As all know, polycarboxylate superplasticizer is new generation concrete admixture.
It can reach 30% water-reducing ratio with dosage 0.2% to 0.3%.
To reach 20% water-reducing ratio, dosage for sodium naphthalene formaldehyde will be around 0.8%-1%.
Unite price for polycarboxylate superplasticizer 50% is around 1065$ per ton with IBC tank package now, unite price for sodium naphthalene formaldehyde is around 814$ per ton.
Above all, think that’s why more and more customers change to use polycarboxylate superplasticizers.
Recently Stanley rebuilt our factory, expanded the production schedule.our technical department researched new products, like early strength type polycarboxylate superplasticizer used for ready mix concrete plant. from the delivery and package saving aspect, SANSEI developed 55%, 60% solid content and powder type polycarboxylate superplasticizer.
About usage, when people concrete material is good, people can only use our high water reducing type polycarboxylate superplasticizer. If people cement contains mud, need mix-use our high slump retention type and high water reducing type polycarboxylate superplasticizer.
When cement mud content high, the water-reducing ratio for the high slump retention type is higher than water reducing type.
Usually, the mixing ratio for water reducer and slump retainer can be 8:2 or 6:4 or 7:3, when people got our sample for polycarboxylate superplasticizer, need test by people to find suitable ratio with people concrete material.
