How to Identify the Source of a Water Leak in a Commercial Building

by magroupllc, posted in Building Materials, chloride, Concrete, Corrosion, Forensic Chemistry, staining, sulfate, water

Unwanted water in buildings can cause staining, degradation of building materials, and an environment for mold to grow. Water can come from a few possible sources in a building, including drinking water, sewer plumbing, a leak starting at the exterior of the building envelope, ground water, and a pool if the building has one. The … Continue reading How to Identify the Source of a Water Leak in a Commercial Building

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

Basic Coating Failure Analysis

by magroupllc, posted in Coatings, Uncategorized

Coatings are used on buildings and structures to protect the components of each from weather, and any conditions the components will be exposed to. A properly applied coating can last for years, but a coating that has improperly applied can fail quickly. Most coating failures are caused by insufficient surface preparation, which lead to a … Continue reading Basic Coating Failure Analysis

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
