Mhedzisiro yeakanyanya-kugona kwemvura-kuderedza mumiririri pane nyowani kongiri:
①work ~ Kuwedzera yakakwira-kugona kwemvura-kuderedza mumiririri anogona kuwedzera fluidity yekongiri; Iko kutsvedza kwekongiri inowedzera nekuwedzera kwekuwedzera-kugona kwemvura-kuderedza mumiririri. Kana dosage ichisvika 0.75%, iyo yekutsvedza inosvika iyo yakakwira. Kana dosage ichinge ichiwedzera mberi, iyo slump inowedzera, asi kuwedzera kwacho kunowedzera kuva munyoro. Iko kutsvedza kwekongiri kwakawedzerwa neakakwira mvura-yekudzora mumiririri-kuderedza mumiririri nekukurumidza, kazhinji kurasikirwa nekutsvedza mukati meawa imwe, uye yakakura kana tembiricha yakakwira. Kazhinji, iyo yakakodzera dosage yekukasira-kugona kwemvura-kuderedza mumiririri ndeye 0.5% ~ 0.75%. Kana huwandu hwesimu hwakakura, iyo yakakodzera dosage ndeye 0.9% ~ 1.2%. Kubva pane imwe nzvimbo yehupfumi yekuona, iyo inowanzoshandiswa dosage inenge 0.5%.
②Kutadzisa nguva: yakakwira-kugona kwemvura-kuderedza mumiririri ane zvishoma mhedzisiro pane iyo nguva yekugara kongiri. Iyo mhando uye dosage yekubudirira kwemvura-inokonzeresa mumiririri akasiyana, uye huwandu hwesimba hwakasiyana; Mhedzisiro yekubudirira kwemvura-yakakwira-kudzora mumiriri pane yayo kurongeka kwakasiyana mhando dzakasiyana dze cement. Sezvinoratidzwa muTafura 1, nguva yekuisa yeiyo coment yakawedzera neyakanyanya-kugona kwemvura-kuderedza mumiririri.
Kuwedzera: Kuwedzera yakakwira-kugona kwemvura-kuderedza mumiririri kuenda kuConcrete kunogona kuderedza iyo kubuda ropa. Uchishandisa mvura-yekudzora mumiririri nezvinhu zvine chekuita neAF uye AF uye jian-1) zvinogona kuderedza huwandu hwekubuda ropa zvakatowedzera. Kune kongiri yakavhenganiswa neyakajairwa simende, huwandu hwekubuda ropa hwakasanganiswa neFDN, UNF, CRS uye yakaderedzwa mvura ndeye 50% yeiyo 50% yeiyo kongiri.
④AIR Zvemukati: Wedzera mweya wemukati wekongiri. Mhepo yezvinyorwa zveCRS, FDN, uye Unf inowedzera neinenge 1%, kuwedzera kweAF uye Jian-1 iri 0,75%, uye mhepo yezvinyorwa zvekongiri ndeye 5%. Ziva zvakare kuti mhepo yezvinyorwa zvekuyerera kongiri inoderedza kana ichiwedzera yakakwira-kugona kwemvura-kuderedza mumiririri.
⑤heat of hydration: kupisa kwehydration uye perek tembiricha yakasanganiswa neyekubudirira kwemvura-yekudzora mumiririri ari padyo neiyo yeiyo simenti isina kufungidzira, asi nguva yekupisa yekupisa inononoka nemaawa akati wandei. Yakakwira-kugona kwemvura-kuderedza mumiririri anoderedza kupisa kwehydration ye slag sliment. Ona tafura 2 yekupisa kwehydration yeiyo simende yakasanganiswa neyakanyanya-kugona kwemvura-kuderedza mumiririri.
