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.
