1. Sayansi Yazinthu ndi Njira Zogwirira Ntchito
1.1 Tanthauzo ndi Gulu la Zosakaniza Zopepuka
(Zosakaniza za Concrete zopepuka)
Zosakaniza zopepuka za konkriti ndizinthu zapadera zamankhwala kapena zakuthupi zomwe zimapangidwira kuti zichepetse kuchuluka kwa makina a simenti pomwe zimasunga kapena kukonza magwiridwe antchito komanso othandiza..
Mosiyana miyambo aggregates, zophatikizika izi zimapereka porosity yoyendetsedwa kapena kuphatikiza magawo otsika kwambiri mu matrix a konkriti., kumabweretsa kulemera kwa chipangizo nthawi zambiri kuyambira 800 ku 1800 kg/m AWIRI, kusiyana ndi 2300– 2500 kg/m³ kwa konkire wamba.
Iwo amagawidwa mokulira mu mitundu iwiri: mankhwala otulutsa thovu ndi zophatikizika zopepuka zopepuka.
Oimira mankhwala frothing amapanga zabwino, mpweya wokhazikika kudzera mu in-situ gas– nthawi zambiri kudzera mu aluminiyamu ufa mu konkriti yopangidwa ndi aerated autoclaved (AAC) kapena hydrogen peroxide yokhala ndi chothandizira– pomwe ma inclusions opangidwa kale amakhala ndi polystyrene yowonjezera (EPS) mbewu, perlite, vermiculite, ndi dzenje za ceramic kapena polymer microspheres.
Zosintha zapamwamba zimaphatikizanso nanostructured permeable silica, aerogels, ndi zowunjikanso zopepuka zopepuka zochokera kuzinthu zopangidwa ndi mafakitale monga magalasi owonjezera kapena slag.
Kusankha admixture zimadalira chofunika matenthedwe kutchinjiriza, mphamvu, kukana moto, ndi ntchito, kuwapangitsa kukhala osinthasintha pazofunikira zosiyanasiyana zomanga.
1.2 Kapangidwe ka Pore ndi Kachulukidwe-Katundu Ubale
Kuchita bwino kwa konkire yopepuka kumayendetsedwa ndi morphology, kugawa kukula, ndi interconnectivity wa pores anayambitsa ndi admixture.
Machitidwe abwino amaphatikizapo kufalikira mofanana, ma pores otsekedwa ndi kukula pakati 50 ndi 500 ma micrometer, zomwe zimachepetsa kuyamwa kwamadzi ndi matenthedwe matenthedwe pomwe zimagwiritsa ntchito mwayi wotsekera.
Tsegulani kapena olumikizidwa pores, pamene kuchepetsa kachulukidwe, imatha kusokoneza mphamvu ndi kukhazikika pothandizira kupeza chinyontho komanso kuwonongeka kwa chisanu.
Zosakaniza zomwe zimakhazikika bwino, olekanitsidwa thovu– monga zopangira mapuloteni kapena zopangira zopangira konkriti ya thovu– onjezerani kukhazikika kwa makina komanso kutentha kwabwino.
Mgwirizano wosiyana pakati pa kachulukidwe ndi kulimba kolimba kwakhazikitsidwa bwino; komabe, makono admixture formulations amachepetsa malondawa kudzera mu matrix densification, fiber reinforcement, ndi optimized machiritso regimens.

Mwachitsanzo, kuphatikiza phulusa la silika kapena phulusa la ntchentche pamodzi ndi zoyimira zotulutsa thovu zimakonza pore chimango ndikuwonjezera phala la konkire., kupangitsa konkriti yamphamvu kwambiri yopepuka (mpaka 40 MPa) kwa ntchito zomanga.
2. Key Admixture Type ndi Maudindo Awo Aukadaulo
2.1 Ma Broker Ochita thovu ndi Mayankho Opatsira Air-Entraining
Oyimira mapuloteni komanso opangira thovu ndiye maziko a kupanga konkire ya thovu, kupanga thovu lotetezeka la mpweya lomwe limalumikizidwa mwamakina mu slurry ya konkriti.
Zakudya zomanga thupi zama protein, zochokera ku nyama kapena zamasamba, amapereka chitetezo chokwanira cha thovu ndipo ndi abwino kwa mapulogalamu otsika kwambiri (
Cabr-Concrete ndi ogulitsa Concrete Admixture yokhala ndi over 12 zaka zambiri zachitetezo cha nano-building energy komanso chitukuko cha nanotechnology. Imavomereza kulipira kudzera pa Kirediti kadi, T/T, West Union ndi Paypal. TRUNNANO idzatumiza katundu kwa makasitomala akunja kudzera ku FedEx, DHL, ndi mpweya, kapena panyanja. Ngati mukuyang'ana Concrete Admixture yapamwamba kwambiri, chonde omasuka kulankhula nafe ndi kutumiza kufunsa.

Zolemba ndi zithunzi zonse zachokera pa intaneti. Ngati pali zovuta za kukopera, chonde titumizireni mu nthawi kuti muchotse.
