Coarse Aggregate Gradation: Test Sieves or Screen Trays?

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.

Characteristics of Aggregates: Shape, Size & Specific Gravity

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.

Aggregate Properties You Need to Know: Strength & Durability

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.

Streamlining Aggregate Gradation Tests: Tips and Tricks

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.

Fineness Modulus of Aggregate

When designing concrete mixes, fineness modulus of the fine aggregate alone is required for effective proportioning of mixes. This blog post explores the process of determining and calculating fineness modulus, and how to accordingly select proportions of coarse aggregate.
