Admumture anoreva kirasi yezvinhu izvo zvinogona kubatsira zvakanyanya kana zvimwe zvivakwa zvekongiri. Zvemukati zvayo zvinowanzo maakaunzi chete pane zvisingasviki 5% yeiyo simenti yezvinyorwa, asi inogona kuvandudza zvakanyanya kugona, simba, kusimba kwekongiri kana kugadzirisa nguva yekugara uye kuchengetedza simende.
1. Kugadziriswa kweAdmixture:
Concrete Admixture inowanzo kuve yakadzama maererano nemabasa avo makuru:
a. Admixtures yekuvandudza iyo rheological zvivakwa zvekongiri. Iko kune kunyanya mvura kuderedza mumiriri, mhepo inopinda mumiririri, kupomba mumiririri uye zvichingodaro.
b. Admixture yekugadzirisa mamiriro uye kuomesa zvivakwa zvekongiri. Kune vanonyanya kudzoreredza, vanowedzera, vekutanga masimba masimba, nezvimwe.
c. Admixture yekugadzirisa mhepo yezvinyorwa zvekongiri. Iko kune kunyanya mhepo-yekupindira vamiririri, mhepo-yekupindira vamiririri, vaenzi vanopikisa, nezvimwe.
d. Admixture kuti uvandudze concrete kusimba. Iko kune kunyanya mhepo-inopinda mumhepo, vamiririri vemvura, ngura inthbitors uye zvichingodaro.
e. Admixture inopa zvakakosha zvivakwa zvekongiri. Iko kune kunyanya antifreeze, kuwedzera mumiririri, colant, mhepo-inopinda mumiririri uye kupomba mumiririri.
2. Inowanzo shandiswa sewakakura
Mvura kuderedza mumiririri kunoreva kushamwaridzana kunogona kuderedza kusanganisa kwemvura mumamiriro akafanana ekongiri; Kana kuti inogona kuwedzera concrete slump kana iyo kongiri musanganiswa chiyero uye kushandiswa kwemvura kunoramba kuchisikwa. Zvinoenderana nehukuru hwemvura kuderedza mwero kana kuwedzera kwekutsvedza, zvakakamurwa kuita zvikamu zviviri: zvakajairika mvura kudzora mumiririri uye yakanyanya kunaka mvura kudzora mumiririri.
Uyezve, pane gadziriro yemvura-inoderedza mvura, yakadai seyemhepo-yekupandukira mvura-kudzora vamiriri, iyo ine mvura-yekudzora mvura uye inokonzerwa nemhepo-inokonzeresa simba; Mvura zhinji-yekudzora mvura-inoderedza vamiririri vane mvura-inoderedza uye kutanga-simba - kugadzirisa mhedzisiro; Mvura kuderedza mumiririri, zvakare ine basa rekunonoka kuronga nguva uye zvichingodaro.
Basa guru rekubhadhara mvura:
a. Zvakanyanya kuvandudza fluidity nemusanganiswa mumwechete wachi.
b. Kana iyo fluity uye simende isina kushandurwa, kuderedza mvura yemvura, kuderedza mvura yemvura, uye kuwedzera simba.
c. Kana iyo nzira nesimba uye simba rirambe isina kuchinjika, kushandiswa kweiyo yekemende kunoponeswa uye mutengo wacho wadzikira.
d. Kuvandudza basa rekushanda kongiri
e. Kuvandudza kujaira kwekongiri
f. Gadzirira kumusoro-simba uye yakakwirira-performance kongiri.
Polysulfonate Series: Kusanganisira naphthalene Sulfonate Formaldehyde Condenste (NSF), P-AMINEBENCE Sulfondenate, Polystyrene Sulfonates uye Sulfonated Ketone Aldehyde resins, etc. Semuenzaniso, yedu inowanzoshandiswa FDN ndeye naphthalene sulfonate formaldehyde condenstehdehyde condensya.
Polyarcarboxylate Series: Zvinoshanda zvakanaka kudzora yekutanga hydration maitiro uye kuderedza kurasikirwa kwekutsvedza kwekongiri.
Musiyano uripo pakati pekunyanyisa-kugona kwemvura-kuderedza mumiririri-kudzora mumiririri anonyatsoratidzwa mumugodhi wemvura yakakwira-kudzikisira kunogona kuenderera mberi nekuwedzera kwakakura, kana kuenderera mberi kuderedza kudiwa kwemvura. Iyo inoshanda inoshanda yemvura yakajairika inodzikisa idiki.
Mhedzisiro yemukuru wepamusoro pane imwe diki dosage haigone kushandiswa sehwaro hwekutonga mashandiro emukuru weyekuita. Izvi zvinofanirwa kuitirwa kana uchisarudza kuderedza mvura. Iyo yakasarudzika dosage yemukuru yekukwenenzvera inofanirwa kutsanangurwa kuburikidza nekuedzwa, uye hazvifanirwe kushandiswa chete maererano neiyo dosage yemugadziri wepamoyo.
