Qhob B15 (TM): muaj pes tsawg leeg, yam ntxwv

Qhob - tej zaum cov feem ntau uas cog noob tsev ntaub lug siv nyob rau hauv kev tsim kho ntawm ob leeg ntiag tug tsev thiab loj multi-storey vaj tse. Muaj ntau ntau hom ntawm cov khoom no rau siv nyob rau hauv ib tug ntau yam ntawm lub hom phiaj. Ib qho ntawm feem nrov yog ib tug qhob B15 (class) los yog M200 (TM).

General yam ntxwv

Qhob B15 (M200 cim) yog hais txog ib tug pab pawg neeg nrog ib tug txhais li cas degree ntawm lub dag lub zog ntawm 196 kgf / cm. Nws yog ua noj mus rau hauv tus account lub cai ntawm GOST uas niaj hnub khoom rau cia li ntau lawm kab. Cov no ib tug heev zoo cov ntaub ntawv uas haum rau qhov kev siv ntawm ib tug ntau yam ntawm cov yam ntxwv ntsiab ntawm cov vaj tse.

Scope ntawm kev siv

Qhuav muaj zog check flooring - lub ntsiab cheeb tsam ntawm daim ntawv thov ntawm no cov ntaub ntawv uas. Kuj mus phiv huab cua tej yam kev mob nws yog qhov nruab nrab. Thiab yog li ntawd nws yog zoo dua rau siv nws nyob hauv tsev. Screed siv cov khoom siv no muab ib tug heev txhim khu kev qha thiab check. Nyob rau hauv tas li ntawd mus no, ua vaj tse B15 - hom, siv nyob rau hauv:

• constructing cov me nyuam yaus (mas tsev neeg vaj tse);
• casting phab ntsa;
• manufacture ntawm qhob taug thiab curbs;
• pouring pavings;
• kev siv ntawm stairs thiab porches;
• tsim precast qhob khoom;
• pouring txhua;
• mus tsim lub substrate thaum lub sij hawm txoj kev ua hauj lwm.

Mark qhob B15: Muaj pes tsawg leeg

Ua ib tug txheej txheem qhob B15 siv cov nram qab no Cheebtsam:

• Maas (30 kg).
• Me aggregates (40 kg). Tau siv cov xuab zeb nrog ib tug particle loj ntawm 0.15 mus 5 hli. Nws ceev yuav tsum 1790 kg / m ^3.
• Crushed pob zeb los yog gravel (90 kg). Lis luaj li cas ntawm cov muab tub lim yog hom twg los ntawm 6 mus rau 70 mm. Nrog kev tsim kho ntawm loj heev lug tej zaum yuav siv crushed pob zeb fractions nrog ib tug loj mus txog 140 hli.

Qhuav Cheebtsam yog pre-tov meej thiab ces diluted nrog dej nyob rau hauv ib tug npaum li ntawm 20% ntawm tag nrho cov ntim. Tej zaum manufacturers los txhim kho qhov zoo ntawm cov khoom tiav yog ntxiv rau nws tag nrho cov xaiv ntawm cov minerals, plasticizers, thiab hais txog. D.

Nws yog tsim los ntawm qhob qib B15 (GOST 7473-2010) heev dua lwm yam los ntawm high-quality xis mas. Feem ntau cov feem ntau nws yog ib yam khoom ntawm lub hom M400. Lub ceeb thawj piv ntawm MAAs * * gravel xuab zeb nyob rau hauv proportions yuav tsum: 1 * 2.8 * 4.8.

hom

Tam sim no muaj nyob rau ob peb hom pob zeb ua nyob rau hauv nws chav kawm ntawv. Lawv yuav sib txawv, piv txwv li, nyob rau hauv hom muab tub lim siv. Qhov no yuav ua tau txiv qaub, granite gravel los yog crushed pob zeb. Tseem muaj ntau ntau yam ntawm cov khoom no nrog txawv degrees ntawm muaj thiab mob heev.

Qhov ratio ntawm cov hom thiab qib

Contrary kom nrov kev ntseeg, tom qab 28 hnub mus nce lub zog qhob tsis nres. Qhov no txoj kev muaj peev xwm noj tag nrho cov sij hawm khiav hauj lwm tsa los ntawm nws tsim. Mark qhob yog txiav txim nyob rau tus nqi ntawm cov xis mas siv nyob rau hauv nws raug. Qhov no qhia plays ib tug tseem ceeb heev luag hauj lwm nyob rau hauv lub peev xwm ntawm cov pob zeb ua los kom tiv thaiv compression thiab expansion. Nws yog ntsuas nyob rau hauv kgs / cm ^3. Yog li, lub stamp qhob M200 qhia tau hais tias lub tensile zog nyob rau hauv compression ntawm 200 kgf / cm ^3.

Nyob rau hauv tas li ntawd mus rau lub hom, thiab txawm lub pob zeb no tau muab faib mus rau hauv cov chav kawm ntawv. Raws li qhov no index txiav txim lub siab tshaj plaws siab ntawd mas hauv lub tiav lawm khoom nyob rau hauv megapascals. Nyob rau hauv no hais txog 15 mus rau 15 MPa (95%). Tus heev qhob hoob kawm yog denoted los ntawm tsab ntawv "B".

Yav tas los, nyob rau lub zog ntawm qhob twb txiav txim los ntawm lub hom. Tam sim no qhov no cov ntaub ntawv uas yog txwv kom muab zais mas mus rau hauv cov chav kawm ntawv. Tab sis rau cov neeg uas yog accustomed mus tsom rau lub hom, nws yog ntau yooj yim, teem tshwj xeeb ntxhuav, uas yog muab piv ntawm cov ob ntsuas.

