technical field

The invention relates to a fully automatic concrete setting time measuring device and a measuring method.

Background technique

The setting time of concrete is divided into initial setting time and final setting time, which is one of the important indicators of the performance of concrete mixture. The initial setting time refers to the time required for the concrete mortar to lose its plasticity from the time when the concrete is mixed with water; the final setting time is the time required for the concrete mortar to completely lose its plasticity and begin to produce strength after the concrete is mixed with water. The setting time of concrete is of great significance in construction. In order to ensure that the concrete mortar has enough time to be in a plastic state during engineering construction for easy operation and use, the minimum initial setting time of concrete is stipulated in combination with the construction requirements of concrete; in order to make the concrete mortar that has formed the shape of the engineering structure obtain strength as soon as possible, so that Able to bear the load, combined with the construction requirements of concrete, it is stipulated that the final setting time of concrete shall not be later than the specified time. Therefore, the setting time of concrete can be used as the main index reflecting the setting performance of concrete.
