A certain project said, “The slump of freshly mixed concrete was lost in 10 minutes, causing dozens of cubic meters of concrete to be unable to be constructed.
Your admixture manufacturer should come and adjust it quickly, and you will be responsible for the economic losses caused!” After the accident, we immediately set off and arrived at the site to replace the raw materials of the concrete one by one using the elimination method, observe the working performance of the concrete, and ultimately lock the cause on the washed sand.