Qib ntawm qhob rau lwm yam kev ntsuas

Durability - tsis yog parameter uas koj yuav tsum tau them nyiaj mloog thaum yuav ib lub sib tov. Ib tug heev ib qho tseem ceeb ntsuas no yog qhov tseem cov tshuaj rau cov tshuaj te. Nws yog xaiv los ntawm tsab ntawv F thiab cov zauv pib nrog 25. Nyob rau hauv kev xyaum, nyob rau hauv ib tug ntiav tsev-tsev kheev siv qhob nrog te hom F100-200.

Ib qho tseem ceeb parameter - cov dej kuj ua vaj tse. Nyob rau hauv cov ntaub ntawv no, cov ntaub ntawv uas tej zaum yuav sau tias raws li W2, W4, W6, W8 thiab W12. Cov nuj nqis qhia cov dej siab uas lub pob zeb kheej kheej 15 cm nyob rau hauv qhov siab yog cov dej ntawm ib tug tej yam siab. Qhob B15 hom yam ntxwv nyob rau hauv no hais txog yog zoo heev.

Tsis tas li ntawd, thaum yuav ua vaj tse yuav tsum xyuam xim rau kev qhia xws li cov hauv paus. Qhov no parameter qhia txog ib tug yam ntxwv maeriala li muaj. "P" yog cim los ntawm cov duab nyob rau hauv cov ntaub ntawv ntawv sib tov tsab ntawv. Feem ntau cov feem ntau siv nyob rau hauv kev tsim kho ntawm qhob nrog lub muaj ntawm P-2 thiab P-3. Solutions ntawm lub P-4 theem thiab saum toj no yog siv yog tias yuav tsum tau mus sau ib qho nyuaj mus cuag qhov chaw. Siv yas thiab qhob thaum casting yog tau siv ib tug twj tso kua mis.

kev yam ntxwv

Uas particular zog txawv B15 qhob (qib M200), muaj peev xwm yuav nrhiav tau nyob rau hauv lub rooj hauv qab no.

Tus nqi ntawm cov khoom

Nqi rau pob zeb ua hauv chav kawm ntawv B15 (M200 Hom) nyob ntawm seb tsuas yog nyob rau ntau yam siv nyob rau hauv qhov siv thiab ua rubble. Piv txwv li, yog hais tias nws yog granite, ib cubic Meter ntawm qhob B15 yuav tau them txog 3.850 rubles (raws li ntawm 2015). Rau cov embodiment nrog gravel muab tub lim - kwv yees li 3600 p.

Raug lub tsev

Tau high-zoo sib tov nyob rau hauv cov ntaub ntawv no nws yog ua tau, tsuas siv ib qhob tov. Xuas tes ua zoo pob zeb ua hauv chav kawm ntawv B15 hom M200 Knead tsis ua hauj lwm. Tus txheej txheem rau kev npaj ntawm cov tshuaj no raws li nram no:

• Ua tib zoo pre-mixed xuab zeb thiab xis mas. Rau ntawm no theem ib tug yuav ncuav lub additive uas tsub kom tus mob khaub thuas kuj (20 kg 2 kg ntawm MAAs).
• Tom ntej no, dej yog ntxiv, thiab ces lub crushed pob zeb.
• Cov uas ua sib tov yog do rau tsawg kawg peb feeb.

Lub volume piv ntawm B15 qhob (qib M200) yog npaj nyob rau hauv lub nram qab no proportions: 10 liv 19 litres yog coj MAAs xuab zeb thiab gravel 33 liters. Li ntawd, cov piv yuav kwv yees li lub thoob desyatilitrovyh: 1h2h3,5.

Nyob rau hauv lub chaw ua khoom ntawm pob zeb ua cim no sib txawv los ntawm predetermined ntau ratios ntawm tsis muaj ntau tshaj li 1%.

Piv txwv li batch

Rau ib columnar foundation caij volume 0,11 m ³ xav kwv yees li 19 kg MAAs, xuab zeb - 41 kg, tawg gravel - 78 kg ntawm cov dej - 9 kg. Qhov no piv yog siv tau thaum uas siv M400 hom ntawm cement. Yuav kom sau tus ncej yuav tau ua hais txog ob tug mixing.

Qhob lwm hom

Heev feem ntau nyob rau hauv lub private lub tsev-tsev siv thiab zoo ua vaj tse qib M250 (B20). Cov hom yog dog dig muaj zog tshaj hauv chav kawm ntawv B15 thiab muaj peev xwm yuav siv tau kuj rau casting slabs uas tsis raug kev txom nyem mob loj heev kev nyuaj siab. Qhob hom M300 (cov chav kawm ntawv V22,5) yog feem ntau siv rau kev tsim kho ntawm sawb cov me nyuam yaus. Yuav kom sau MDF khoom av nyob rau hauv lub tsev ntau zaus siv M350 tshuaj (B25 class).

Qhob B15 - hom zog, li ntawd, nws yog haum rau qhov kev siv ntawm feem ntau cov khoom nyob rau hauv lub private lub tsev lub tsev. Heev zoo ua yam ntxwv, nrog rau tus nqi qis ua rau nws ua tau siv ob mus sau cov Screed thiab cov plag tsev, thiab rau kev siv ntawm cov me nyuam yaus (hozpostroek) thiab partitions.
