Detection of residual flocculants in washed fine aggregates and exploration of their impact on concrete

During construction, it was found that sometimes the following situations occurred: the slump of the concrete discharged from the machine met the requirements, but within less than 20 minutes, the concrete no longer had fluidity.

Precast Round Ferrule

Upon verification, it was found that no parameter changes had occurred, resulting in the scrapping of the concrete in this vehicle or several consecutive vehicles.

This not only increases the loss of construction raw materials, but also leads to an increase in construction costs and poses significant potential risks to project quality.
