Background
The setting time of the cement is divided into initial setting and final setting. At a standard consistency water usage, the time required from the addition of water until the slurry begins to lose plasticity and reduce fluidity is called the initial set time. The time required from the time of addition of water until the slurry completely loses plasticity and begins to have a certain structural strength is called the final set time. The setting time of the cementing material is one of important physical indexes of the material, can directly influence the construction progress and the service performance, and is very important for the application of the cementing material in highway engineering or other fields.
At present, the setting time of cement type cementing materials is mainly measured by referring to national standard GB/T1346-2011 or line standard JTG 3420-2020, and the setting time of cement is generally measured by adopting a standard method Vicat instrument method. The test is manually operated, is operated once every five minutes or fifteen minutes, and the initial setting time and the final setting time are judged by observing the sinking depth of a test needle from a free falling body on the surface of the cement paste.
The existing setting time measuring instrument is convenient for recording the setting time of the cementing material, but the existing setting time measuring instrument is not high in stability in the actual using process. When being used for measuring the standard consistency, the measuring needle is very easy to sink into the bottom to impact the glass plate to cause the damage of the glass plate, the diameter of the measuring needle during the initial setting time is thin and is only 1.13mm, the measuring needle is very easy to directly sink into the bottom of the test piece to impact the glass plate due to the low consistency of the slurry during the measuring process of the gelled material, so that the measuring needle is bent or deformed, the measuring data of the measuring instrument is further deviated, the accuracy is lowered, and therefore the standard consistency and the setting time measuring instrument for the gelled material is provided to solve the problem.
