Ngā mīhini whakaranu raima muka mahi tino-teitei (UHPFRC) | CoNele

He mīhini motuhake ngā mīhini whakaranu raima muka mahi-tino teitei (UHPFRC) i hangaia hei whakatutuki i ngā whakaritenga ahurei o te whakaranu i te UHPFRC, he rauemi hiato kaha-teitei kei roto ngā muka maitai, ngā muka hangai rānei. Mā ēnei mīhini whakaranu ka whakarite kia rite te horapa o ngā muka, ā, ka tutuki te matotoru e tika ana mō ngā āhuatanga miihini pai rawa atu o te UHPFRC (hei tauira, te kaha pēhi >150 MPa, te kaha kume >7 MPa). Kei raro nei he tirohanga whānui taipitopito i runga i ngā whakatakotoranga hangarau, ngā āhuatanga matua, me ngā tono ahumahi:

1. Ngā momo whakaranu UHPFRC
Ko ngā mīhini whakaranu e whakamahia whānuitia ana mō te UHPFRC ko ngā mīhini whakaranu aorangi me ngā mīhini whakaranu aorangi poutū, e whakakotahi ana i ngā kaha kutikuti teitei me te whakahaere ngāwari i ngā rauemi hei ārai i te poipoi muka.
Ngā Whakaranu Aorangi (raupapa CMP nā CoNele): Kei roto i ēnei ngā whetū whakaranu hurihuri e hanga ana i te nekehanga whakahē-au, kia tere ake ai te whakaranu (15-20% tere atu i ngā whakaranu tuku iho).
Ko ngā tauira pēnei i te CMP500 he 500L te kaha tukunga, he 18.5kW te mana whakaranu, ā, he pūnaha tukunga waipēhi hoki.
2. Ngā Āhuatanga Hangarau Matua o ngā Ranu Aorangi UHPFRC
Tuku Taipana Teitei: Mā ngā pouaka whakaiti ahumahi me te taipana putanga teitei ka whakarite kia maeneene te whakaranu o te anga matotoru o te UHPFRC. Ka whakaratohia e ngā hononga waipēhi te tiaki i te taumaha me te ārai taipana.
3. Ngā Kaihanga me ngā Tauira
Ko ngā kaihanga matua o CoNele e tuku ana i ngā mīhini whakaranu UHPFRC motuhake me ngā tiwhikete CE/ISO:
Mīhini Co-Nele: Ka whakamahia e ngā mīhini whakaranu UHPFRC te hangarau Tiamana mō te ōritetanga me te pakari, e tautokona ana e te 20+ tau o te wheako ahumahi.
4. Ngā horopaki tono
He mea nui ngā mīhini whakaranu UHPFRC mō:
Te Hanga Piriti: Hei hanga i ngā papa piriti angiangi, pakari, me ngā arai waikeri rino kōpikopiko. Hei tauira, ko te hangarau UHPFRC rehu a Freyssinet e whakamahi ana i ngā mīhini whakaranu ritenga hei whakatutuki i ngā arai matotoru 6cm me te pakari 100-tau.
Papa Ahumahi: Nā te ātete nui ki te pakū, he pai te UHPFRC mō ngā whare putunga me ngā whare hanga.
Whakahoutanga Hanganga: Nā te kaha o te here o te UHPFRC ka taea te whakatika i ngā hanganga raima kua pakaru, pērā i ngā pou me ngā pereti, me te iti rawa o te matotoru.
