Is My Water Corrosive? Is My Water Scale Forming? How Langelier Saturation Index Measures How Aggressive or Scale Forming Water Is

by magroupllc, posted in Building Materials, Corrosion, Forensic Chemistry, Metals, Microscopy, SEM, water

Langelier Saturation Index (LSI) is a calculation that uses the data of multiple analyses to estimate how corrosive or scale-forming a water is. The chemistry of the water is analyzed, as well as the environmental conditions determined, to evaluate how likely the water would be to corrode or form a scale in pipes. LSI is … Continue reading Is My Water Corrosive? Is My Water Scale Forming? How Langelier Saturation Index Measures How Aggressive or Scale Forming Water Is

Carbonation of Conrete Eliminates Corrosion Passivation Effect of Cement Paste

by magroupllc, posted in Building Materials, Carbonation, chloride, Concrete, Corrosion, Expansion, Forensic Chemistry, Metals

Concrete and steel together form the backbone of every bridge, building, and road in a symbiotic relationship. The steel gives the concrete higher durability by increasing tensile strength, and the concrete provides physical and chemical barriers for the steel, protecting it from the elements. With exposure to air and water, the chemical properties of the … Continue reading Carbonation of Conrete Eliminates Corrosion Passivation Effect of Cement Paste

Handheld XRF Analysis for Identification of Stains, Lead Paint, Zinc Primer, Galvanizing, and Aluminum Substrate

by magroupllc, posted in Coatings, Corrosion, Forensic Chemistry, Handheld XRF, Metals, Microscopy, staining

Handheld XRF (x-ray fluorescence) is a powerful, non-destructive technique that can identify and quantify multiple elements simultaneously. The instrument has a wide range of applications including metal identification, determination of the presence of lead, soil analysis, coating analysis, and stain analysis. XRF works by emitting an x-ray beam capable of displacing electrons in the inner … Continue reading Handheld XRF Analysis for Identification of Stains, Lead Paint, Zinc Primer, Galvanizing, and Aluminum Substrate

How the pH of Concrete is Related to Corrosion Protection

by magroupllc, posted in Carbonation, chloride, Concrete, Corrosion, Forensic Chemistry

In concrete, steel is often embedded to reinforce the concrete, providing tensile and flexural strength. This combination of steel and concrete allows for some of the most durable and beautiful structures to be built. Concrete, as a building material, has superior compressive strength to most materials, and is durable in many different exposure environments. However, … Continue reading How the pH of Concrete is Related to Corrosion Protection
