Mlingo ndi kumwa madzi polycaxylate superplastic:

Polycaxtlate SuperPlasticili ndi mawonekedwe a mlingo wotsika ndi kuchepetsa madzi ambiri. Pamene Mlingo ndi 0.15-0.3%, mtengo wochepetsera madzi ungafike mu 18-40%. Komabe, chiwerengero cha madzi ndi chochepa kwambiri (pansipa 0.4), mlingo umakhala wosakhudzika kuposa pomwe chiwerengero cham'madzi ndi chokwera. Kuchepetsa kwamadzi kwaPolycaxtlate SuperPlasticimasiyanasiyana ndi kuchuluka kwa Cemention. Pansi pa mikhalidwe yomweyo, kuchuluka kwa madzi otsika mtengo kwa simential zinthu zosakwana 3 ndizochepera 400kg / m3, ndipo kusiyana kumeneku kumanyalanyazidwa. Komabe, pakugwiritsa ntchito, zidzapezeka kuti njira yodziwika bwino iyi siyoyeneraPolycaxtlate SuperPlastic, makamaka chifukwaPolycaxtlate SuperPlasticali ndi chidwi ndi madzi amadzi kuposa kukhala ndi zikhalidwe zapamwamba. Madzi akamamwa madzi akamachepetsedwa, kugwiritsidwa ntchito kwa konkriti sikungachitike; Madzi akamamwa madziwo ndi okwera, ngakhale kuti malowo amakhala okulirapo, padzakhala magazi ambiri komanso ngakhale tsankho, lomwe limabweretsa zovuta pakuchita konkriti. Izi zimayambitsa zovuta zambiri patsamba lomwelo. Kutentha kumakhala ndi mphamvu kwambiri pa kuchuluka kwaPolycaxtlate SuperPlastic. Pochita izi, zimapezeka kuti kuchuluka kwa kuphatikizika komwe kumagwiritsidwa ntchito popanga masana ndi otsika usiku (kutentha ndikotsika kuposa 15 ℃), ndipo kutsika nthawi zambiri kumachitika "kubwerera ku Big", ngakhale magazi ndi tsankho.

Konkriti ndiosaka kwambiri pa malo ofatsa ndi kumwa madzi kuchepetsa madzi. Zowonjezera zochulukirapo zikapitilira, konkriti imawoneka bwino kwambiri monga tsankho, magazi, osungunuka, kuuma komanso mpweya wambiri.

(1) Kusakanikirana kosakanikirana kuyenera kuchitika kachiwiri ndi zida zosinthidwa kuti zisinthe mlingo kuti mukwaniritse zabwino;

(2) Mlingo waPolycaxtlate SuperPlasticNdipo kumwa kwa konkriti kuyenera kulamulidwa mosamalitsa pakugwiritsidwa ntchito;
