Tei te taimaha o te raima motuhake i runga i tona momo

huaina He kohatu horihori whakaputaina nei e te ranu wai, sima me māpele (kirikiri, onepu kirikiri ranei), a atu ratou solidification te raima.

Ka rite ki timata te rauemi hanga ki te whakamahi i roto i nga wa onamata te hanganga raima i ka taa mārika i i te hakari. He ko he wa ka i mutu ia i te wa o te whakamahi, engari i roto i te rau tau XIX i whakaaro uwhi waipēhi hou, pērā i, rongonui mo te tauira, Portland sima, me raima anō-riro i roto i te hanga. I roto i 60-doma o rau XIX. I ake te reira i te hangarau ahumahi sima, nui haere waitohu kaha, a ka whakamahia ai rite i tētahi ruruku matua mō te raima. I te kau tenei hua - tetahi o nga rauemi tino nui whakamahia i roto i te tata katoa ngā wāhanga o te hanganga hou.

āhukahuka taua, riro ia te whakawhetai ki te āhuatanga e whai ake nei:

• momo o ngā āhuatanga riro e tika ana ki ngā rerekētanga i roto i te kounga o te whakamahi o ngā rauemi kohatu me nga hononga, me te whānuitanga o ngā huarahi physicochemical me tukatuka aunoa;
• noho o te mahi ki te ranunga raima, e kua he ngāwari tiketike, me te taea ki te hanga motupaika i te whānui o ngā āhua me ngā rahi o roa, hanganga whare tiketike momo;
• taea tino ki mechanize te tukanga o te mahi ki te raima;
• ōhanga, ka rite ki tona rōrahi e 80-90% ngā o kohatu Ngā production rohe.

Ko taea anake Production o ngä raima kounga tiketike ki te matauranga o te hangarau, te kōwhiri i ngā rauemi pūkenga etahi kounga me te kaha ki te tātai i to ratou ōwehenga, ki te kitea tikanga styling, hiri, me te ranu aratau.

Hoki te hanga o ngā hanganga engineering te whakamahi i ngā momo rerekē o te raima (i roto i runga i te tono rānei). He maha ngā āhuatanga nui, e te hunga rauemi whakarōpūtia: te taimaha o te raima, me tona kaha, te momo o te kōpaki, te whakaaro me te huka motuhake. hanga te whakarōpū matua kei runga i te taimaha rōrahi. Nä ki a ia, he tino concretes marama, marama, taimaha, me te anō taimaha.

1. I roto i te tuatahi - he maha nui o reo, me te iti pūtau e pā ana ki 1-1.5 mm i te rahi o, na kua huaina pūtau hoki ratou. Ko te taimaha o te rōrahi raima o te 1 mita pūtoru motuhake ko e pā ana ki 500 kg. Tikanga, whakamahia tenei ahua te rite apa wera-tuuraa i.

2. Light. Tenei momo ngā hunga hoki e rite te puriwāhi whakamahia rauemi Kōmāmā ohie - whakawhānui paru, tuff, rakushnik, ranei atu e kore e whakamahi i tetahi taima, me te huka māngai e tapiritia -. Raima, raima aerated me etahi atu te wahi o te rōrahi raima i roto i te mita pūtoru - 500-1800 kg. Ko te wahi matua o tona hanganga e te onepu - ki runga ki te 600 kg. Kei te maha whakamahia taua rauemi mō te hanga o poraka whare.

3. Hei wāhanga o te raima taimaha he māpele krupnofraktsionnye taimaha - kirikiri me te kohatu mongamonga. Kotahi mita pūtoru o reira e ata whakaaro āhua 1800-2500 kg. E whakaatu ana tēnei mata 1150-1300 kg o kirikiri ranei kohatu i kurua, onepu 600-750 kg, 250-450 kg o sima, 150-200 rita o te wai. raima taumaha ko te aronui, me te whakamahia i roto i te maha ngā wāhanga o te hanganga.

E tito 4. concretes ngā taimaha o barite, magnetite, me etahi momo o te mau whakarewa. Ko te motuhake taimaha o te raima kia rōrahi o te 1 mita pūtoru i 2500 ki te 3000 kg. Ko te wāhanga matua o te nuinga o tona papatipu he töpü makaka. whakamahia tēnei momo o te raima te matua mo te hanga o ngā hanganga tiaki ki AEC.

Counting mita pūtoru o raima, e kore matou e wareware e kia whai ona wāhanga rerekē mahara motuhake. Hei tauira, he māmā atu i te awa i te hautanga iti o te töpü pokepoke uaua me rua onepu.
