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.
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.
The Gray Pages: the how and why of test methods and a guide to performing concrete and aggregate tests efficiently while complying with requirements within the standards.
In part 3 of this three-part series, we’ll cover the procedure for effective particle size distribution of coarse aggregates, useful equipment and testing tips.
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.
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.
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.
The Concrete Test Hammer is a critical part of your tool kit when assessing potential problems in concrete structures, but it can also create problems if expected to perform beyond its capabilities. This blog post outlines the proper way to use this tool for establishing strength estimates and relationships by comparison.
A method to simulate long-term, oxidative aged asphalt binder is important for predicting distress in asphalt as it ages. A Pressure Aging Vessel is a great solution and this blog post will highlight the background and benefits of these powerful machines.
Abrasion testing is an important component to your quality control process. This follow-up post presents the benefits of the widely-used L.A. Abrasion Test.
