Continue Reading Brass or Stainless Steel Test Sieves: That Was Then, This Is NowThe 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.
Continue Reading Construction Materials Testing: An OverviewThe dynamic cone penetrometer (DCP) is an efficient tool used to perform soil strength assessments of fine-grained soils, pavement base courses, and more. Learn about the advantages of this tool compared to other penetration testing methods and how to perform penetration tests using the dynamic cone penetrometer.
Continue Reading The Dynamic Cone Penetrometer (DCP): Applications and EquipmentIf you regularly perform asphalt theoretical maximum specific gravity (Rice) tests, the Gilson Rice Shaker is a time-saving tool to have in your lab. Find out why this unit is the key to determining accurate specific gravity determinations for asphalt, aggregates, and soils.
Continue Reading The Gilson Rice Shaker: A Versatile Tool for Specific Gravity TestingUnconfined 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.
Continue Reading Unconfined Compressive Strength of SoilSoil is a natural material and is sometimes employed as a construction material without modification. It is crucial to understand how it performs in its original (in-situ) environment. For this article, we will examine various field tests of soil and the equipment required to perform them.
Continue Reading Soil Field Testing: Physical Properties of SoilSome 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.
