Micro-Measurements has developed a line of gage (gauge) sizes expressly intended for use on concrete structures. These include 1" (~25mm), 2" (~50mm) and 4" (~100mm) gage lengths, suitable for making reliable average measurements on virtually any concrete material.

Strain Gage Sensors and Concrete – The Hard Facts ASTM

(American Society for Testing and Materials) Committee C09 focuses on developing standard test methods and guidelines for concrete and other aggregate type materials. Concrete materials present unique challenges for strain measurement, because the aggregate can skew results depending on the size strain gage sensor used. 

 

Micro-Measurements also offers a strain sensor specifically intended to be embedded in concrete castings for long-term monitoring. The EGP-5-350 is a rugged device, capable of withstanding the trauma of having tons of concrete poured around it, and still providing years of precision strain measurement. ASTM C39 (Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens) describes procedures for measuring the compressive strength of concrete specimens.
