Soil Hydrometer Testing: Sedimentation Method Techniques & Equipment

Measuring the particle size distribution of fine-grained soils like clay and silt is best performed using the soil hydrometer test. In this blog post, we provide some guidance from sample prepping to performing the test procedure by following the ASTM D7928 standard test method.

Inventing the Sonic Sifter: How a New Cafeteria Changed the Sieving Industry

Most materials have a lower size limit where sieving with a sieve shaker is no longer sufficient, and the agitation necessary for particle separation starts to break down and destroy some fragile materials. Particles in some substances resist separation and clump together due to electrostatic or moisture issues. For many years, these problems limited the effectiveness of measuring particle size by sieving. This article tells the story of how one man pushed back those boundaries.

Sonic Sieving: The Solution for Particle Size Problems

Test sieves are an efficient, productive, and economical means of characterizing the gradation of dry granular materials. However, the sieving method is not without limitations. If obstacles seem to be making it difficult to produce accurate, repeatable results for finer sizes, Sonic Sieving may be the answer.

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.

Selecting the Right Test Sieve for Non-Conventional Use
Selecting the Right Test Sieve for Non-Conventional Use

Testing sieves are not a one-size-fits-all product in materials testing. They should be selected based on application, compliance standards, sample composition, level of precision required and more.

Soil Classification: Foundation and Pavement Design Starts Here
Soil Classification: Foundation and Pavement Design Starts Here

There’s more to consider in planning a new highway project than location. This blog post helps lay out the importance of soil classifications, visual inspection and field/laboratory testing, ASTM, AASHTO and state DOT regulations, resources and tools and more.

Sieve Analysis of Coarse Aggregate: Art of Sample Prepping

In part 2 of this three-part series, we’ll outline a sieve analysis of coarse aggregate including proper preparation of bulk field samples for lab testing and necessary equipment and tips.

Wet Sieving: A Practical Guide
Wet Sieving: A Practical Guide

When dry sieving isn’t sufficient for producing an acceptable degree of separation between individual fractions of a sample, it’s time to try wet sieving. This blog post covers the importance of wet sieving, when it is best used, and recommended equipment for various procedures.

Sieve Analysis of Coarse Aggregate: Tips on Sample Collecting
Sieve Analysis of Coarse Aggregate: From the Field to the Lab (Part 1)

In Part 1 of this thee-part series, we’ll cover sieve analysis of coarse aggregate, beginning from gathering samples at a job site, including tips and necessary equipment.
