3. Kaiwhakahohe kawakore: Ko nga rauemi cimentitious composite Gypsum ka tutuki to ratou kaha tino maroke i raro i nga tikanga kawakore. Ka taea te whakamahi i te raima tere me te 32.5 ciment ki te whakatika i te pH ki te hanga i tetahi taiao kawakore mo te wai.

4. Tautuhinga whakatere: Ko te wa whakarite he tohu mahi matua o nga rawa-whaiaro. Ko te whakarite i te waa he poto rawa, he roa rawa ranei ka kino ki te hanga. Ko te coagulant e whakaihiihi ana i te mahi o te gypsum, te tere ake i te whakatioatanga supersaturated o te gypsum dihydrate, te whakapoto i te wa whakatuu, me te pupuri i te waa whakatuu me te wa whakapakeke o nga rawa-whaiaro i roto i te awhe whaitake.

5. Water Reducer: Ki te whakapai ake i te kiato me te kaha o te rauemi whaiaro-taumata, me whakaiti te ōwehenga wai-ki-sima. Ahakoa e mau tonu ana te rere o te wai, he mea tika te taapiri i te whakaheke wai. Ko te tikanga whakaheke-wai o te whakaheke wai-naphthalene ko nga roopu waikawa sulfonic i roto i te naphthalene-whakaiti wai whakangao ngota ngota hauwai-hononga ki nga ngota ngota wai, ka hanga he kiriata wai pumau ki runga i te mata o te rauemi cimentitious. Ma tenei ka awhina i te paheketanga o nga matūriki rauemi, ka whakaiti i te nui o te whakaranu wai e hiahiatia ana me te whakapai ake i te hanganga o te mea whakapakeke.

6. Te Kaipupuri Wai: Ka whakamahia nga rauemi whakataurite-whaiaro ki runga i te paparanga turanga ahua angiangi, na te mea ka ngawari te uru ki te paparanga turanga. Ka taea e tenei te kore e tika te whakamakuku, te kapiti o te mata, me te heke o te kaha. I tenei whakamatautau, i tohua te methylcellulose (MC) hei kaihoko pupuri wai. Ko te MC e whakaatu ana i te makuku pai, te pupuri wai, me nga taonga hanga kiriata, te aukati i te whakahekenga o te wai me te whakarite kia whakamakuku katoa nga rawa-whaiaro.

7. Te paura polymer redispersible (e kiia ana i muri nei ko te paura polymer): Ka taea e te paura polymer te whakanui ake i te waahanga elastic o te rauemi whakataurite-whaiaro, te whakapai ake i te aukati kapiti, te kaha here, me te aukati wai.

8. Kaihoko whakaheke: Ka taea e nga kaihoko whakaheke te whakapai ake i nga ahuatanga o te mata o te papanga-whaiaro, te whakaiti i nga mirumiru i te wa e hangai ana, me te whai waahi ki te kaha o te rauemi.
