Material kohi ia nga āhuatanga rahi tātaitanga tino arotau 1 m3 o raima, me tūtohutanga

I te pae hanga o tetahi taumata, i te skyscraper ki te whare whenua, e kore e taea te mahi i waho raima. whakamahia tēnei rauemi kei te ki te whakaki i te turanga, hanganga o taiepa i roto i te hanga nukurau, nga patunga pūrere me nunui tonu i roto i te pereki, me ētahi atu kohatu horihori. Te faaineineraa o te raima i roto i te rahi e tika ana, e whakarato ana e kore anake te mauroa me te kaha o ngā hanganga, engari ano ki te karo i ngā utu rauemi faufaa.

Ko te hanganga o te raima

I roto i te take māmā, ngā te raima o e toru ngā wāhanga:

• Kōpaki.
• Filler.
• Water.

kohi Material ia 1 m3 o te raima tei runga i te āhuatanga o ēnei rauemi. Ka rite ki te ruruku whakamahia i roto i te hanga o te ranunga o tima tohu M100-M600 kaha. A, no te konatunatua ki te wai, hanga ana e ia he puranga Kaore i hanga nei i roto i solidification o te kohatu horihori. I roto i te tūranga o te filler onepu whakamahia te rerekē ranei momo o kirikiri. faarahi tenei te kaha o te otinga tio, rite runga ake kirikiri kaha kaha sima. I tua atu, ko te whakamahi o te filler te whakaiti te na'ina'iraa o te ranunga sima.

Haunga nga wähanga matua, i roto i te hanganga raima ngā ngā tāpiritanga, hoatu he otinga o ngā āhuatanga atu: ātete matao, ātete wai, tae, me te pera atu.

whakaritea te i te whakaritenga mahi o te ranunga - te kohi hiahiatia rauemi ia 1m3 raima - kirikiri, sima, onepu.

Ko te āhuatanga matua o te raima

Ko te huru tino nui o te raima - tona kaha shock. Runga anō i tona piha kaha whakapumautia. reta Denoted English "B" me ngā nama e ōrite ana ki te tauira i roto i MPa kaha. Te whakaputa akomanga raima i V3,5 ki B80, i roto i metarahi nga rongoā B15 tino hāngai ana - B30. I tua atu ki ngā akomanga, ki te tohu e taea te whakamahi i te kaha o te waitohu. Denoted reta Latin "M" me te tokomaha e ōrite ana ki te kaha i roto i kg / cm sq. Karaehe me waitohu kaua tika e pā ana ki tetahi ki tetahi, hei tauira, tutaki M200 otinga Class B15 me M300 V22,5 piha haapiiraa.

kohi Material ia 1 m3 o raima e taea rerekē tino i runga i te piha haapiiraa māka ranei otinga e hiahiatia ana rānei.

Me kï reira e takoto te piha raima tūturu te anake i roto i te taiwhanga i 28 ra. Na reira, ki te tika ki te tika mohio te hanga te ranunga, i te wā o te workpiece ki kia maka e rave rahi tauira - poraka ipurau 100 mm i roto i te tiketike o ranei. Pea ki te whakatau i te kaha o te raima he hoki tikanga mauhaa hama Kashkarova ranei, engari he iti tika enei tikanga.

Tīpakonga o te piha haapiiraa raima hiahiatia

Ka te kōeke e hiahiatia ana o te raima kia tohua i roto i te tuhinga hoahoa mo te hanganga kaupapa. Ki te kawea hanga i roto i runga i to ratou ake, e tautuhi tatou te ranunga waitohu, i te mea he reira ki te whānuitanga nui pā te kaha, me te uara o te whare hanganga ranei te whakaturia.

homai Wāhui o nga rama tino noa o te raima te raro nei.

• M100 - Whakamahia mō te parebrikov tāutanga pūrere taahiraa, puka iti hoahoanga;
• M150 - whakamahia i roto i te ara pūrere tautoko whakamutunga nohoanga;
• M200 - mo te whakaarahanga o te taiepa, haurangi;
• M250 - hokohoko turanga nukurau, grills, papa turanga, papa iti utaina, kaupae, pupuri taiepa ;
• M300 - mo tetahi hanganga utaina: taiepa, papa, turanga;
• M350 - amo taiepa, tīwae, papa, kurupae, turanga mārō.

tawhā onepu

No te faaineine i te otinga onepu whakamahia o ngā takenga mai: rua kohatu awa ranei. Ko atu pai te tuarua no te mea he rahi granule nui me e kore e roto i poke. kia rerekē rua onepu i roto i to ratou tohatoha rahi matūriki. Arā, te whakamahi i onepu ki reo me granules rahi nui. Mai taea te titoa te onepu rua kohatu o te uku atu poke ranei e tūtohu ana ki te tatari i roto i.

