Mehaho e hahiloeng ka konkreite M300. Features senotlolo

Ho tloha mehleng ea Soviet Union, ho M300 e hahiloeng ka konkreite ke fetisisa tenyetseha le ratoang tsa Brands tsohle tse teng. Ho itšetlehile ka eang teng, 'me e fetola ho hlophisoa ha motsoako o hlola ka ho sa fetohe feela ka tjhelete e ya samente ka mitha dikhubu,' me ke ba lekanang diyuniti tse makholo a mararo, e leng se pakoang ke lebitso la sehlopha sena sa thepa. Metsoako e setseng ba fetola litšobotsi tsohle tsa ka konkreiti: segokanyipalo, metsi ho hanyetsa, serame ho hanyetsa. Ho feta moo samente, ka filler ka 'na a khetha lehlohlojane, a lejoe la mokoetla kapa morema. Morema fana ka ho fetisisa sehlahiswa matla, durability le, e loketseng, litšenyehelo phahameng ka ho fetisisa.

Concrete M300 e sebelisoa ka hoo e ka bang mong le e mong sebakeng seo. E e sebelisoa ka kaho poraefete le kgolo, ho haha mehaho, botekgeniki le indasteri tlhaho, rala Litsela le mehaho e sireletsang. cha Sena ke karolelano ka litšobotsi tse lona, kahoo ho hlokahala ke e kholo haholo.

Concrete M300 GOST o na le litšobotsi tse latelang:

1) karo-karolelano ea matla B22,5.

2) boemo ba tsamaiso - P2-P4.

3) boemo ba metsi ho hanyetsa - W6.

4) The coefficient ya serame ho hanyetsa - F150.

Paakanyong ea tšoanang sehlopha sa ka konkreiti 'na tsa fapana, ho itšetlehile ka litho ho sebelisoe ka. Haholo-holo sebelisoa lignopan B4 kapa sodium nitrite ka mariha, 'me le tsona plasticizers accelerators. Ka hona, mabota a konkreiti a M300 theko fluctuates haholo, metsoako e feta ka motsoako, ho ho ke ke e phahameng. Hape, litšenyehelo haholo angoa ke seasonality. Ka mohlala, nakong ea selemo le lehlabula theko ea lihlahisoa tsa konkreiti s ea eketseha ka 20-25%. Ka lebaka leo, e kgothaletswa ho reka thepa eohle mohaho esale pele ho boloka chelete e khōlō ea chelete. Theko karolelano bakeng mitha dikhubu mong oa loketse Remix ke 3500 li-ruble.
