Description

Concrete pressure testing device

Technical Field

The invention belongs to the technical field of concrete pressure testing, and particularly relates to a concrete pressure testing device.

Background

Concrete is a general term for engineering composite materials in which aggregate is cemented into a whole by a cementing material. The term concrete generally refers to cement as a cementing material and sand and stone as aggregate; the cement concrete, also called ordinary concrete, is widely used in civil engineering. The concrete press is a press and is mainly used for testing the compressive strength of building material test blocks such as concrete and the like.
