Cov xuab zeb ua ke ntawm M400 lub npe yog rau pawg ntawm cov tsev sib xyaw ua ke nrog cov qauv zoo tshaj plaws rau kev ua tiav kev kho thiab rov ua haujlwm. Cov lus qhia yooj yim rau kev siv thiab xaiv ntau hom ("Birss", "Vilis", "Pob Zeb Paj", thiab lwm yam) tso cai rau koj xaiv thiab siv cov khoom siv rau nws lub hom phiaj hauv ntau yam kev mob. Nws tsim nyog kawm paub ntau ntxiv txog qhov nws txawv ntawm lwm hom, qhov zoo thiab cov yam ntxwv nws muaj.

Nws yog dab tsi?

Cov xuab zeb ua vaj tse ntawm M400 hom yog sib tov qhuav raws Portland MAAs, ua ke nrog cov xuab zeb ntxhib zeb thiab cov khoom tshwj xeeb ntxiv uas txhim kho nws qhov kev ua tau zoo . Ua tib zoo ntsuas qhov sib xyaw ua ke nrog cov yam ntxwv zoo ua rau cov khoom no muaj txiaj ntsig zoo rau siv hauv kev tsim kho thiab kho dua tshiab. Qhuav xuab zeb-pob zeb sib xyaw yog siv rau kev tsim cov tshuaj khib rau ntau lub hom phiaj.

Cov cim kev sib xyaw zoo ib yam li cov khoom siv tawv. Cov xuab zeb ua ke M400, thaum ua kom khov nyob rau hauv daim ntawv ntawm monolith, tau txais lub zog ntawm 400 kg / cm2.

Cov cim ntsuas ntxiv hauv daim ntawv lo qhia qhov kev ua kom huv ntawm cov khoom sib xyaw. Thaum tsis muaj cov tshuaj ntxiv, lub npe D0 tau muab txuas, yog tias muaj, tom qab tsab ntawv, feem pua suav nrog cov tshuaj ntxiv tau qhia.

Cov yam ntxwv tseem ceeb ntawm cov xuab zeb qhob M400 yog raws li hauv qab no:

• qhov nruab nrab lub lauj kaub lub neej ntawm cov tshuaj yog 120 feeb;
• ceev - 2000-2200 kg / m3;
• Frost tsis kam - txog 200 mus;
• tev lub zog - 0.3 MPa;
• kev ua haujlwm kub yog li ntawm +70 txog -50 degrees.

Kev nchuav M400 cov xuab zeb ua tiav tshwj xeeb thaum huab cua qhuav . Cov cua kub hauv tsev lossis sab nraum zoov yuav tsum yog yam tsawg +5 degrees Celsius. Kev nthuav dav ntawm daim ntawv thov ntawm cov khoom lag luam ntawm cov xuab zeb no txawv ntawm tsev neeg mus rau kev lag luam. Feem ntau nws yog siv thaum nchuav rau hauv pem teb screed, ua lub hauv paus hauv kev ua haujlwm, thiab lwm yam kev tsim vaj tsev. Kuj tseem sib xyaw qhuav M400 tau siv thaum nrum cov khoom lag luam. Lub lauj kaub luv lub neej ntawm cov tshuaj (60 txog 120 feeb) yuav tsum tau npaj tam sim ua ntej siv.

Cov xuab zeb ua ke ntawm M400 lub npe tau siv dav hauv kev lag luam thiab kev tsim kho pej xeem.

Thaum nchuav cov pob zeb ua kom muaj zog, tsim cov khoom hauv av, cov tshuaj tau muab rau hauv cov khoom tshwj xeeb . Hauv thaj tsam ntawm kev tsim kho tus kheej, nws tau kneaded rau hauv plaster sib tov. Tsis tas li, los ntawm cov khoom siv no, cov khoom siv ua vaj tsev tau tsim - cov nplais, thaiv, pob zeb.

Muaj pes tsawg leeg thiab ntim khoom

Cov xuab zeb zeb M400 muaj nyob hauv pob 10, 25, 40 lossis 50 kg. Nws tau ntim rau hauv hnab ntawv thiab khaws cia rau hauv qhov chaw qhuav. Cov muaj pes tsawg leeg tuaj yeem sib txawv raws li lub hom phiaj ntawm kev sib xyaw. Nws lub hauv paus tseem ceeb yog cov hauv qab no.

1. Portland MAAs М400 … Nws txiav txim siab qhov kawg ntawm lub zog ntawm cov pob zeb tom qab nws tau nchuav thiab ua kom tawv.
2. Dej xuab zeb ntawm cov feem ntxhib … Txoj kab uas hla yuav tsum tsis pub ntau tshaj 3 hli.
3. Cov yas yas tiv thaiv kev tawg thiab ntau dhau ntawm cov khoom.

Ib qho tshwj xeeb ntawm kev sib xyaw nrog cov cim M400 yog cov ntsiab lus nce ntxiv ntawm Portland MAAs. Qhov no tso cai rau nws muab lub zog siab tshaj plaws, ua rau nws muaj peev xwm tiv taus cov haujlwm ua haujlwm tseem ceeb. Qhov ntim ib feem ntawm cov xuab zeb sib sau ua ke hauv qhov sib xyaw nce mus txog 3/4.

Cov txheej txheem tsim khoom

Cov xuab zeb ua vaj tse ntawm M400 hom, nthuav tawm ntawm Lavxias lag luam, yog tsim los ntawm cov tuam txhab loj. Cov npe nrov tshaj plaws suav nrog cov hauv qab no.

Rusean . Lub tuam txhab tsim cov khoom lag luam hauv 50 kg hnab. Cov xuab zeb ua vaj tse ntawm cov khoom lag luam no tau ua tsaug rau nws qhov kev tiv taus kub heev, nce lub zog yam ntxwv, thiab muaj kev ntseeg siab ntawm monolith. Tus nqi tsim khoom yog qhov nruab nrab.

" Vilis ". Hom tshuaj no ua kom muaj cov xuab zeb zoo sib xyaw ua ke nrog ntau yam kev siv. Cov khoom yog tiv taus kom shrinkage thiab yog kev lag luam hauv kev siv. Cov pob ntim tau yooj yim ua ke nrog kev siv nyiaj txiag ua rau cov khoom no yog kev yuav khoom txaus nyiam tiag tiag.

" Pob Zeb Paj " … Cov khoom siv hauv tsev tsim khoom no tsim nws cov khoom raws li qhov xav tau ntawm GOST. Cov khoom lag luam tau txiav txim siab ua kom tau zoo, cov xuab zeb ua ke tau siv nyiaj txiag, ntxhib-ntxig rau sau, tiv taus ntau qhov khov thiab thaws mus.

Birss . Lub tuam txhab tsim cov khoom sib xyaw ntawm M400 hom nrog txo qhov muaj peev xwm ntawm kev daws teeb meem, qhov nruab nrab noj cov khoom siv raw. Cov xuab zeb ua kom tawv tawv tsis pub dhau 3 hnub, tiv taus ntau yam ntawm cov khoom siv thauj khoom.
