Ndi zowonjezera ziti zomwe zimalimbitsa matope?

Simenti ya Portland: Monga gawo lofunikira la matope, simenti ya Portland imathandizira kulimba kwake. Imanyowetsa madzi kuti ipange zinthu zolimbitsa simenti, zomwe zimalumikiza zinthuzo pamodzi.
Laimu: Dothi lachikhalidwe nthawi zambiri limakhala ndi laimu, zomwe zimapangitsa kuti ntchito ikhale yosavuta komanso yolimba. Laimu imathandizanso kuti dothi lizidzichiritsa lokha komanso limawonjezera kukana kwake kuzizira.

Fume ya Silika: Chipangizochi chopangidwa ndi chitsulo cha silicon, chimagwira ntchito bwino kwambiri ndipo chimalimbitsa mphamvu ya matope ndi kulimba kwawo podzaza mabowo ndikuwonjezera simenti.
Phulusa la Ntchentche: Phulusa la ntchentche limapangidwa kuchokera ku kuyaka kwa malasha, limathandiza kuti ligwire ntchito mosavuta, limachepetsa kutentha, komanso limalimbitsa mphamvu ndi kulimba kwa nthawi yayitali pochita zinthu ndi calcium hydroxide kuti apange zinthu zina zolimbitsa simenti.

Metakaolin: Yopangidwa ndi dongo la kaolin lomwe limasungunuka kutentha kwambiri, metakaolin ndi pozzolan yomwe imawonjezera mphamvu ya matope, imachepetsa kulowa kwa madzi, komanso imalimbitsa kulimba mwa kuchitapo kanthu ndi calcium hydroxide kuti ipange mankhwala ena owonjezera a simenti.
Zowonjezera za Polima: Ma polima osiyanasiyana, monga latex, acrylics, ndi rabara ya styrene-butadiene, amatha kuwonjezeredwa ku matope kuti akonze kumatirira, kusinthasintha, kulimba, komanso kukana madzi ndi mankhwala.

Cellulose EtherZowonjezera izi zimathandiza kuti matope azigwira ntchito bwino, kusunga madzi, komanso kumamatira bwino. Zimathandizanso kuchepetsa kusweka ndi ming'alu pamene zikulimbitsa kulimba komanso kukana kuzizira ndi kusungunuka.
Superplasticizers: Zowonjezera izi zimapangitsa kuti matope aziyenda bwino popanda kuwonjezera kuchuluka kwa madzi, zomwe zimathandiza kuti madzi azigwira ntchito bwino komanso kuchepetsa kufunika kwa madzi owonjezera, zomwe zingawononge mphamvu.
Zipangizo Zopumira Mpweya: Mwa kuyika thovu laling'ono la mpweya mu matope, zipangizo zopumira mpweya zimathandiza kuti ntchito ikhale yosavuta, kukana kuzizira ndi kusungunuka, komanso kulimba mwa kupirira kusintha kwa voliyumu komwe kumachitika chifukwa cha kusinthasintha kwa kutentha.
Calcium Chloride: Kawirikawiri, calcium chloride imafulumizitsa madzi a simenti, kuchepetsa nthawi yokhazikika komanso kukulitsa mphamvu yoyambirira. Komabe, kugwiritsa ntchito mopitirira muyeso kungayambitse dzimbiri la mphamvu yolimbitsa.

Zowonjezera Zochokera ku Sulfate: Ma compounds monga gypsum kapena calcium sulfate amatha kupititsa patsogolo kukana kwa matope ku sulfate ndikuchepetsa kukula komwe kumachitika chifukwa cha momwe ma ion a sulfate ndi magawo a aluminate amagwirira ntchito mu simenti.
Zoletsa Kutupa: Zowonjezera izi zimateteza chitsulo cholimba kuti chisawonongeke, motero zimasunga umphumphu wa kapangidwe kake komanso kukhala ndi moyo wautali wa zinthu za matope.
Utoto Wofiirira: Ngakhale kuti suli wolimbitsa matope mwachindunji, utoto wofiirira ukhoza kuwonjezeredwa kuti uwonjezere kukongola ndi kukana kwa UV, makamaka pa ntchito zomangamanga.
Zowonjezera Zochepetsa Kuchepa kwa Madzi: Zowonjezerazi zimachepetsa kusweka kwa madzi mwa kuchepetsa kuchuluka kwa madzi, kulimbitsa mphamvu ya ma bond, komanso kuwongolera kuchuluka kwa nthunzi panthawi yowuma.
Ulusi Waung'ono: Kuphatikiza ulusi waung'ono, monga polypropylene kapena ulusi wagalasi, kumawonjezera mphamvu ya matope yokoka ndi kusinthasintha, kuchepetsa ming'alu ndikuwonjezera kulimba, makamaka m'magawo oonda.

Zowonjezera zimagwira ntchito yofunika kwambiri pakukweza mphamvu za matope, ndipo kusankha ndi kugwiritsa ntchito kwawo mwanzeru ndikofunikira kuti pakhale mphamvu, kulimba, komanso magwiridwe antchito omwe amafunidwa pakugwiritsa ntchito kosiyanasiyana.
