I enei wa, ka timata te maha o nga ota ki te whakaputa.Ka kaweake e matou ki nga whenua ke, ka tuku mai i nga tipu raima rite Hainamana, te tipu puranga me etahi atu.

Inaianei kei te whakawhanake to maatau tohunga hangarau i tetahi superplasticizer polycarboxylate matawhānui.Ko ona painga ko nga kaihoko e whakamahi ana i te superplasticizer polycarboxylate hei kaihoko whakaheke wai he pai ake, he ohanga, he pai ake.Ko nga rauemi matawhānui polycarboxylate superplasticizer matua, he rite te tae ki te momo whakaheke wai (CL-WR-50) me te momo pupuri whakaheke (CL-SR-50).Mo nga kaihoko i te tuatahi ka whakamahi, kaore te nuinga o ratou e mohio ki te whakamahi wehe, ahakoa ka whakaratohia e matou he tautoko hangarau, kaore e taea e etahi o nga kaihoko te mahi i te ahua raima pai rawa atu.Ka taea e ratou te whakamahi i te superplasticizer polycarboxylate matawhānui.

Ina tata nei, kei te piki haere nga utu o te polycarboxylate superplasticizer TPEG me HPEG ia ra i Haina.Na te poto o te rokiroki me te maakete kaore e taea te whakatutuki i nga whakaritenga, ko te utu he nui atu i te Hune.Mena ka whakatau nga kaihoko ki te hoko polycarboxylate superplasticizer mai i Haina, me tere.Ka piki tonu te utu e whai ake nei.He kaha te tari tiaki taiao ki nga ahumahi matū.I te wa poto, ka kore e heke te utu.Nga korero, ka taea e koe te whakapiri mai ki a maatau.Ko te tauira kore utu he whakarato mo to whakamatautau.
