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.
