There are so many concrete admixtures, such as retarder and reducing agent, what are their functions?
1. The working principle of concrete water-reducing agent: Water-reducing agent is usually a surfactant, which is an anionic surfactant. It is adsorbed on the surface of cement particles so that the p…
The effect of auxiliary raw materials on the adaptability of admixtures
Fundamental reasons: ① After on-site experiments, the key factor affecting the properties of polycarboxylate superplasticizer concrete in the stone is the mud content of the stone. As the mud content …
The difference between the use of retarder and other admixtures
(1) Characteristics Retarder and retarding superplasticizer have different retarding effects on the slurry and concrete surface. The retardation effect increases with the increase in dosage. Over-admi…
