Ziziphi izongezo zomeleza udaka?

I-Portland Cement: Njengenxalenye esisiseko yodaka, i-samente yasePortland inegalelo kumandla ayo. I-hydrates ukwenza iikhompawundi ze-cementitious, idibanisa i-aggregates kunye.
Ikalika: Udaka lwesintu luhlala lubandakanya ikalika, ephucula ukusebenza kunye neplastiki. Ikalika ikwanegalelo kwiimpawu zokuziphilisa zodaka kwaye yongeza ukuxhathisa kwayo kwimozulu.

I-Silica Fume: Le mathiriyeli ye-ultrafine, i-byproduct yemveliso ye-silicon yesinyithi, iyasebenza kakhulu kwaye iphucula amandla omdaka kunye nokuqina ngokuzalisa i-voids kunye nokuphucula i-matrix ye-cementitious.
I-Fly Ash: I-byproduct yokutsha kwamalahle, i-fly ash iphucula ukusebenza, inciphisa ukuveliswa kobushushu, kwaye iphakamisa amandla exesha elide kunye nokuqina ngokusabela nge-calcium hydroxide ukwenza iikhompawundi ezongezelelweyo ze-cementitious.

I-Metakaolin: Iveliswa ngodongwe lwe-kaolin calcining kumaqondo obushushu aphezulu, i-metakaolin yi-pozzolan eyongeza amandla odaka, inciphisa ukungeneka, kwaye iphucule ukuqina ngokusabela nge-calcium hydroxide ukwenza imixube eyongezelelweyo yesamente.
Izongezo zePolymer: Iipolymers ezahlukeneyo, ezifana ne-latex, i-acrylics, kunye ne-rabha ye-styrene-butadiene, inokongezwa kwidaka ukuphucula ukunamathela, ukuguquguquka, ukuqina, kunye nokuchasana namanzi kunye neekhemikhali.

I-Cellulose Ether: Ezi zongezo ziphucula ukusebenza, ukugcinwa kwamanzi, kunye nokunamathela kodaka. Bakwanciphisa ukucutheka kunye nokuqhekeka ngelixa bekhulisa ukuqina kunye nokumelana nemijikelo yokunyibilika komkhenkce.
I-Superplasticizers: Ezi zongezo ziphucula ukuhamba komdaka ngaphandle kokunyusa umthamo wamanzi, ukuphucula ukusebenza kunye nokunciphisa imfuno yamanzi angaphezulu, anokuphazamisa amandla.
Abangeneleli boMoya: Ngokudibanisa amaqamza omoya amancinane kudaka, abafakeli bomoya baphucula ukusebenza, ukuxhathisa ukunyibilika komkhenkce, kunye nokuqina ngokuvumela utshintsho lwevolumu olubangelwa kukuguquguquka kobushushu.
I-Calcium Chloride: Ngamanani amancinci, i-calcium chloride ikhawuleza i-hydration ye-samente, ukunciphisa ixesha lokumisela kunye nokuphucula ukuphuhliswa kwamandla kwangaphambili. Nangona kunjalo, ukusetyenziswa ngokugqithisileyo kunokukhokelela ekugxunyekeni kokuqiniswa.

I-Sulfate-based Additives: Ii-Compounds ezifana ne-gypsum okanye i-calcium sulfate inokuphucula ukuxhathisa komdaka ekuhlaselweni kwe-sulfate kunye nokunciphisa ukwanda okubangelwa ukusabela phakathi kwe-ion sulfate kunye nezigaba ze-aluminate kwi-samente.
I-Corrosion Inhibitors: Ezi zongezo zikhusela ukuqiniswa kwentsimbi efakwe kwi-corrosion, ngaloo ndlela igcina imfezeko yesakhiwo kunye nokuphila ixesha elide kwezinto zodaka.
IiPigments eziMbala: Ngelixa udaka lungomelezi ngokuthe ngqo, ii-pigments ezinemibala zingongezwa ukuphucula ubuhle kunye nokumelana ne-UV, ngakumbi kwizicelo zoyilo.
I-Shrinkage Ukunciphisa Izongezo: Ezi zongezo zinciphisa ukuqhekeka kwe-shrinkage ngokunciphisa umthamo wamanzi, ukuqinisa amandla ebhondi, kunye nokulawula izinga lokunyuka kwamanzi ngexesha lokunyanga.
I-Microfibers: Ukubandakanya ii-microfibers, ezifana ne-polypropylene okanye i-glass fibers, iphucula ukuqina komdaka kunye namandla okuguquguquka, ukunciphisa ukuqhekeka kunye nokuphucula ukuqina, ngokukodwa kumacandelo amancinci.

izongezo zidlala indima ebalulekileyo ekwandiseni iipropathi zodaka, kwaye ukukhetha kwazo okunengqiqo nokusetyenziswa kwazo zibalulekile ekufezekiseni amandla afunekayo, ukuqina, kunye neempawu zokusebenza kwizicelo ezahlukeneyo.
