Qhob M350: yooj yim yam ntxwv thiab daim ntawv thov

Qhob M350 - zoo heev siv cov ntaub ntawv uas, uas tso cai rau ua ib tug tseem ceeb heev lug rau txawv hom phiaj thiab txawv prefabricated ntsiab. Tom qab nws curing muaj pes tsawg leeg raws theem ntawm resilience, muaj zoo yam ntxwv, tshwj xeeb yog compressive zog. Nyob rau hauv niaj hnub siv yog lub pob zeb ua hauv chav kawm ntawv B25 yog ib tug thawj coj ob leeg nyob rau hauv cov nqe lus ntawm muaj koob meej, raws li kev muag khoom.

Daim ntawv thov cov ntaub ntawv uas

M350 qhob chav kawm ntawv B25 yog siv nyob rau hauv txhua hom kev tsim kho. Los ntawm nws yog ua slabs, cov khoom me nyuam yaus, cov phab ntsa, beams, txhua, qhob lug thiab lwm yam ntxwv ntsiab ntawm thaj, muaj thiab chaw ua hauj lwm vaj tse, nqa hnyav loads. Tsis tas li ntawd no mortar ua txoj kev airfield daim hlau ua nyob rau hauv lub siab tshaj plaws load.

Peb xav txog nyob rau hauv kom meej lub yam ntxwv muaj los ntawm lub tsev cov ntaub ntawv uas.

yam ntxwv ntawm

Xav txog ib co ntawm cov kev ntsuas ntawm lub dag lub zog nyob rau hauv compression. Nws yog ntsuas nyob rau hauv MPa, txiav txim los ntawm cov chav kawm ntawv B25 (1 cubic meter. Material tsis compromising lub sam xeeb tau mas siab ntawm 25 MPa). B25 nce lub zog yog tiav los ntawm qhov kuaj nyob rau hauv lub ntoos sib xyaw ntau xis mas. Nyob rau hauv tas li ntawd mus rau lub zog ntawm qhov no hom ntawm cement muaj lwm yam, sib npaug ib qho tseem ceeb yam: te kuj, dej kuj thiab muaj.

muaj

Qhov no piv txawv nyob rau hauv qhov tseem ceeb ntawm lub P2 rau P4. Tab sis cov theem ntawm lub dag lub zog muaj peev xwm muab tau ntau zog rau ntau dua qhov tseem ceeb thaum qhob yog supplemented los ntawm tshwj xeeb additives - plasticizers.

impermeability

Qhob B25 puas qhia ntawm permeability - W8. Qhov no parameter ntawd hais tias cov ntaub ntawv uas yog tsis muaj peev xwm kis tau los ntawm dej txawm yog hais tias nws ua rau nws nyob rau hauv tseem ceeb siab. Vim li no cov pob zeb qib M350 yuav siv tau nyob rau hauv tej thaj chaw uas muaj nqhuab rooj.

te

Qhov taw qhia ntawm te kuj F200 qhia hais tias qhov no cov ntaub ntawv uas tsis plam nws lub zog thiab yam ntxwv ntseeg tom qab ob puas thiab khov-thaw mus. Tej vaj tse yuav siv tau nyob rau hauv hnyav tej kev kawm.

ntim hnyav

Qhov no Performance index nyob rau hauv lub pob zeb M350 yog 1800-2500 kg / m³. Txawm li cas los, feem ntau lub ntim qhov ceeb thawj (density) ntawm cov khoom yog hom twg los ntawm 2200 mus 2400 kg / m³.

ntsiab Cheebtsam

Qhob M350 yog feem ntau nyob rau hauv daim ntawv ntawm ib tug sib tov ntawm MAAs, dej, xuab zeb thiab cov khoom muab tub lim, xws li gravel los yog crushed pob zeb granite. Yuav kom txhim kho lub zog ntawm cov khoom nyob rau hauv nws cov muaj pes tsawg leeg yog admixed additives thiab plasticizers, li no expanding lub Scope ntawm no qib ntawm qhob

Zus tau tej cov tshuaj B25 qib siv:

• MAAs;
• xuab zeb;
• gravel;
• dej;
• plasticizers;
• dej ntsuab additives.

Nws yuav tsum tau muab sau tseg tias yam siv los npaj cov tshuaj tej zaum yuav muaj kev txawv nyob rau hauv lawv tus yam ntxwv thiab tsis, namely, particle loj, me, lub zog, kev coj dawb huv, ya raws.

Piv txwv li, raws li ib tug tub lim yuav ua tau:

• zoo-grained xuab zeb, loj los yog nruab nrab feem;
• gravel (limestone los yog granite);
• crushed pob zeb thiab kuaj.

Tsis tas li ntawd muaj nqis ntsoov teev yog hais tias lub pob zeb B25 muaj ib tug ntau dua feem pua ntawm cov xis mas cov ntsiab lus, uas muaj txhawb rau ib tug txaus sai solidification.

proportions

Rau qhov kev npaj ntawm 1 m ³ ntawm cov ntaub ntawv uas yuav tsum tau:

• 400 kg Maas M400 los yog M500;
• 752 kg ntawm cov xuab zeb, lim los ntawm impurities;
• 175 litres ntawm cov dej;
• 1 m khoom muab tub lim (e.g., gravel).

Nyob rau hauv thiaj li yuav tau high-zoo thiab ruaj qhob M350, nws yog ib qho tseem ceeb tsis tau tsuas yog ua raws li ncaj qha nrog cov kev faib ua feem ntawm muaj pes tsawg leeg ib 1 m ^3, tab sis sib tov meej tag nrho cov Cheebtsam hais tias tus uas ua loj yog homogeneous. Tsis zoo mixed muaj pes tsawg leeg ho thiaj li lub dag lub zog ntawm cov khoom.

Kev npaj ntawm cov tshuaj

• Ua ntej, koj yuav tsum tau qhov tov khoom rau ntxiv cov khoom xyaw qhuav (cement thiab xuab zeb) thiab sib tov meej.
• Ntxiv cov dej. Rau ntawm no theem qhov kev daws tau poured mus rau hauv ib tug plasticizer los yog lwm yam additive.
• Ntxiv soaked nyob rau hauv dej rubble los yog gravel.
• Cov tshuaj yog kom huv si mixed.

Qhob M350: nqi

Manufacturers teem lawv tus kheej tus nqi rau cov ntaub ntawv uas los ntawm kev ntxiv mus rau tag nrho cov nqi, feem ntau ntawm uas ntog rau rubble thiab xis mas. Rau profit yog lub khw muag khoom paj tau paj saum toj no tus nqi. Yog vim li cas txhua txhua chaw tsim tshuaj paus puv "tus kheej" qhov kawg tus nqi ntawm uas yog kev lom zem ntau nyob rau raw khoom nqi.

Txhua tsim xaiv leej twg yuav ua vaj tse M350. Qhov nruab nrab nqi ntawm cov khoom no nrog ib tug gravel puv uas tsis yog-tus me nyuam yuav tsum yog los ntawm 3 000 p. rau 1 cubic meter ntawm sib tov, nrog ib tug granite gravel - 3 700 rubles.

Yog hais tias nkag tau dej ntsuab additives, tus nqi yuav pib thaum 4000 rubles. Tsis tas li ntawd nyob rau hauv tus nqi ntawm qhob yog los ntawm nws cov dej kuj - tshaj daim duab saum toj no, tus nqi yog kim kim. Yog li, peb yuav xaus uas tus nqi ntawm cov khoom nyob rau hauv lub chaw tsim tshuaj paus thiab tus nqi ntawm nrhiav tau ntawm puas yam.
