13055 Lightweight aggregates
- PN-EN 13139 Aggregates for mortar
- PN-EN 13242 Aggregates for unbound and hydraulically bound materials used in construction and road construction
- PN-EN 13450 Aggregates for railway ballast
- PN-S-06102 Car roads
- PN-S-96025 Car and airport roads
- PN-B-11111 Natural aggregates for road surfaces. Gravel and mix
- PN-B-11115 Artificial aggregates made of steel slag for road surfaces
The tests are carried out by experienced and trained employees in the fields of geology, chemistry, ceramics and construction, who use their knowledge and skills every day. We constantly improve our competences, analyze the industry, looking for the best solutions and tests methods.
Many years of experience, commitment, high qualifications, as well as modern equipment allow us to be reliable and comprehensive testing of aggregate. We have accreditation for sampling various types of aggregate. A wide range of tests and cooperation with other accredited laboratories allows for full Client service. Our staff makes sure that each order is carried out in accordance with restrictive standards. We cooperate with producers of mineral aggregates who need to optimize the scope of necessary tests, distributors, recycling companies and laboratories. We provide aggregate testing and control services as part of Factory Production Control (FPC) and help with its implementation and in obtaining certificates of compliance, e.g. from the Railway Reasarch Institute (IK). Following the needs of our Clients, we issue certificates of compliance with the standard requirements, as well as we carry out all the necessary tests of aggregates to obtain CE mark.
Testing aggregates for concrete
Testing aggregates for concrete is extremely important because they affect the later usability of this building material. Aggregates of natural and industrial origin and recycled aggregates are used for concrete. Each of these aggregates must undergo appropriate tests so that it can be used in the production of concrete for various applications. The requirements for concrete aggregates are referred to in the PN-EN 12620 standard. The most important parameters that are defined for concrete aggregates include: grain size, dust quality and content, aggregate shape, density and water absorption, frost resistance or the content of chlorides and sulfur compounds. An equally important parameter is the alkaline reactivity of the aggregates. Alkaline reactivity can be performed in our laboratory according to various standards. Currently, the most popular tests of aggregate reactivity are the trabecular methods referred to in procedures PB/1/18 GDDKiA - short-term method and PB/2/18 GDDKiA - long-term method. These are procedures created and required by General Directorate for National Roads and Motorways. These and other important tests can be found in our extensive laboratory test offer.
Test of road aggregates
We carry out tests of road aggregates that must meet the requirements of the PN-EN 13242 standard. In road construction, aggregates optimally selected for the investment are used as road durabilityand safety of their users depend thereon. Most often, construction aggregates with appropriate graining and resistance to weather and erosion factors, i.e. frost resistance, resistance to grinding and abrasion, are used for the construction of this type of investment. These are natural, artificial and recycled aggregates. We are able to test all these aggregates and determine whether they are suitable for use in road construction. For comprehensive service, we can also take samples of aggregates in accordance with the PN-EN 932-1 standard. Correct sampling is the most important element of the research process, often determining the result of subsequent tests. We invite you to use our services.
