Txij li thaum Soviet lub sij hawm, lub pob zeb M300 yog lub feem ntau ntau yam thiab nrov ntawm tag nrho cov uas twb muaj lawm hom. Nyob ntawm seb cov lo lus uas, thiab hloov cov muaj pes tsawg leeg ntawm sib tov tseem unchanged tsuas yog tus nqi ntawm MAAs ib cubic Meter, thiab nws yog sib npaug zos rau peb puas units, raws li evidenced los ntawm lub npe ntawm pawg no los ntawm cov khoom. Qhov seem Cheebtsam yog hloov tag nrho cov yam ntxwv ntawm qhob: ceev, dej kuj, te kuj. Tsis tas li ntawd MAAs, raws li muab tub lim zaum yuav raug xaiv gravel, limestone los yog granite. Granite muab lub loj tshaj cov khoom zog, durability thiab, raws li, lub siab tshaj plaws nqi.

Qhob M300 yog siv nyob rau hauv yuav luag txhua txhua cheeb tsam. Nws yog siv nyob rau hauv lwm yam thiab loj siv, nrog rau cov kev siv ntawm cov vaj tse, kev thiab muaj xwm, tso txoj kev thiab kev tiv thaiv cov lug. Qhov no hom yog nruab nrab nyob rau hauv nws tus yam ntxwv, yog li qhov kev thov rau nws yog heev loj. Nws yog lub feem ntau haum kev xaiv rau qhov kev siv ntawm cov me nyuam yaus, pouring monolithic lug, tso ntawm Pavements, footpaths.

Qhob M300 GOST muaj cov nram qab cov yam ntxwv:

1) piv ntawm lub dag lub zog B22,5.

2) Cov theem ntawm muaj - P2-P4.

3) Cov theem ntawm cov dej kuj - W6.

4) Cov coefficient ntawm te kuj - F150.

Cov tsis muaj txaus rau qhov kev siv ntawm complex lug raws li ib tug load-tau cov kabmob thiab tsis yog load-tau cov kabmob Cheebtsam. Lub formulation ntawm tib qhob chav kawm ntawv tej zaum yuav txawv, nyob ntawm seb cov mej zeej ntawm lub additives. Mas siv lignopan B4 los yog sodium nitrite nyob rau hauv lub caij ntuj no, thiab kuj plasticizers accelerators. Yog li ntawd, qhob M300 nqi fluctuates heev, qhov ntau yam nyob rau hauv lub ntoos sib xyaw, lub nws yog ntau dua. Tsis tas li ntawd, tus nqi ho cuam tshuam los ntawm seasonality. Piv txwv li, nyob rau hauv lub caij nplooj ntoos hlav thiab lub caij ntuj sov tus nqi ntawm qhob khoom nce los ntawm 20-25%. Yog li ntawd nws yog pom zoo kom yuav tag nrho lub tsev ntaub ntawv nyob rau hauv ua ntej mus rau txuag ib tug txiav txim nqi ntawm cov nyiaj. Qhov nruab nrab nqi rau ib cubic Meter ntawm npaj mix yog 3500 rubles. Ib tug 25 kg lub hnab yuav yuav rau 200-250 rubles.

Lug siv rau peskobeton M300 ntaus rings nyob rau hauv kav dej phwj dej, uas yog nyob rau hauv tej yam kev mob xws li cov humidity, kub hloov thiab lwm yam kev phiv yam. Lub optimum piv ntawm lub dag lub zog thiab elasticity tso cai nws siv nyob rau hauv qhov siv thiab ua monolithic slabs thiab pem teb slabs.

Tag nrho cov tsev pob zeb ua lug thiab vaj tse ntawm no sib tov yog yus muaj los ntawm lub siab coj kuj thiab durability. Tab sis qhov no yuav ua tau tiav los ntawm kev ua tau zoo tag nrho yuav tsum tau tej yam kev mob yog stacking tshuaj. Piv txwv li, los mus tiv thaiv lub tsim ntawm voids nyob rau hauv lub pob zeb yog poured, koj yuav tsum siv ib tug vibrating cov khoom. Nws tseem yog tsim nyog los mas tus txheej txheem hardening sib tov: xyuas kom meej tias muaj yog tsis muaj kub jumps, los mus tiv thaiv lub evaporation nto ywg dej dej. Raws li tag nrho cov kev nuances yuav tau nco ntsoov hais tias lub pob zeb Siv M300 yuav ua tau ib tug ntev lub sij hawm nyob rau hauv lub loj tshaj plaws tej yam kev mob.
