What is a concrete elastic modulus testing machine?
In the fields of construction engineering and materials science, the concrete elastic modulus testing machine is an important testing equipment used to determine the elastic modulus of concrete. The elastic modulus is the ratio of stress to strain within the material during the elastic deformation stage, and is an important indicator of the material's ability to resist elastic deformation. This article will introduce in detail the definition, working principle, application scenarios and related data of the concrete elastic modulus testing machine.
1. Definition of concrete elastic modulus testing machine

The concrete elastic modulus testing machine is a device specially used to test the elastic modulus of concrete. It calculates the elastic modulus value by applying a certain load and measuring the deformation of the concrete specimen. This equipment is widely used in construction engineering, bridge engineering, tunnel engineering and other fields to provide a scientific basis for quality control of concrete materials.
2. Working principle of concrete elastic modulus testing machine
The working principle of the concrete elastic modulus testing machine is based on Hooke's law, that is, within the elastic limit, the stress and strain of the material are proportional. The testing machine completes the test through the following steps:
1.Specimen preparation: A concrete specimen (usually a cylinder or prism) is placed on the loading platform of the testing machine.
2.Load: Apply axial pressure to the test piece through a hydraulic or mechanical system, and record the load value.
3.Deformation measurement: Use a displacement sensor or strain gauge to measure the deformation of the specimen.
4.Calculate: Calculate the elastic modulus based on load and deformation data.
