Cov kev luj ntawm lub pob zeb ua yog nyob ntawm nws hom

Ib tug dag pob zeb uas yog ua los ntawm nws cov dej, MAAs thiab aggregates (gravel, xuab zeb los yog gravel), thiab ntxiv lawv solidification yog hu ua pob zeb.

Raws li ib tug lub tsev cov ntaub ntawv uas pib yuav tsum tau siv nyob rau hauv ancient sij hawm lub pob zeb ua muaj pes tsawg leeg uas ces differed markedly los ntawm cov tam sim no. Muaj ib lub sij hawm thaum nws raug nres thaum lub sij hawm ntawm qhov kev siv, tab sis nyob rau hauv lub XIX xyoo pua yog invented tshiab hydraulic binders, xws li, piv txwv li, Portland MAAs, thiab pob zeb ua re-tau chaw nyob rau hauv kev tsim kho. Nyob rau hauv 60-ies ntawm XIX caug xyoo. Nws twb zoo MAAs raug technology, hom zog nce thiab nws yog siv raws li ib tug lub ntsiab phau ntawv rau pob zeb ua. Thaum lub caij cov khoom no - ib qho ntawm feem tseem ceeb cov ntaub ntawv siv nyob rau hauv txhua qhov chaw uas niaj hnub siv.

Tej paub, nws tau txais ua tsaug rau cov nram qab no cov yam ntxwv:

• ntau yam ntawm cov khoom mas yuav kis tau vim variations nyob rau hauv qhov zoo tshaj ntawm kev siv ntawm cov pob zeb cov ntaub ntawv thiab binders thiab ib tug ntau yam ntawm txoj kev physicochemical thiab txhua yam ua;
• tsis ua hauj lwm nrog qhob mix, uas muaj ib tug high yooj thiab tso cai rau los tsim ib tug ntau yam ntawm cov duab thiab ntau thiab tsawg ntawm check, siab tsev lug;
• tau siab rau mechanize tus txheej txheem ntawm kev ua hauj lwm nrog qhob;
• kev khwv nyiaj txiag, raws li nws volume los ntawm 80-90% muaj pob zeb aggregates zos lawm.

Qhuav uas zoo ua vaj tse mix no tsuas tau nrog paub txog cov kev technology, xaiv cov ntaub ntawv kev txawj ntse tej zoo thiab muaj peev xwm los xam lawv ratio, mus nrhiav txoj kev styling, cov ntsaws ruaj ruaj thiab nws hom.

Rau qhov kev siv ntawm ntau yam engineering lug siv ntau hom pob zeb ua (nyob rau hauv nyob rau hauv daim ntawv thov). Muaj ntau ntau ib qho tseem ceeb nta, uas yog classified cov ntaub ntawv uas: cov kev luj ntawm lub pob zeb ua thiab nws lub zog, lub hom phau ntawv, lub hom phiaj thiab te. Lub ntsiab kev faib no yog ua rau cov volume ceeb thawj. Raws li rau nws, concretes yog heev lub teeb, lub teeb, hnyav thiab ntxiv hnyav.

1. Nyob rau hauv thawj - ib tug tseem ceeb pes tsawg tus ntawm nruab nrab thiab me me hlwb ntawm txog 1-1.5 hli nyob rau hauv loj, yog li ntawd lawv kuj hu ua cellular. Cov kev luj ntawm pob zeb ntim ntawm 1 cubic meter yog hais txog 500 kg. Feem ntau, qhov no zoo yog siv raws li thaum tshav kub kub-insulating txheej.

2. teeb. Qhov no hom muaj xws li cov neeg uas raws li ib tug placeholder siv yooj yim sib cov ntaub ntawv - txhab av nplaum, tuff, rakushnik, los yog lwm tus tsis txhob siv tej fillers, thiab foaming ua hauj lawm yog ntxiv - ua vaj tse, aerated qhob thiab lwm tus. Cov qhia tawm ntawm lub pob zeb ua ntim rau hauv cubic Meter - 500-1800 kg. Lub ntsiab yog ib feem ntawm nws cov muaj pes tsawg leeg yuav siv sij hawm hauv cov xuab zeb - mus txog rau 600 kg. Tej ntaub ntawv uas yog feem ntau siv rau zus tau tej cov building blocks.

3. Raws li ib feem ntawm qhov hnyav qhob yog krupnofraktsionnye hnyav aggregates - gravel thiab crushed pob zeb. Ib tug cubic Meter ntawm nws nyhav kwv yees li 1800-2500 kg. Qhov no qhia tau hais tias kev tshuaj ntsuam 1150-1300 kg ntawm gravel los yog crushed pob zeb, xuab zeb 600-750 kg, 250-450 kg ntawm MAAs, 150-200 litres ntawm cov dej. Heavy qhob yog ib tug classic thiab yog siv nyob rau hauv ntau qhov chaw ntawm kev tsim kho.

4. Tshwj xeeb hnyav concretes yog muaj li ntawm barite, magnetite, thiab tej hom ntawm seem hlau. Cov kev luj ntawm lub pob zeb ua volume ntawm 1 cubic meter yuav tsum yog los ntawm 2500 mus 3000 kg. Lub ntsiab tivthaiv ntawm feem ntau ntawm nws cov loj yog ntxhib sau ua ib pawg. Qhov no hom ntawm qhob yog siv rau qhov siv thiab ua kev tiv thaiv lug rau AEC.

Suav cubic Meter ntawm qhob, peb yuav tsum tsis txhob hnov qab tias nws lub Cheebtsam yuav muaj ntau kev nqus. Piv txwv li, ib tug me me feem ntawm ntxhib sau ua ib pawg nyuaj thiab qhov xuab zeb yog yooj yim dua dej.
