Ngā rauemi hiato pūmua whakakaha muka karāhe (GFRP)he paerewa ēnei mō te hanganga nā te mea he teitei te ōwehenga kaha-ki-taumaha, kāore e waikura, ā, he maha ngā whakamahinga mō te tukatuka.

Hei tīmatanga, ka whakamahia whānuitia te GFRP i roto i ngā hanganga tūturu hei hanga i ngā huānga tautoko kawenga matua pēnei i ngā kurupae me ngā pou, me ngā panera papa. Mā te whakamahinga o ngā tauira muka karāhe maha-tuaka me ngā kapia ātete-huarere ka taea e ngā wāhanga GFRP te whakaputa i te kaha kume me te piko tino pai. Hei tauira, ka taea e ngā kurupae kua whakapakaritia ki te GFRP te whakaiti i ngā āhuatanga whakawhiti-wāhanga me te pupuri tonu i te kaha kawenga hanganga, ā, ka nui ake te wāhi o roto e taea te whakamahi. I roto i ngā hanganga papa, ka taea e ngā āhuatanga piko pai o ngā rau GFRP te whakapai ake i te pakari hanganga, te whakaiti i te piko waenga-whānui, me te whakaroa i te roa o te ratonga.

Tuarua, i roto i te umanga hanga, kei te whakakapi haere te GFRP i te whakakaha maitai tuku iho hei whakapai ake i te pakari o te hanganga me te ātete ki te waikura. Ka waikura ngāwari te whakakaha maitai tuku iho i roto i ngā taiao makuku, rehu tote, matū rānei, engari he tino pai te ātete ki te waikura o te GFRP. E whakaatu ana ngā whakamātautau ahakoa i roto i ngā taiao tote nui,GFRPe mau tonu ana i te neke atu i te 90% o tōna kaha i muri i te 1000 hāora o te whakamātautau waikura tere. Nā tēnei ka waiho te GFRP hei rauemi hanganga tino nui i roto i ngā piriti takutai, ngā tauranga, me ngā whare ahumahi. Hei tāpiri, he tata te tauwehenga whānui wera o te GFRP ki tērā o te raima, e ārai ana i te kukū o te ahotea nā ngā huringa pāmahana, ā, e whakaroa ana i te roanga o te ora o ngā hanganga raima.

E whakamahia whānuitia ana hoki ngā wāhanga GFRP i roto i ngā taiao tino waikura, pērā i ngā turanga o ngā tāke i roto i ngā tipu matū, ngā turanga o ngā papaaho moana, me ngā pakitara o ngā puna kaukau i roto i ngā tipu waipara. Ka pāngia ēnei wāhi e ngā taumata tiketike o ngā waikawa, ngā turanga, me ētahi atu matū waikura mō te wā roa. Ahakoa he ngāwari te waikura o ngā rauemi tuku iho, he tata kore te GFRP e pāngia e te whakaekenga matū. E whakaatu ana ngā tatauranga i muri i te 6-marama o te pānga ki te otinga waikawa, me te pH o te 3, ka 95% te kaha piko taketake o te GFRP, nō reira ka whakaratohia he whakamana mō te wā roa ki ngā hanganga i roto i ngā taiao kino me te iti o ngā utu tiaki me te whakakapinga. Me whakatika me te whakakaha hoki ngā hanganga tawhito, pērā i te maha o ngā piriti rori me ngā whare whenua. He rauemi whakakaha tino pai te GFRP nā te mea he kaha, he māmā, ā, he pai te piri ki te raima. I roto i ngā kaupapa whakakaha piriti, ko te wāhanga kume o ngā kurupae ka whakapirihia ki ngā pepa GFRP hei whakakaha i a rātou i te piko. Ka taea te whakakaha i ngā kurupae raima whakakaha GFRP tae atu ki te 20-50%. I roto i ngā whakatikatika kauhanga, ka whakamahia ngā hua mata GFRP ki te whakakaha whakapuru hei whakakaha i te toka e karapoti ana, kia pumau ake ai, kia ātete ai hoki ki te kutikuti. He tere te tāutanga o te arai GFRP, ā, kāore e tino whakararuraru i te hanganga o nāianei, nō reira he pai mō ngā whakatikatika ohorere o ngā whare tawhito me ngā piriti.

Hei whakamutunga, i roto i te hangarau piriti me te kauhanga, mō ngā piriti tawhito, ka hipokina te mata o ngā wāhanga e amo ana i te kawenga kiNgā rau, ngā pereti rānei o te GFRP, mā te whakamahi i te kapia epoxy motuhake mō te hononga kaha, ka taea te whakapai ake i te kaha ki te kawe kawenga me te whakaroa i te tukanga koroheketanga o te hanganga. I roto i te hangarau kauhanga, ka mahi tahi ngā whatunga GFRP me te raima hei hanga i tētahi hanganga tautoko whakauru, ka whakarei ake i te ātete kutikuti o te kauhanga me te pumau mō te wā roa, inā koa i roto i ngā wāhi e ngāwari ana ki te rū whenua.
