Slurry: zoo tagnrho proportions rau lub sib tov

Niaj hnub nimno siv yog ib qhov nyuaj rau xav txog tej yam tsis muaj kev siv ntawm ib cov khoom xws li xis mas. Qhov no yog ib tug ncaj pheej yig tsev cov ntaub ntawv uas, uas muaj ib tug xov tooj ntawm cov nta thiab cov yam ntxwv uas ua rau nws yuav luag universal.

Kev siv cov MAAs

Maas mortar, kev faib ua feem ntawm uas nws Cheebtsam yog txhais los ntawm nws lub hom phiaj, yog siv rau ntau yam hom phiaj. Firstly, nws yog - lub tseem ceeb tshaj plaws feem ntawm qhob raws li nyob rau hauv cement; Secondly, ib tug cib feem ntau yog muab tso rau xis mas. Ntawm lwm yam, tsis muaj grout yuav tsis ua li ntawd nyob rau hauv cov txheej txheem ntawm lub hauv pem teb Screed los yog plaster phab ntsa.

Muaj pes tsawg leeg grout

Koj yuav tsum tau ua tau qhuav maas, xuab zeb, dej thiab zoo ua ib pawg los npaj ib tug high-zoo xis mas. Lub proportions ntawm qhov yooj yim Cheebtsam - xuab zeb thiab xis mas - oscillate, feem ntau nyob rau hauv lub chav los ntawm 1: 2 1: 6. Nyob ntawm seb yuav ua li cas taub txua cov nqi ntawm cov khoom xyaw, cov tshuaj yuav tej yam khoom. Piv txwv li, yog tias ib tug daws yog mus ncuav rau ib tug ntau ntawm cov xuab zeb, nws qha siab zog, tab sis tsis nyob rau hauv plasticity thiab ductility. Yog hais tias lub MAAs hauv tshuaj ntau npaum li cas nws yuav yeej nyob rau hauv ductility, tiam sis yuav ua ho ua tsis tau zoo nyob rau hauv lub dag lub zog. Yog li ntawd, thaum lub MAAs slurry yog ua, lub proportions xaiv nruab nrab - 1: 3 los yog 1: 4.

Qhuav tshuaj

Yuav kom zuaj cov tshuaj zoo thiab nws cov khoom xyaw tov nyob rau hauv qhuav daim ntawv no. Nws yog tsim nyog tias txhua tus tivthaiv muaj ib tug high quality, qhuav, crumbly thiab tsis muaj lumps. Txwv tsis pub sib tov yog qhuav, nws yuav tsum tsim nyog los tshau los sis zom lumps. Tam sim no, thaum lub qhuav sib tov yog npaj txhij, ntxiv dej: ncuav nws maj mam, stirring sai sai. Nws yog ntseeg hais tias cov dej txaus cov taub hau thaum yaj tsa qab zib: ces nws yog sab laug rau 15 feeb, tom qab uas nws yuav siv tau rau lwm yam hom phiaj.

Txawm li cas los, thaum cov tshuaj no mixed MAAs, lub proportions nws zaum yuav ib nyuag txawv - piv txwv li, thaum txiv qaub yog poured mus rau hauv nws. Qhov no feature tsis tau tsuas yog tsub kom lub plasticity ntawm cov tshuaj, tab sis kuj nws lub zog. Standard piv MAAs: xuab zeb: txiv qaub - 1: 5: 2.

additives

Yuav kom muab tau ib tug tov ntawm tej yam ntxiv nta, additives yog feem ntau siv nyob rau hauv MAAs cug. Qhov no plasticizers, tej yam modifiers, superplasticizers, waterproofing thiab txhawb cov neeg ua hauj, thiab pigments. Assignment ntawm txhua additive yog cuab kev plasticizers thiab tej yam modifiers los txhim kho lub muaj ntawm cov tshuaj, ua MAAs ntau dua ywj thiab haum rau ib tug tej hom kev zov me nyuam (e.g., tiling). Waterproofing tsim nyog los txo cov teebmeem ntawm dej thiab dej nyob rau xis mas thiab qhob; reinforcing cov neeg ua hauj nce lub dag lub zog. Raws li rau cov xim, nws tsis nqa tej nuj nqi lwm yam tshaj li aesthetic: nws yog tsuas yog siv rau cov uas tseg tau cov tshuaj nyob rau hauv ib tug tej yam xim. Thaum koj ntxiv impurities mus rau hauv lub slurry, lub proportions yuav tsum muaj cai nrog txawm ntau dua precision, thiaj li tsis lwj lub sib tov nws tus kheej thiab yeej tsis phomsij rau cov yam ntxwv lub dag lub zog, uas ib tug tov yog ua.

Nws MAAs, coj mus rau hauv tus account uas nws sai sai hlob: nyob rau hauv ib teev thiab ib nrab, nws twb them nrog ib tug khoom ua kiav txhab. Yog li ntawd, nws yog ib qhov zoo tshaj plaws los mus sib tov nyob rau hauv me me xwb ua ntej yuav siv.
