Did you know? Every lab has a designated ‘problem child’ piece of equipment that only works when the senior tech is watching, or if you threaten it with the manual. https://hubs.ly/Q02_XG5G0

Did you know? Materials testing labs often use liquid nitrogen at -196°C to freeze and preserve samples quickly. https://hubs.ly/Q02_XLy90

Failure Analysis is one of the scientific investigative services that clients rely on RJ Lee Group to find answers. This month we continue our look at types of failure with Alkali-silica reaction (ASR), a common cause of premature concrete deterioration that results in expansion and cracking of concrete elements. ASR is a chemical reaction between concrete and silica-bearing minerals present in some aggregates. Learn more about this type of failure in our blog "What is Alkali-Silica Reaction. #failureanalysis #ASR #concrete https://hubs.ly/Q02_XPCs0

Did you know? Fourier-transform infrared (FTIR) spectroscopy is widely used in chemical characterization to identify unknown substances by analyzing their unique molecular vibrations and bonds. https://hubs.ly/Q02_XzcP0

Did you know? By analyzing air voids in concrete, petrographers can determine if a mix was properly air-entrained, which is critical for freeze-thaw resistance. https://hubs.ly/Q02Py6ZM0
