Ka wehea te ranunga whakaheke wai teitei ki: (1)lignosulfonates; (2) nga tote kakara polycyclic; (3) sulfonates kapia wairewa-wai.Naphthalene superplasticizer, superplasticizer aliphatic, superplasticizer amino, polycarboxylicsuperplasticizer waikawa, etc.

Ko te ahua o te ahua ka wehea ki te wai me te paura.Ko te ahua ahua ka wehea ki te wai me te paura. Ko te tikanga o te wai totoka ko te 20%, ko te 40% (e kiia ana ko te waipiro whaea), 60%, a ko te tikanga o te paura he 98%. E ai ki te wai whakaheke me te whakarei ake i te kaha okaihoko whakaheke wai, ka wehewehea ki nga kaihoko whakaheke wai noa (e mohiotia ana ko te plasticizer, ko te tere whakaheke wai kaore i te iti iho i te 8%, e whakaatuhia ana e te lignosulfonate), te superplasticizer (e mohiotia ana ko te superplasticizer) Plasticizer, ko te reiti whakaheke wai kaore i te iti iho i te 14%, tae atu ki te naphthalene, te melamine, te sulfamate, te aliphatic, me etahi atu) me te mahi nui-whakaiti wai (kaore i te iti iho i te 25% te utu whakaheke wai, me te waikawa polycarboxylic Kei te tohuhia e te kaihoko whakaheke wai), ka wehea ki te kaha wawe. momo, momo paerewa me te retarder.

I muri i te taapiri i te ranunga raima, ka taea te whakamarara i nga matūriki ciment, ka taea te whakapai ake i tana mahi, te whakaiti i te kohi wai o te waeine, me te whakapai ake i te rere o te ranunga raima; whakaitihia ranei te kohi ciment wae me te whakaora sima.
