Makhalidwe ake ndi otaniPCE-based admixtures?

Mphamvu zochepetsera madzi kwambiri:Zotengera PCE zosakaniza kuthandizira kuchepetsa madzi polola konkire kuti ikhale yogwira ntchito pamene kuchepetsa kumwa madzi.Izi zimatheka pogwiritsa ntchito simenti yokwera pang'ono ndi zosakaniza zina kuti apange kusakaniza kowuma.

PCE superplasticizers Nthawi zambiri amagwiritsidwa ntchito popanga konkriti kokonzeka komwe kumafunikira magwiridwe antchito apamwamba komanso olimba.

Kukana kwakukulu: Kukaniza kwa admixture kumathandizira konkire kupirira kuukira kwa sulfate, kuwonongeka kwa chisanu ndi ma alkali-silika.

Kusamalira Slump: Monga njira yabwino yochepetsera madzi,Kusakaniza kwa PCE zingathandize kuchepetsa madzi okhutitsidwa kuti tikwaniritse kugwa anapatsidwa mwa kuwongolera workability wa konkire osakaniza.Izi nthawi zambiri zimatheka ndi kuchepetsa chiŵerengero cha madzi-simenti ndi kuonjezera kugawa kwa tinthu.Choncho, izi zimathandiza kupewa madzi ochulukirapo panthawi yosakaniza, zomwe zingayambitse kutaya.

Ubwino waPCE-Based Mixture:

Kuchita bwino:Zotengera PCE zosakaniza perekani zosakaniza za konkriti zogwira mtima kwambiri ndi mphamvu zapamwamba komanso kuthamangitsa kugwira ntchito popanda kusokoneza katundu.Imathandiziranso kugwira ntchito kwa konkriti yatsopano, kupangitsa kuti ikhale yosavuta kupopa ndikuyika.

 Amachepetsa permeability: Admixtures akhoza kuchepetsa permeability konkire, potero kuchepetsa chiopsezo cha chinyezi kudutsa mu konkire.

 Zosakaniza za konkire zapamwamba: Zosakaniza zochokera ku Perchlorethylene zimabweretsa zosakaniza zabwino kwambiri za konkire zokhala ndi simenti yabwino komanso kuthirira katundu.Izi zimakulitsa mphamvu ndi khalidwe la konkire.

 Chepetsani kuchepa: Zosakaniza za konkire zimatha kuchepetsa kuchepa kwa konkire, zomwe zimathandiza kuchepetsa chiopsezo cha kusweka ndi kuwonongeka kwina.Zosakaniza izi zimapereka konkire osakaniza ndi mkati machiritso dongosolo.Kukhalapo kwa ma polycarboxylate ethers kumapangitsa kuti osakaniza azitha kuyamwa ndikusunga madzi mu osakaniza a konkire.

 Kumaliza bwino:Zotengera PCE zosakaniza imatha kukonza konkriti, ndikupangitsa kuti ikhale yosalala, yokongola komanso yowoneka bwino.Kutsirizitsa bwino kumathandiza kuonjezera kukhazikika kwa pamwamba pa konkriti.Kusakaniza kumeneku kumaperekanso mawonekedwe osakanikirana a yunifolomu komanso kumachepetsa chizolowezi cha shrinkage cracking.Kuonjezera apo, zingathandize kuchepetsa kuyamwa kwa madzi ndikuletsa kutuluka kwa madzi.
