Kushandiswa Kwemvura Inoderedza, Retarders, uye Superplasticizers

Zvinoderedza mvura, zvinodzoreredza, uye superplasticizers makemikari admixtures anoshandiswa mukatikongiri misanganiswakukwidziridza zvivakwa uye kugadzirisa mashandiro ekongiri panguva yayo nyowani uye yakaoma nyika.Imwe neimwe yeiyi musanganiswa inoshanda chinangwa chakasarudzika, uye inowanzoshandiswa mumapurojekiti ekuvaka kuti uwane inodiwa kongiri hunhu.Ngationgororei mashandisirwo ezvidzikisira mvura, zvidzoreso, uye superplasticizers mune zvakadzama:

1. Zvinoderedza Mvura:

Chinangwa:

• Kuderedza Mvura Yemvura: Mvura inoderedza mvura, inozivikanwawo sevashandi vanoderedza mvura kana kuti plasticizers, inoshandiswa kuderedza kuwanda kwemvura inodiwa mumusanganiswa wekongiri pasina kukanganisa kushanda kwayo.

Mabhenefiti Akakosha:

• Kuvandudza Kushanda Kwekushanda: Nekuderedza mvura yemvura, kuderedza mvura kunovandudza kushanda uye kubatana kwekongiri musanganiswa.
• Kuwedzera Simba: Kudzikiswa kwemvura kunowanzo tungamira kune yakakwirira kongiri simba uye kusimba.
• Kuwedzeredzwa Kupedzwa: Kongiri ine zvinoderedza mvura inowanzova nyore kupedzisa, zvichikonzera nzvimbo yakatsetseka.

Applications:

• Yakakwirira-Simba Concrete: Mvura inoderedza inowanzoshandiswa mukugadzirwa kwekongiri yakakwirira-yakasimba uko kuderera kwemvura-simende ratios inokosha.
• Pumping Concrete: Vanofambisa kupomba kwekongiri pamusoro pemadaro marefu nekuchengetedza kuwedzera kwemvura.

2. Retarders:

Chinangwa:

• Kunonoka Kuisa Nguva: Retarders ma admixtures akagadzirirwa kudzikamisa nguva yekumisikidza kongiri, zvichibvumira nguva yakawedzerwa yekushanda.

Mabhenefiti Akakosha:

• Kuwedzerwa Kushanda Kwekushanda: Vadzori vanodzivirira kugadzika kwekongiri nguva isati yakwana, ichipa nguva yakawanda yekusanganisa, kutakura, nekuisa zvinhu.
• Yakaderedzwa Kutsemuka: Kunonoka kuseta nguva kunogona kuderedza njodzi yekutsemuka, kunyanya mumamiriro ekunze anopisa.

Applications:

• Kupisa Kwemamiriro ekunze Concreting: Mumamiriro ezvinhu apo tembiricha yakakwira inogona kukurumidzira kusetwa kwekongiri, vadzori vanobatsira kubata nguva yekumisikidza.
• MaProjekti Makuru Ekuvaka: Kumapurojekiti makuru uko kutakurwa uye kuiswa kwekongiri kunotora nguva yakareba.

3. Superplasticizers:

Chinangwa:

• Kuvandudza Kushanda Kwekushanda: Superplasticizers, inozivikanwawo seyakakwirira-renji inoderedza mvura, inoshandiswa kuwedzera zvakanyanya kushanda kwekongiri pasina kuwedzera mvura.

Mabhenefiti Akakosha:

• Kushanda Kwepamusoro: Superplasticizers inobvumira kugadzirwa kwekongiri inoshanda uye inoyerera ine yakaderera mvura-simende reshiyo.
• Kuwedzera Simba: Sezvinodzikisira mvura, superplasticizers inobatsira kune yakakwira kongiri simba nekugonesa yakaderera mvura-simende ratios.

Applications:

• Self-Compacting Concrete (SCC): Superplasticizers inowanzoshandiswa mukugadzirwa kweSCC, uko kuyerera kwakanyanya uye kuzvidzora zvivakwa zvinodiwa.
• High-Performance Concrete: Muzvishandiso zvinoda simba repamusoro, kusimba, uye kuderedzwa permeability.

Zvinowanzofungwa:

1. Kugarisana: Admixtures inofanirwa kuenderana nezvimwe zvinhu mumusanganiswa wekongiri, kusanganisira simende, aggregates, uye zvimwe zvinowedzera.
2. Dosage Kudzora: Kunyatso kudzora kweiyo admixture dosage kwakakosha kuti uwane inodiwa kongiri zvivakwa.Kushandisa zvakanyanya kunogona kutungamirira kumigumisiro yakaipa.
3. Kuedza: Kugara uchiyedzwa uye nhanho dzekudzora mhando dzakakosha kuti ive nechokwadi chekushanda kweiyo admixtures mune chaiyo kongiri musanganiswa.
4. Kurudziro yeVagadziri: Kutevedzera kurudziro uye nhungamiro inopihwa nemugadziri wemusanganiswa kwakakosha pakuita kwakaringana.

Mukupedzisa, kushandiswa kwezvinoderedza mvura, zvidzoreso, uye superplasticizers mumisanganiswa yekongiri inopa huwandu hwemabhenefiti, kubva pakuvandudzwa kwekushanda uye nekuwedzera nguva yekuseta kusvika kusimba rakawedzerwa uye kusimba.Kunzwisisa zvinodikanwa chaizvo zvepurojekiti yekuvaka uye kusarudza iyo yakakodzera musanganiswa kana musanganiswa wemisanganiswa kwakakosha pakuzadzisa inodiwa kongiri zvivakwa.Admixture dosages uye kongiri musanganiswa dhizaini inofanirwa kunyatso kurongwa uye kuyedzwa kuti ive nechokwadi chekuita kwakakwana uye kusimba kwenguva refu kwekongiri.
