Dial Gauge Extensometer, Compressometer Dial Indicator, 6x12in
Compressometer/Extensometers are like the Compressometer in that they measure average deformation and strain of concrete cylinders during compression testing to determine modulus of elasticity. But a third center yoke attaches to the specimen to measure horizontal extension. This allows for determination of modulus of elasticity and Poisson’s ratio. A second mechanical dial or digital indicator between yoke segments measures transverse deformation at the same time. Mechanical dial indicators measure specimen deformation. Models for 4in (102mm) or 6in (152mm) concrete cylinders are available. Yokes are aluminum, other parts are cadmium plated steel.
Features:
-
Third yoke measures horizontal extension
-
Dual mechanical dial indicators or digital indicators
-
Models for 4in (102mm) or 6in (152mm) concrete cylinders
Meets Standards:
ASTM C469/469M
Compressometer and extensometer are two important instruments used in concrete cylinder compressive strength tests. These instruments are used to measure the mechanical properties of concrete specimens so engineers and researchers can evaluate the quality and durability of concrete structures.
A compressometer is a precision instrument used to measure the axial deformation or strain of a concrete cylinder during a compressive strength test. It has two hardened steel plates with dial gauges attached. The compressometer is placed on the concrete specimen and as the load is applied the movement of the plates is measured and gives valuable information on the strain of the concrete.
On the other hand, an extensometer with measures the deformation or strain of the concrete specimen or concrete cylinders perpendicular to the applied load. It has two arms with linear variable differential transformers (LVDTs) attached to the concrete surface. As the load is applied the extensometer measures the change in length or extension of the specimen accurately.
By using compressometers and extensometers on the concrete cylinders together during concrete cylinder compressive strength tests, engineers can get a full understanding of the behavior of concrete under load. These instruments help to determine the stress-strain relationship of the material, elastic modulus, Poisson’s ratio and other mechanical properties.
The data from compressometers and extensometers can be used to evaluate concrete mix designs, monitor concrete structures over time and design new construction projects. It allows engineers to make informed decisions on material selection, reinforcement design and structural safety.
Compressometers and extensometers are key instruments in concrete cylinder compressive strength tests, measure strain and deformation precisely. They help to develop concrete technology and ensure concrete structures are durable and reliable.
