Superplasticizer yogwira ntchito kwambiri yoyimiridwa ndi polycarboxylate superplasticizer ili ndi zabwino zomwe zimakhala zotsika, kuchepetsa kuchuluka kwa madzi, kusungika bwino kwa kutsika komanso kuchepa pang'ono, ndipo superplasticizer ya polycarboxylate superplasticizer imakhala ndi zoyambitsa zina, zomwe zimapangitsa kusungunuka, kukana chisanu ndi kusunga madzi. konkriti bwino kuposa superplasticizer yachikhalidwe. Chifukwa cha mitundu yosiyanasiyana ya kaphatikizidwe ka polycarboxylate superplasticizer, mtundu wa opanga osiyanasiyana ndi wosiyana kwambiri, kuphatikiza ndi kupanga, chifukwa cha kusinthasintha kwa zopangira zopangira konkriti, kusintha kwamadzi mumchenga, zolakwika za dongosolo muyeso ndi zifukwa zina, chifukwa mu kusakhazikika ntchito konkire mix (zosavuta kupatukana kapena kugwa imfa mofulumira kwambiri) mu ndondomeko yomanga wa polycarboxylate superplasticizer. Sitingathe ngakhale kukwaniritsa zofunikira zomanga. Momwe mungasankhire ma polycarboxylate superplasticizer omwe ndi osavuta kuwongolera komanso osavuta kupanga okhazikika ndi chimodzi mwazinthu zofunika kwambiri kuti mukwaniritse bwino konkriti.
Posankha polycarboxylate superplasticizer kuwonjezera pa mayeso oyambira, monga olimba, kuchuluka kwa madzi, kusungika kwadontho ndi mayeso ena ochita, kukhudzika kwa polycarboxylate superplasticizer kuyenera kuyesedwa kuti aunike mozama za polycarboxylate superplasticizer.
(1) Kuzindikira kukhudzika kwa kusintha kwa mlingo
Sinthani mayeso konkire kusakaniza chiŵerengero ndi chikhalidwe kuti workability ndi kugwa posungira konkire kusakaniza kukumana zofunika, kusunga mlingo wa zipangizo zina zopangira konkire osasintha, kuwonjezera kapena kuchepetsa kuchuluka kwa admixture ndi 0,1% kapena 0,2% motero, ndi kuzindikira kutsika ndi kukulitsa konkriti motsatana. Zing'onozing'ono kusiyana pakati pa mtengo woyezera ndi chiŵerengero choyambirira chosakanikirana, chochepa kwambiri ndi kusintha kwa kuchuluka kwa kusakaniza. Zimasonyezedwa kuti wothandizira kuchepetsa madzi ali ndi chidziwitso chabwino pa mlingo. Cholinga cha kudziwika uku ndikuletsa kuti dziko la konkire lisamasinthe mwadzidzidzi chifukwa cha zolakwika za dongosolo la kuyeza.
(2) Kuzindikira kukhudzika kwa kusintha kwa madzi
Mofananamo, kutengera chiŵerengero chosakanikirana cha konkire kusakaniza pamene chikugwirizana ndi zofunikira, kuchuluka kwa zipangizo zina sikunasinthe, ndipo kumwa madzi a konkire kumawonjezeka kapena kuchepetsedwa ndi 5-8kg / cubic mita motero, ndiko kuti, kusinthasintha kwa madzi. Mchenga wamadzi amchenga umayerekezedwa ndi 1%, ndipo kutsika ndi kufalikira kwa kusakaniza konkire kumayesedwa motsatana. Kusiyana kochepa pakati pa kusakaniza konkire ndi chiŵerengero choyambirira cha kusakaniza, kumapangitsanso chidwi cha madzi ochepetsera madzi. Ngati kusintha kwa madzi kulibe vuto, kungakhale kosavuta kulamulira kupanga.
(3) Yesani kusinthasintha kwa zopangira
Sungani chiŵerengero choyambirira chosakanikirana sichinasinthidwe, m'malo mwa zipangizo zopangira konkriti, motsatira kuyesa kugwa ndi kusintha kowonjezereka kwa kusakaniza konkire pambuyo pa kusintha, ndikuwunika chilengedwe chonse cha kusinthika kwa zipangizo.
(4) Kusintha kwa kutentha
Pitirizani kusakaniza chiŵerengero zofunika zosasinthika, motero kuyesa kusintha kwa kugwa ndi kukulitsa konkire kusakaniza pambuyo kusintha, kupenda chilengedwe cha kutengera kwa zipangizo.
(5) Sinthani mlingo wa mchenga
Wonjezerani kapena kuchepetsa mlingo wa mchenga ndi 1%, yang'anani mkhalidwe wa kusakaniza konkire, fufuzani kusinthasintha kwa mchenga ndi miyala, komanso ngati dziko la konkire lasintha kwambiri.
