For decades, rotary sifters have served as a reliable and efficient unit for particle sizing operations. Learn about the different types of rotary sifters available and how Gilson's design philosophy helped shape more advanced units that suppress noise and dust.
Knowing how to properly test and verify asphalt binders is essential to understanding how asphalt will react to various climate conditions. This guide covers the methods used to classify asphalt binders and how to perform these tests to ensure optimal pavement performance and longevity.
For this blog article, we will look at the use of brass for weaving the mesh of laboratory test sieves and how stainless steel has become a more efficient and cost-effective mesh material.
The term construction materials testing sounds like a catch-all term for analyzing everything from nails to doorknobs. However, for the civil engineering industry, it has come to mean the characterization of a handful of things by using specific test methods in a construction materials testing laboratory: concrete, aggregates, asphalt, and soils. This blog will take a high-altitude view of what construction materials are, the most important properties to test for, and the right equipment to get the job done.
Verification, calibration, and performance tests all contribute to the accuracy of test sieves. Understanding sieve accuracy will ensure you get the information you need out of your test sieves or screen trays.
Test methods for dry granular materials must be built around the flowability of the material. No sampling, sizing, or handling method can be performed accurately or efficiently if it does not work in harmony with the material's flow properties.
Unconfined compressive strength is a standard geotechnical test performed on cohesive soil samples in construction materials testing laboratories. Straightforward sample preparation and a rapid, uncomplicated procedure makes unconfined compression tests cost-effective when fundamental strength values are adequate for design.
Every stage of sampling, dividing, and testing granular material is affected by its flow properties. Understanding a particular material and the unique factors that impact its flowability increases the efficiency and accuracy of your laboratory testing and can even help control your budget. In this article, we discuss what equipment is best suited for your testing application.
Although Alkali-Silica Reactivity (ASR) has created problems in concrete mixtures for centuries, the mechanism was not understood and documented until the mid-1930s. ASR is now recognized as a significant cause of concrete deterioration anywhere in the world where siliceous aggregates are found. In this blog article, we discuss what ASR is, the effect it has on concrete, prevention, and the equipment to use for testing.
Some test methods must be performed on the spot to ensure that the best products are being produced or placed following specified procedures. Portable weighing devices are especially important to operate accurately and conveniently in remote locations. In this blog post, we’ll discuss what to look for when choosing one.
