by Materialsanalyticalgroup, posted in Uncategorized

Posted by Matthew Anderson on March 26, 2025 Chloride in concrete can be a silent killer for steel reinforcement—triggering corrosion that cuts a structure’s life short. If you’re a contractor pouring slabs, a manufacturer supplying precast, or an engineer signing off on specs, knowing how to test for chloride is a game-changer. The good news? … Continue reading Step-by-Step Guide: Testing Chloride in Concrete with Silver Nitrate Titration

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

by Materialsanalyticalgroup, 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 Materialsanalyticalgroup, 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
