Cement is the basis of virtually all of the entire world’s infrastructure. Its value can be attributed to its durability, strength, versatility, and ease of use. For all of the advantages cement offers, it is an unusually complex mixture of carefully balanced ingredients such as lime, silica, alumina, and more.
The quality and strength of cement and other building materials are determined by their chemical makeup. In the following webinars, LECO’s experts explain how chemical and moisture analyses of cement and other building materials can be carried out quickly, efficiently, and accurately.
Total Sulfur and Carbon Determination in Cement and Raw Materials Utilizing the LECO SC832 Series of Instrumentation
This webinar outlines how the LECO SC832 can be used to determine levels of sulfur and carbon across a wide range of construction materials. Sample types presented in this webinar include cement, fly ash, and ore materials.
In addition, the basic operating principles and software features that can be used to simplify the analysis and reporting of results will be covered.
This webinar is presented by Lloyd Allen, Ph.D., Director of the Technical Services Laboratory.
