High-effective water reducer ndi mankhwala admixture kwambiri ntchito konkire mix kapangidwe. Ntchito yake yaikulu ndikuwongolera madzi ndi pulasitiki ya konkire mwa kuchepetsa chiŵerengero cha simenti ya madzi popanda kukhudza mphamvu ndi kukhazikika kwa konkire.
1. Sinthani kuphatikizika kwa konkriti
Kuchepetsa kwamadzi kwapamwamba kwambiri kumapangitsa kuti konkire ikhale yogwirizana komanso imachepetsa porosity pochepetsa kuchuluka kwa madzi osakaniza. Wondiweyani konkire dongosolo angathe kuteteza kulowerera kwa kunja zinthu zoipa (monga madzi, chloride ayoni ndi sulfates, etc.), potero kuwongolera impermeability ndi chisanu kukana konkire. Kulumikizana bwino kungathenso kuchepetsa madzi a pore mkati mwa konkire, kuchepetsa kuthamanga kwa kukula kopangidwa ndi kuzizira kwa madzi a pore panthawi yachisanu ndi mvula ya konkire, potero kuchepetsa kuwonongeka kwa amaundana-thaw.
2. Sinthani kukokoloka kwa mankhwala kukana konkire
High-mwachangu madzi chochepetsera akhoza kusintha kukokoloka kukana mankhwala konkire. Izi zili choncho chifukwa chokhuthala cha konkire chimapangitsa kuti mankhwala owopsa alowe mu konkire, motero amachepetsa kukokoloka kwa mankhwala. Mwachitsanzo, m'malo okhala ndi klorini, kulowetsedwa kwa ayoni a kloridi kumachepa, potero kumatalikitsa nthawi ya dzimbiri lachitsulo ndikuwongolera kukhazikika kwa konkriti yolimba.
3. Sinthani kukana kwa ming'alu ya konkire
Popeza ochepetsetsa kwambiri amadzimadzi amatha kuchepetsa kuchuluka kwa madzi osakaniza, kutsika kwa konkire, makamaka shrinkage ya pulasitiki ndi kuyanika shrinkage, kumachepetsedwa. Kutsika kwapang'onopang'ono kumachepetsa chiopsezo cha konkriti, potero kumapangitsa kuti konkire ikhale yolimba. Kuchepetsa ming'alu ya konkire sikungopindulitsa kokha kukongola ndi kukhulupirika kwa kapangidwe kake, komanso kumachepetsa mwayi wa zinthu zovulaza zakunja zomwe zimalowa mu konkire kupyolera mu ming'alu.
4. Kupititsa patsogolo makina a konkire
High-mwachangu ochepetsera madzi akhoza kwambiri patsogolo mphamvu oyambirira ndi yaitali mphamvu konkire, amene ali ndi zotsatira zofunika pa durability nyumba konkire. Konkire yamphamvu kwambiri imakhala ndi mapindikidwe ochepa pansi pa katundu wanthawi yayitali, kukana bwino kwa ming'alu, ndipo imatha kukana kukokoloka kwa zinthu zachilengedwe. Kuphatikiza apo, kulimba koyambirira kumathandizira kufupikitsa nthawi yochiritsa, kufulumizitsa ntchito yomanga, komanso kuchepetsa ndalama zomanga.
5. Chikoka pa carbonation kuya konkire
Zotsatira za ochepetsera kwambiri madzi pa kuya kwa carbonation konkriti ndizovuta kwambiri. Kumbali imodzi, zochepetsera madzi zimapangitsa kuti konkire ikhale yovuta, zomwe zimapangitsa kuti mpweya woipa wa carbon dioxide ulowetse, motero umachepetsa mpweya wa carbonation; Komano, chifukwa cha mphamvu ya reducers madzi, pangakhale ena incompletely hydrated simenti particles mkati konkire, amene akhoza kutulutsa pores pa ndondomeko kenako hydration, amene akhoza kuonjezera kuya kwa carbonation. Chifukwa chake, m'magwiritsidwe ntchito, ndikofunikira kuganizira mozama zinthu zosiyanasiyana ndikugwiritsa ntchito zochepetsera madzi moyenera.
6. Sinthani chisanu kukana konkire
Zochepetsera bwino kwambiri zamadzi zimatha kusintha kwambiri kukana kwa chisanu kwa konkriti. Izi ndichifukwa choti ochepetsa madzi amachepetsa kuchuluka kwa kusakaniza madzi mu konkire, potero amachepetsa madzi aulere mkati mwa konkire. M'malo otsika kutentha, kuzizira kwa madzi aulere kumapangitsa kuti voliyumu ichuluke, zomwe zimapangitsa kuti konkriti iphwanyike. Kugwiritsa ntchito zida zochepetsera madzi othamanga kwambiri kumachepetsa kuchuluka kwa madzi aulere, motero kumachepetsa kuwonongeka kwa konkire komwe kumachitika chifukwa cha kuzizira kwamadzi.
Zochepetsera madzi zogwira mtima kwambiri zimakulitsa kulimba kwa konkriti mwa kukonza kulimba, kukana kwa dzimbiri, kukana ming'alu ndi kukana chisanu kwa konkriti. Komabe, muzinthu zinazake, zochepetsera madzi ziyenera kusankhidwa moyenera ndikugwiritsidwa ntchito molingana ndi zofunikira zaumisiri ndi momwe chilengedwe chimakhalira kuti chikhale cholimba kwambiri. Panthawi imodzimodziyo, kutsimikizira koyesera koyenera kuyenera kuchitidwa kuti zitsimikizidwe kuti kugwiritsa ntchito madzi ochepetsera madzi kungathandizedi kuti konkire ikhale yolimba.
