Show raw source

Superplasticizers make normal or low [[slump]] [[concrete]] to a high [[slump]] concrete. The resulting high slump concrete often requires no vibration to pour into the form. Higher slump concrete can withstand free fall distances, and are more resilient to [[ConcreteSegregation segregation]] when mixed with superplasticizers. They are categorized into Types F and G [[ConcreteAdmixtures admixtures]], and generally last only 30 min to 1 hr. Type G can generally be re-dosed to increase plasticity.
