Joalo ka ha bohle re tseba, polycarboxylate superplasticizer ke motsoako o mocha oa konkreite.

E ka fihla ho 30% ea ho fokotsa metsi ka tekanyo ea 0.2% ho ea ho 0.3%.

Ho fihlella karo-karolelano ea 20% ea metsi, tekanyo ea sodium naphthalene formaldehyde e tla ba hoo e ka bang 0.8% -1%.

Theko e kopaneng ea polycarboxylate superplasticizer 50% e ka ba 1065$ ka tone ka sephutheloana sa tanka ea IBC hona joale, theko e kopaneng ea sodium naphthalene formaldehyde e ka ba 814$ ka tone.

Ka holim'a tsohle, ke nahana hore ke ka lebaka leo bareki ba bangata ba fetohang ho sebelisa polycarboxylate superplasticizer.
