Compressometer, Mechanical Dial Indicator, 4x8in
Compressometers measure average deformation and strain of concrete cylinders during compression testing to determine the modulus of elasticity. The units consist of two lightweight aluminum alloy yokes which mount around the specimen. The bottom yoke is rigid, while the upper one is hinged to permit pivoting. A fixed rod connects the yokes. Rods and other parts are cadmium-plated steel. A mechanical dial gauge measures specimen deformation. Models with the “D” suffix have a digital indicator. Indicators have 0.2in (5.08mm) range and 0.0001in (.0025mm) divisions. Models for 4in (102mm) or 6in (152mm) concrete cylinders.
Features:
- Lightweight aluminum yokes
- Mechanical dial or digital indicator
- Models fit either 4in (102mm) or 6in (152mm) concrete cylinders
- Meet requirements of ASTM C469/469M

Compressometer and extensometer are two essential instruments used in concrete cylinder compressive strength tests. These devices play a crucial role in accurately measuring the mechanical properties of concrete specimens, allowing engineers and researchers to assess 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 consists of two hardened steel plates with attached dial gauges. The compressometer is carefully positioned on the concrete specimen, and as the load is applied, the movement of the plates is measured, providing valuable data on the strain experienced by the concrete.
On the other hand, an extensometer is used to measure the deformation or strain of the concrete specimen perpendicular to the applied load. It typically consists of two arms equipped with linear variable differential transformers (LVDTs) that are 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 simultaneously during concrete cylinder compressive strength tests, engineers can obtain a comprehensive understanding of the behavior of concrete under load. These instruments help in determining the stress-strain relationship of the material, elastic modulus, Poisson's ratio, and other important mechanical properties.
The data collected from compressometers and extensometers can be used to evaluate the quality of concrete mixtures, monitor the performance of concrete structures over time, and guide the design of new construction projects. It enables engineers to make informed decisions regarding material selection, reinforcement design, and structural safety.
In conclusion, compressometers and extensometers are vital tools in concrete cylinder compressive strength tests, providing precise measurements of strain and deformation. Their usage contributes to the advancement of concrete technology and ensures the durability and reliability of concrete structures.
