Description

Technical Field

[0001] The utility model relates to the technical field of concrete shrinkage rate testing, in particular to an environmentally friendly concrete shrinkage rate testing device. Background Art

[0002] Concrete shrinkage refers to the volume reduction that occurs during the initial setting or hardening process of concrete. It is generally categorized as plastic shrinkage (also known as sedimentation), chemical shrinkage (also known as intrinsic shrinkage), drying shrinkage, and carbonation shrinkage. Excessive shrinkage can cause concrete cracking. Existing technology uses instruments to measure concrete shrinkage.

[0003] However, the existing technology lacks the function of quickly evaporating the moisture in concrete. In actual use, when measuring the shrinkage rate of concrete, the moisture in the concrete needs to be evaporated and dried to simulate the impact of concrete shrinkage in a natural environment. The existing technology usually allows the concrete to remain static and wait, lacking the function of quickly evaporating the moisture in the concrete, resulting in limitations in the existing technology. Moreover, the existing technology also lacks the function of rapid demoulding. In actual use, after the concrete solidifies, it is inconvenient for the staff to take out the concrete because it is inside the device, or it is easy to cause cracking and damage to the concrete when taking it out, making it impossible to accurately measure the shrinkage rate of the concrete.
