Ka nui o ka pahu

'O ka Pōhaku he mea hana i kūkulu'ia ma ke kāko'o'ana a me ka ho'oikaika hou'ana o kahi hui'ana i koho'ia a me ka ho'opili'ia. 'O ka'ene'ena ia a me nā mea'ē a'e'ē a'e,'o nā mea li'ili'i a me nā'āpana nui me ka ho'ohui'ana o ka wai. I kekahi mau kumu, kahi e pono ai ka mākaukau kūikawā o ke koi, no ka mea, i loko o ka'enehana hana ka'a'ūponi,'a'ole hiki ke ho'ohui'ia ka wai, akā, ho'ohana'ia nā mea ho'ohui kūikawā.

'O nā mea nui o ka launa'ana o ka nohona, me ka loa'a'ana o kahi kumu waiwai nui. Hiki ke ho'ohana'ia ia ma nā'ano hana. Hiki ke kapa ia he mea ākea, kahi i ho'ohana ikaika'ia ma nā wahi āpau a me nā papa hana. He kino ia me ke ahi wela, ho'omelemo'ole a'a'ohe mālama i ka ho'okalakili'iliahi.

'O ka ho'oku'u'ana i ke one, ka lepo, ka wai a me ka palapala e hiki ai iā'oe ke loa'a ka mākau e koi'ia ana o ka sima. Ka lākiō, e hilinaʻi ma ka ona mau maʻiʻo o ke one a me ka iliili, lepo pipili no hoi ka papa a me ka hapa. I kekahi mau kumu, e pili ana i ka nui a me ka ho'ohui'ana o nā mea ho'opihapiha: nā mea wai wai, nā mea plastifers, a me nā mea'ē a'e. He la'ana, no ka loa'a'ana o ka māmā o ka M200 mīkini, e ho'ohana i ka ciment 400.

'O kekahi o nā'ano nui o kēia'enehana,'o ia ka lāpili wai. Aia kahi kūpono ma muli o ka wai / sima. 'O ia ho'i, ka lalo iho o kēia kaioke,'o ka'oi aku o ka ikaika o ka sima. He nui nā'ano nui o 200 he nui ('o kēia wale nō kona "li'ili'i"). E pi'i ana ia i 2,400 kg / m3. He mea kūpono kēia mahele no nā hale e ho'okomo i ka halihali, nā koluma, nā kī'aha, a pēlā aku. Loa ka nui o ka wai i ka pa apŘ o ka pōhaku puna mea kiʻekiʻe a me ka ia i ka haʻahaʻa plasticity. Ua ua hoʻohana 'ia no ke kumu o ka ipu, makapo wahi a puni o ka hale , a no laila, ma luna o.

Aia kekahi hewa e hana pinepine'ia i ka ho'opili'ana i kahi pane. Ma ka'oihana hale kū'ai, nui ka wai e ho'ohui'ia, kahi e ho'ēmi ai i ka māmā o ke ka'a a ho'onui i kona ka'a. Ho'ololi nui kēia i kona ikaika.

No ka hui, he ho'ohālike i hana'ia no ke kumu, nā'ano o nā mea hō'ili'ili a me nā mea hō'ailona, nā kūlana o ka pa'akikī a me kona hale. Ma ka manawa i oleloia ai, e hiki ke koho maʻamau (no ka kanawai a me ka hanalima hale) a kūikawā (alanui e kukulu, thermal'īpale, hydro a me ka meaʻai hana) pōhaku puna.

Ma nā'ano o ka mea hana pa'a e hiki ke hana'ia i plaster, silicate, sima, kauka-alkaline (pahu kila, hana'ilika, a polymer paha). 'O nā'ano o kona mau kī'aha he'ano like'ole: porous, pa'akikī a kūikawā, a he lean, momona a me ka waiwai o kona waihona. Eia kekahi, o ke kalaika o ke kopa, hiki ke loli, ka palau, ke kikooho a me ka palahalaha nui. 'O nā kumu no ka pa'akikī:'o ke'ano, ka mahana, ka mahana a me ka mālama'ana i ka mīkini i ka'awa honua a i'ole ka autoclave.

'O ka hō'ailona nui ma nā hi'ona o ke ka'apili,'o ia kona ikaika ikaika. Ua Ho'ākāka ' pōhaku puna papa. Eia kekahi la'ana, ka nui o ka pahu B25. Kēia 'o ia hoʻi i ka 95% o keia ano, e pale aku i ka puʻe o 25 MPa. 'O ia, ka huapalapala "B" a'o nā helu e hō'ike ana i ke kaomi e hiki ke ho'opa'a'ia i ka megapascals. I ka helu'ana i ka helu ho'olālā ikaika, pono ia e no'ono'o i nā heluna o ka ikaika compressive. 'O kēia ka mea kūpono no ka māmā o ke kaha B25. Makahiki o ka pōhaku puna i loko o olelo o kona papa, e e hooponoponoia ia mea, ma ka ikaika a me ka compressive iho hoʻopilikia, a ua häʻawi mai i kekahi manao ke kahua. 'O nā'ano hana o ke kūkulu'ana a me nā hana hana ma luna o ke'ano, a me nā'ano no ka ho'opa'akikī'ana i ke koi'ia, e mālama'ia.

'O ka māmā o ka pahu B 25 he mea kūpono ia no ka papa pōhaku, nā kumu monolithic, nā loko wai. 'O kēia ka mea i ho'ohana pinepine'ia no kēia mau hana. Eia hou, ho'ohana nā mea hale i kēia'enehana no nā'enehana'ē a'e o ke kuleana. 'O ka māmā o ka pakuhi Ma 25 ka mea e hiki ai ke hō'oia'i'o i ka maika'i maika'i o nā hale i ho'opau'ia, i ho'olako'ia,'oiai,'o ka waiwai i kū'ai'ia e mālama piha i nā'ano i ha'i'ia.
