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.
Moisture/LOI Determination in Cement, Fly ash, Gypsum, and Lime using Thermogravimetric Analysis Techniques
Thermogravimetric analysis (TGA) is a commonly used method for Moisture or Loss on Ignition (LOI) determination in different materials. This webinar will explore enhancements in the method to characterize mass loss in specified materials using LECO TGA instruments.
The methods outlined include Split Loss in Cement, LOI in Flue Gas Desulfurization Solids following ASTM D8339, LOI in Combustion Residues following ASTM D7348, and moisture and LOI in Hydrated Lime.
This webinar is presented by Jeffery Gast, a lead analytical chemist.
Carbon and Nitrogen Determination in Adhesives, Laminates, and Cement Fiber Board using the LECO CN928 and the LECO C832
Determining the carbon and nitrogen values in construction materials is crucial for preserving the quality and durability of these products.
In this webinar, the focus is on this application utilizing both the LECO CN928 and the C832. Data from a wide range of materials used in the construction industry will be highlighted.
This webinar is presented by Fred Schultz, an applications chemist.
Cement Clinker Preparation and Microscopic Examination
Cement Clinkers are an intermediate product in the manufacture of Portland Cement, one of the most important components required for concrete manufacturing.
Microscopic examination and analysis of Clinkers is a Quality Assurance process that evaluates the nature and quality of Clinker constituents.
In this webinar, LECO discusses sample preparation, microscopic examination, and the evaluation of Cement Clinkers.
This webinar is presented by Steve Reilly, Corporate Metallurgist.