He mea tino nui ki te whakarongo ki te ihirangi makuku o onepu. Tei runga i tenei tau kia tāpiri ki te whakatika i te ranunga i roto i te wai. I roto i te tirohanga o te ihirangi makuku me te tohatoha rahi matūriki o te kiato nuinga o te onepu taea rerekē i 1.3 ki te 1.9 t / cu m, he mea e tika ana ki te whakaaro te tātai i te kohi o ngā rauemi ia 1 m3 o raima.

Tīpakonga o paru

Mongamonga ranunga raima arā, o te raima faarahi kaha, me te whakaiti i tona na'ina'iraa i roto i solidification. A, no te kōwhiri i te nui tino he kirikiri hautanga me tona takenga.

I roto i te hanga whakamahia hautau kirikiri:

• i 5 ki te 20 mm;
• i 20 ki te 40 mm;
• i 40 ki te 70 mm.

Tei runga i te kohatu mongamonga raw whakarōpūtia ki:

• Pākeho, e hāngai ana i runga i ngā toka parataiao.
• O horoia kirikiri otaota.
• Ofa'i whakaputaina e kuru toka ofa'i ofa'i-te kāhuarau kanapa, me te.

mahi Superior ki te kaha he ofa'i paru, na ki te rite te raima te mo te hanganga nui - turanga, tīwae, tuanui, he reira pai ki te whakamahi i te reira. He mea tika e kore e ki te wareware i whakamahia paru te kore e roto i poke, rawa paru.

ōwehenga wai-sima

A, no te whakaputa uara tuatahi raima ko te ōwehenga o te sima me te wai. Ko e tika ana hoki te tauhohenga matū o te sima hydration wai, ārahi ki te hanganga o te kohatu sima. Ko crucially whakatau te piha haapiiraa o te ranunga raima tenei ōwehenga. He mea nui ki te tango ki pūkete te waitohu tsementa.Chem raro wai-sima ōwehenga, te kaha te raima. Te ōwehenga iti rawa e hiahiatia mo te hydration o sima ko 0.2. I roto i te mahi, ki te whakamahi o te raima ki te wai rata ōwehenga 0.3-0.5. Ranunga ki te ōwehenga wai-sima tiketike kore whakaritea te whakamahia.

Whakatau i o ōwehenga ranunga raima

Ka rite ki te tikanga, mo te faaineineraa o te sima raima whakamahia tohu M400 me M500. I roto i te mahi, ki te whakatau i te kai o te sima ia 1m3 o te raima te whakamahi i te tepu e whai ake.

Enei raraunga Ko mō tikanga noa o te pāmahana, me te haumākū, me te sima, te tawhā o e hāngai ki te hunga tohua i runga i te mōkihi. I roto i te ora tūturu, kia whakarato sima te taikaha ko 10-15%.

I tua atu, kia rite ki te nui o te sima tatau i runga i te rauemi kohi 1m3 raima mohiotia, whakaaturia te rahi tino arotau o te sima ki onepu me te kirikiri e i roto i te tepu.

Hei tauira, te kohi rauemi ia 1 m3 o raima M200 ko: sima waitohu M500 - 240 kg Sand - 576 kg, kohatu mongamonga - 984 kg Water - 120 rita.

Production o raima

A, no te mahi ngā pukapuka nui o raima he mea tika ki te hoko i te whakato raima rite-whakauru i te whakaranu tuku tata. I roto i te te hanga ahumahi o rauemi reiti kohi ia 1 m3 o raima e puritia makona kaha. Ki te kore e taea tenei, ka taea e koe te whakarite i te nui e hiahiatia ana o ranunga me te kāinga. He mea nui ki te aromatawai tika ratou kaha - kia kawea concreting hanganga motuhake i roto i roto i te kotahi haere.

I mua i te ranu i te ranunga whakatau kohi rauemi ia 1m3 o raima. E kore te te tātaitanga o te auau rere tika te mahi nui ki te whakamahi i te ripanga i raro nei.

rite te ranunga te i roto i te nui whakaranu ōrite raima, whakapanga te reira i roto i metered wahi o sima maroke, onepu me te schebonki sieved. kia tāpiri Water i roto i nga wahi i roto i te tahuri whakamutunga.

tāpiritanga

I tua atu ki te kaipōti matua o nga tāpiritanga raima e tapiritia hoki ngā take:

• Kaiwhakahōu. E hangaia ratou ki te whakapai ake i te kaha me te whakapiki ake i te ātete huka o raima.
• Plasticizers. Whakanuia nekeneke me te ranunga waterproofness.
• Tauwehe nekeneke. Ka taea e whakawhānui i te wa tautuhinga, ki te pupuri nekeneke i roto i te waka.
• tāpiritanga Antimoroznye. Whakarato ringa noa o te otinga i pāmahana iti iho ki haunga te 20 nekehanga.
• Accelerator. Whakanuia te tautuhinga tere na roto i te whakarato i te haamărôraa tere i roto i te ra tuatahi.

I roto i te tono o tāpiritanga, kohi rauemi ia 1 m3 o te raima kia takoto tango ki pūkete nga tūtohutanga o te kaiwhakanao. Tūkinotanga o nga tohutohu mō te whakamahi taea whai rawa te pānga ritenga.
