Building Strong Foundations

Cement forms the basis of virtually the entire world’s infrastructure. Its value lies in its versatility, strength, durability, and ease of use. For all of its benefits, it is a surprisingly complex mixture of a balance of ingredients such as lime, silica, alumina and more. The quality and strength of cement and other building materials is determined from their chemical make-ups. Learn from LECO’s experts as they explain how chemical and moisture analyses of cement and other building materials can be performed quickly, efficiently, and accurately in this series of webinars.

Total Sulfur and Carbon Determination in Cement and Raw Materials Utilizing the LECO SC832 Series of Instrumentation

This webinar will review the application of the LECO SC832 family for the determination of sulfur and carbon in a wide variety of construction materials.  Sample types covered in this presentation include cement, fly ash and ore materials. In addition, the basic operating principles will be covered as well as software features that can be used to simplify the analysis and reporting of results.  |  Presented by Lloyd Allen, Ph.D., Director Technical Services Laboratory

Moisture/LOI Determination in Cement, Fly ash, Gypsum and Lime using Thermogravimetric Analysis Techniques

Thermogravimetric analysis (TGA) is a widely used technique for Moisture or Loss on Ignition (LOI) determination in various materials. This webinar will explore enhancements in the method technique to characterize mass loss in specified materials using LECO TGA instruments. The methods discussed will include Split Loss in Cement, LOI in Combustion Residues following ASTM D7348, LOI in Flue Gas Desulfurization Solids following ASTM D8339 and Moisture and LOI in Hydrated Lime. | Presented by Jeffery Gast, Lead Analytical Chemist
