Does the particle size analysis of coarse aggregates always require a testing screen with large screen trays? In a situation where larger testing equipment is not available, there may still be ways to get the job done. Using conventional round test sieves for large particle sizes is less efficient, but still acceptable if done properly. We discuss test requirements, sieve capacities, and tips to help with equipment selection.

Fines and dust in asphalt and concrete aggregates have always been a problem. Whether naturally occurring or resulting from degradation during handling and transport, undesirable or unknown amounts of fines can impact the performance and cost of composite materials. This blog post discusses the importance, process, and procedure.

In this month's blog, we examine the civil engineering laboratory equipment needed for typical operations performed where field laboratories for construction materials testing are required. With so many possible variations in specific project requirements, we break it down by application.

In this blog, it will discuss setting up and furnishing temporary field-testing labs with essential laboratory equipment. Field labs are generally limited to a few particular tests, but no matter the material, most require the same essentials to measure properties like size, weight, and moisture.

The selection of the best jaw crusher for your application will naturally be governed by the particle size, volume, and properties of your bulk material, along with the desired particle size and quantity of the final sample. In this blog, we help you select the right jaw crusher for your testing application.

Concluding our two-part series on aggregate characteristics. Find out how shape, size, and specific gravity play a part in determining the effectiveness of aggregates in construction projects.

Soundness, toughness, and durability are all critical components to the effectiveness of aggregates used in construction. In part one of our series on aggregates, you’ll get an insider’s look at their strength properties, the methods of testing, and how to select the proper equipment for testing.

High decibel levels can potentially be a dangerous element in your materials testing lab. In part two of our special series on workplace safety, you’ll discover some of the best ways to reduce noise levels during testing.

In part one of our special series on workplace safety, we take a look at how advances in materials testing equipment are minimizing potentially harmful exposure to dust in the lab.

Sieving for particle size distribution is the primary test requested for construction aggregate samples. Whether field samples are being tested to evaluate a new aggregate source or just coming in as part of day-to-day quality control of production, particle size distribution is a primary consideration. If processing and sieving is not handled efficiently, it creates a backlog.
