What is a concrete pressure testing machine?
In the field of construction engineering and materials science, the concrete compression testing machine is a key testing equipment used to determine the compressive strength of construction materials such as concrete, cement, and bricks. With the recent emphasis on quality control in the construction industry, this equipment has once again become a hot topic. This article will combine the hot content of the entire network in the past 10 days to introduce in detail the definition, use, classification and technical parameters of concrete pressure testing machines, and attach structured data for reference.
1. Definition and use of concrete pressure testing machine
A concrete pressure testing machine is an instrument that measures the compressive strength of a material by applying pressure to a specimen through a hydraulic or electronic system until it fails. It is widely used in engineering quality inspection, laboratory research and construction material production links to ensure that materials comply with national standards (such as GB/T 50081-2019).
