Performance changes and influencing factors of concrete in the hardening process
The setting and hardening of concrete has to go through the three processes of initial setting, final setting and initial strength, which is mainly realized by the hydration of cement. The hydration reaction of cement releases heat, which causes the concrete to heat up, and there will be initial volume changes and possible cracks. Understanding the nature of concrete at this stage is of great benefit to controlling the construction quality of concrete.

Analysis on the method of testing the water consumption of cement to reach the standard consistency
Cement standard consistency water consumption refers to the ratio of water consumption to cement quality when the cement paste reaches the standard consistency. The water consumption standard for the stability test can be obtained by testing the water demand for the cement paste to reach the standard consistency. The method for measuring water consumption of cement standard consistency is introduced below.
