Mhedzisiro yemuchina-yakagadzirwa jecha mhando uye admixture kuchinjika pane kongiri mhando

Iyo mai dombo uye tekinoroji yekugadzira yejecha rakagadzirwa nemushini munzvimbo dzakasiyana dzakasiyana zvakanyanya. Kunyura kwemvura kwejecha rakagadzirwa nemuchina kunokanganisa kudonha kwekongiri kune imwe nhanho, uye kuwandisa kwedhaka poda mujecha rakagadzirwa nemushini hakungokanganisa simba rekongiri, kunyanya kudzoka kwakasimba. Elastic simba uye kusimba, zvichikonzera chiitiko chehupfu pakona yekrete, uye zvakare isingafadzi yekudzora mutengo wemusanganiswa chirimwa. Iyo fineness modulus yejecha rakagadzirwa parizvino iri 3.5-3.8, kana kunyange 4.0, uye gradation yakaputsika zvakanyanya uye haina musoro. Chikamu chiri pakati pe1.18 ne0.03mm idiki kwazvo, zvinova zvinonetsa pakupomba kongiri.

1. Panguva yekugadzirwa kwejecha rakagadzirwa nemichina, zvinyorwa zvehupfu hwematombo zvinofanira kunyatsodzorwa kuti zvive ne6%, uye zvinyorwa zvevhu zvinofanira kunge zviri mukati me3%. Zviri mukati mehupfu hwematombo ndeyekuwedzera kwakanaka kwejecha rakaputsika rakagadzirwa nemushini.

2. Paunenge uchigadzira konkrete, edza kuchengetedza humwe huwandu hwehupfu hwematombo kuti uwane gradation inonzwisisika, kunyanya kudzora huwandu huri pamusoro pe2.36mm.

3. Pamusoro pekusimbisa kusimba kwekrete, jecha rejecha rinofanira kuchengetedzwa zvakanaka, chikamu chemavara makuru uye maduku chinofanira kuva chinonzwisisika, uye chiyero chemavara maduku chinogona kuwedzerwa zvakakodzera.

4. Muchina wekugeza jecha unonyanya kushandisa flocculant kudonha uye kubvisa dhaka, uye chikamu chikuru che flocculant chicharamba chiri mujecha rakapedzwa. Iyo yakakwira molecular uremu flocculant ine yakanyanya kupesvedzera pamvura inodzikisa mumiririri, uye fluidity uye slump kurasikirwa kwekongiri zvakare yakanyanya kukura kana huwandu hwemusanganiswa hwakapetwa kaviri.

Kufurira kweAdmixture uye Admixture Adaptability pane Concrete Quality

Power plant fly ash yatove shoma, uye milled fly ash inozvarwa. Mabhizinesi ane hana yakanaka achawedzera chimwe chikamu chedota mbishi. Mabhizinesi ane moyo mutema ese ibwe hupfu. Yakakura, chiitiko chacho chiri 50% kusvika 60%. Huwandu hwelimestone hupfu hwakakanyiwa munhunzi dota hauzongokanganisa kurasikirwa nekupisa kwenhunzi madota asiwo kunokanganisa basa rayo.

1. Simbisa kuongororwa kwekukuya madota enhunzi, kubata shanduko yekurasikirwa kwayo pakupisa, uye nyatsoteerera kune reshiyo yemvura inodiwa.

2. Imwe chiyero che clinker inogona kuwedzerwa zvakakodzera kune inokuya nhunzi madota kuti iwedzere basa.

3. Zvinorambidzwa zvachose kushandisa marasha gangue kana shale nezvimwe zvinhu zvine mvura yakanyanya kunyura kukuya madota enhunzi.

4. Humwe huwandu hwezvigadzirwa zvine zvigadziriso zvinoderedza mvura zvinogona kuwedzerwa zvakakodzera kune grinding fly ash, iyo ine imwe mhedzisiro pakudzora kudiwa kwemvura.
