The core technique for determining the state of concrete is to accurately identify whether the concrete meets the construction requirements (such as pumping, pouring, and vibration) through the detection and evaluation of “flowability cohesiveness water retention”.
The so-called “state” refers to workability (fluidity, cohesiveness, water retention), and the following core techniques are tested through practical experiments, judged by experience, and scientifically verified, suitable for trial and error .
