Nhanho yekutanga: kuyedza alkalinity ye simenti

Edza kukosha kwepH yesimende yataurwa, uye shandisa pH, pH mita kana pH peni kuti uedze. Mhedzisiro yekuedzwa inogona kushandiswa kutanga kuona: kana huwandu hwealkali inonyungudika mu simenti yakakura kana diki; ingave yakasanganiswa mu simenti iine acidic kana inert zvinhu zvakaita seupfu hwebwe, izvo zvinoita kuti pH iderere.

Danho rechipiri: kuongorora

Chikamu chekutanga chekuferefeta ndechekuwana mhedzisiro yekuongorora clinker ye simenti. Verenga zviri mukati memaminerari mana esimende: tricalcium aluminate C3A, tetracalcium aluminoferrite C4AF, tricalcium silicate C3S uye dicalcium silicate C2S.

Chikamu chechipiri chekuferefeta ndechekunzwisisa kuti ndeapi ma admixtures anowedzerwa kana clinker yakagadzika kuita simende uye kuti yakawanda sei inowedzerwa, iyo inobatsira zvikuru pakuongorora zvikonzero zvekubuda ropa kwekongiri uye nguva yekuisa isina kujairika (yakareba, ipfupi).

Chikamu chechitatu chekuferefeta ndechekunzwisisa kwakasiyana uye kunaka kwekongiri admixtures.

Nhanho 3: Tsvaga iyo yakazara dosage kukosha

Tsvaga iyo saturated dosage kukosha kweiyo yakanyanya-inoshanda yekudzikisa mvura inoshandiswa kune iyi simende. Kana maviri kana anopfuura epamusoro-anoshanda emvura anoderedza akasanganiswa, tsvaga yakazara dosage poindi kuburikidza nesamende paste bvunzo zvinoenderana nehuwandu hwehuwandu hwemusanganiswa. Iyo iri padhuze dosage yeyepamusoro-inoshanda yekudzikisa mvura ndeye yakazara dosage ye simenti, zviri nyore kuwana zvirinani kuchinjika.

Nhanho 4: Gadzirisa dhigirii repurasitiki reiyo clinker kune iyo yakakodzera renji

Gadzirisa dhigirii re alkali sulfation mu simenti, kureva, dhigirii replasticization ye clinker kune rakakodzera renji. Iyo yekuverengera fomula yeiyo SD kukosha kweplasticization degree yeclinker ndeiyi: SD=SO3/(1.292Na2O+0.85K2O) Izvo zvemukati kukosha kwechikamu chimwe nechimwe zvakanyorwa mukuwongorora clinker. Iyo SD kukosha kwemhando ndeye 40% kusvika 200%. Kana yakanyanya kuderera, zvinoreva kuti kune shoma sulfur trioxide. Chikamu chiduku chesarufa-ine munyu se sodium sulfate inofanira kuwedzerwa kune yakasanganiswa. Kana yakanyanya kukwirira, zvinoreva kuti molecule yakakura, kureva kuti, pane sulfur trioxide yakawanda. Iyo pH kukosha kweiyo yakasanganiswa inofanirwa kuwedzera zvishoma, senge sodium carbonate, caustic soda, nezvimwe.

Nhanho yechishanu: Bvunza-musanganiswa anosanganisa admixtures uye tsvaga mhando uye dosage yekuseta vamiririri.

Kana jecha remhando yakashata, senge yakakwira madhaka emukati, kana kana jecha rese rekugadzira uye jecha rakanyanya kushandiswa kusanganisa kongiri, mushure meiyo mambure slurry bvunzo yawana zvinogutsa mhedzisiro, zvinodikanwa kuenderera mberi nekuita dhaka bvunzo kuti uwedzere kugadzirisa kuchinjika neiyo admixture.

Danho rechitanhatu: Concrete test For concrete test, chiyero chemusanganiswa hachifaniri kunge chiri pasi pe10 malita

Kunyange kana iyo mambure slurry yakagadziriswa zvakanaka, inogona kunge isingasviki zvinotarisirwa mukrete; kana mambure slurry asina kugadziriswa zvakanaka, konkrete inogona kuva nematambudziko makuru.Mushure mokunge chiyero chiduku chekuedza chichibudirira, dzimwe nguva yakawanda inoda kudzokororwa, yakadai se25 litita kusvika ku45 litita, nokuti zvigumisiro zvingave zvichiri zvakasiyana zvishoma. Chete kana imwe nhamba yekongiri bvunzo ikabudirira ndipo iyo inogadziriswa inogadziriswa inogona kupedzwa.

Danho rechinomwe: Gadzirisa kongiri musanganiswa ratio

Iwe unogona kuwedzera kana kuderedza huwandu hwemamineral admixtures zvakakodzera, uye shandura iyo imwechete musanganiswa kuita kaviri musanganiswa, ndiko kuti, shandisa maviri akasiyana admixtures panguva imwe chete. Hapana mubvunzo kuti kaviri musanganiswa zviri nani pane imwe chete musanganiswa; kuwedzera kana kuderedza kuwanda kwesamende kunogona kugadzirisa kukanganisa kwekongiri kunamatira, kukurumidza kudonha kurasikirwa uye kubuda ropa kwekongiri, kunyanya kubuda kwejecha; kuwedzera zvishoma kana kuderedza kuwanda kwemvura; kuwedzera kana kuderedza jecha reshiyo, kana kutochinja zvishoma mhando yejecha, senge musanganiswa wejecha rakakora uye rakanaka, jecha rechisikigo nejecha rekugadzira, nezvimwe.
