Concrete superplasticizers are among the most widely utilized admixtures in concrete engineering, and they come in various types, also referred to as high-range water reducers or superplasticizers. These additives are employed to enhance the workability of concrete while maintaining its strength.
1.Polycarboxylatetherbaserede (PCE) superplasticizers:
PCE Superplasticizers Are Widely Used In The Construction Industry Due To Their High Water-Reducing Capacity And Excellent Dispersing Properties. They Offer Improved Flowability And Can Reduce The Water Content In Concrete Mixtures Significantly.
It Is Worth Noting That Polycarboxylate Ether-Based (PCE) Superplasticizers Are Divided Into Liquid And Powder, Which Can Have Advantages, Which I Will Focus On In Other Articles. For Details, Please Refer To 《Polycarboxylate Superplasticizer (Powder)》
2.Sulfonated Melamine Formaldehyde (SMF) Superplasticizers:
SMF -superplasticizers bruges ofte i præfabrikerede betonapplikationer. De giver et moderat niveau af vandreduktion og forbedret arbejdsevne.
3.Sulfonated Naphthalene Formaldehyde (SNF) Superplasticizers:
SNF-superplasticizers er blevet brugt i mange år og er kendt for deres effektive vandreducerende egenskaber. De kan øge betonens nedgang, mens de opretholder dens styrke.
4.Protein-Based Superplasticizers:
Disse superplasticizers er afledt af landbrugsbiprodukter såsom sojabønner eller majs. De er mindre almindeligt anvendt sammenlignet med andre typer, men tilbyder god ydelse med hensyn til forbedring af vandreduktion og forbedring af arbejdsevnen.
5.Lignosulfonate-Based Superplasticizers:
Lignosulfonater er biprodukter af træmasseprocessen og kan bruges som superplasticizers. De leverer moderat vandreduktion og har gode spredningsegenskaber.
