Superplasticizers Flashcards
1
Q
What are superplasticizers used for?
A
To increase workability and compressive strength without adding more water, which will result in porosity
2
Q
What are superplasticizers?
A
High MW polymers
3
Q
How do superplasticizers work?
A
> adsorbed onto cement particle surfaces, breaking down agglomerates and making cement particles repel through steric hindrance
reduce friction between particles and liberate water that would’ve been trapped in agglomerates
