Slurry: hanganga pai hoki te ranunga

he uaua hanga Modern ki whakaaro i waho te whakamahi o te rauemi pērā i te raima. Ko te rauemi hanga tika ngāwari, e kua he maha o ngā āhuatanga me ngā āhuatanga e hanga i taua tata te ao tenei.

Ko te whakamahi o te sima

moata sima, te rahi o e tautuhia e tona whakaaro nei wāhanga, kei te whakamahia hoki ngā take. Tuatahi, ko reira - te wāhanga tino nui o te raima i runga i sima; Tuarua, ko te pereki te tikanga hoatu i te reira ki runga ki sima. I roto i te tahi atu mea, kahore grout kore e taea te mahi i taua i runga i te rārangi take o te screed papa taiepa te raima ranei.

grout Composition

Ka Me koe ki sima mau maroke, onepu, wai, me te töpü pai ki te faaineine i te sima-kounga tiketike. Ko te hanganga o nga wae taketake - onepu me te sima - oscillate, te tikanga i roto i te whānuitanga o i 1: 2 ki te 1: 6. Runga anō i moni pehea metered o kai, riro te otinga etahi āhuatanga. Hei tauira, ki te mea te otinga ko te ki te ringihia he rota o onepu, whakaatu reira kaha nui, engari ngaro i roto i plasticity me te kōngohe. Ki te nui e riro i te sima ki otinga ia i roto i te ukanga, engari ka waiho tino iho i roto i te kaha. Na reira, ka hua te slurry sima ko, te hanganga reo tīpakohia - 1: 3 1 ranei: 4.

otinga production

Hei te pokepoke i te kounga otinga, me e konatunatua ona kai i roto i te puka maroke. E mea titauhia e ia wae he kounga teitei, maroke, kua puruhekahekatia me kahore kapia. Kore he maroke te ranunga ka waiho reira e tika ana ki te tatari i te huri kapia ranei. Na, ka he rite te ranunga maroke, tāpiri wai: ringihia reira āta, te whakaoho hohoro. Kei te whakapono te reira i taua wai rawaka ōritetanga, ka rewa rite kirīmi: na te mahue ai mo te 15 meneti, i muri nei e taea te whakamahi i te reira no te tahi atu mau opuaraa.

Heoi, ka te otinga ko sima whakauru, nga hanganga kia paku rerekē ai - mo te tauira, ina kua ringihia kotakota ki reira. Tenei āhuatanga faarahi kore anake te plasticity o te otinga, engari ano hoki tona kaha. Paerewa ōwehenga sima: onepu: kotakota - 1: 5: 2.

tāpiritanga

Hei hoatu i te otinga o tetahi atu āhuatanga, maha e tāpiritanga whakamahia i roto i te paru pokepoke sima. Tenei plasticizers, pūtohu pānga, superplasticizers, wuru me māngai whakaū, me ngā uhi. Taumahi o ia tāpiri ko plasticizers mārama me pūtohu pānga ki te whakapai ake i te nekeneke o te otinga, hanga sima atu rapa, me te tika mo te tetahi momo o te mahi (hei tauira, taera). Wuru e tika ana ki te whakaiti i te pānga o te houku me te wai i runga i te sima me raima; whakanui i whakapakari āpiha te kaha. Ko te ngarahu, e kore e kawe reira tetahi mahi atu atu i rerehua: Kei te anake whakamahia ai mo te otinga poke i roto i te tetahi te tae. A, no te tāpiri koe poke ki te slurry, me hei maharatanga te hanganga ki pū noa rahi, kia rite kore ki te pahua i te ranunga iho, a tino e kore hopohopo ki te kaha hanganga, ki i whakaputaina he otinga te.

Mixing sima, tango ki pūkete e ia hohoro kapo mai: i roto i te haora, me te hawhe, ka hipoki ia ki te kirinuku mārō. Na reira, ko te reira pai ki te uru i roto i wahi iti i mua i tika te whakamahi.
