Ndezvipi zvinowedzera zvinosimbisa dhaka?

Simende yePortland: Sechinhu chakakosha padhaka, simende yePortland inobatsira pakusimba kwayo. Inonyorovesa mvura kuti igadzire simbi dzinoita simende, ichibatanidza zvinhu zvose pamwe chete.
Lime: Dura rechinyakare rinowanzova nelame, iyo inowedzera kushanda uye plasticity. Lime inobatsirawo mukugadzirisa kwayo dhaka uye inowedzera kuramba kwayo kukanganiswa nemamiriro ekunze.

Silica Fume: Iyi simbi yakanaka kwazvo, inoburitswa nekugadzirwa kwesimbi yesilicon, inoshanda zvakanyanya uye inovandudza simba remortar nekugara kwenguva refu nekuzadza maburi uye kuwedzera simende.
Dota reNhunzi: Rinobva mukupiswa kwemarasha, dota renhunzi rinovandudza kushanda, rinoderedza kupisa, uye rinowedzera simba uye kugara kwenguva refu nekushandisa calcium hydroxide kugadzira mamwe macompounds anosimbisa simende.

Metakaolin: Inogadzirwa nekugadzira ivhu rekaolin pakupisa kwakanyanya, metakaolin ipozzolan inowedzera simba redhaka, inoderedza kupinda kwemvura, uye inovandudza kugara kwenguva refu nekuita calcium hydroxide kuti igadzire mamwe macompounds ecementitious.
Zvimwe Zvinowedzerwa zvePolymer: Mapolymer akasiyana-siyana, akadai selatex, acrylics, uye rabha yestyrene-butadiene, anogona kuwedzerwa mumortar kuti awedzere kunamira, kuchinjika, kuomarara, uye kuramba mvura nemakemikari.

Cellulose Ether: Izvi zvinowedzera simba rekushanda, kuchengetedza mvura, uye kunamira kwedhaka. Zvinoderedzawo kupwanyika nekutsemuka uku zvichiwedzera kugara kwenguva refu uye kuramba kutonhora nekunyunguduka.
Superplasticizers: Izvi zvinowedzera mvura zvinovandudza kufamba kwedhaka pasina kuwedzera huwandu hwemvura, zvichiwedzera kushanda zvakanaka uye zvichideredza kudiwa kwemvura yakawanda, izvo zvinogona kukanganisa simba redhaka.
Zvinopinza Mhepo: Nekuisa mabubble madiki emhepo mudhaka, zvinopinza mhepo zvinovandudza kushanda, kudzivirira kuomarara kwechando, uye kugara kwenguva refu nekugamuchira shanduko dzehuwandu hunokonzerwa nekuchinja-chinja kwetembiricha.
Calcium Chloride: Kana iri shoma, calcium chloride inokurumidza kunyorovesa simende, ichideredza nguva yekuiisa uye inowedzera kukura kwesimba pakutanga. Zvisinei, kushandiswa zvakanyanya kunogona kukonzera ngura yekusimbisa simende.

Zvimwe zvinowedzerwa zvine sulfate: Mishonga yakaita segypsum kana calcium sulfate inogona kuvandudza kusimba kwemortar pakurwiswa nesulfate uye kuderedza kukura kunokonzerwa nekuita pakati pemaion esulfate nealuminate mu simende.
Zvinodzivirira Kuora: Izvi zvinowedzerwa zvinodzivirira simbi yakabatanidzwa kubva mukuora, nokudaro zvichichengetedza kusimba kwechimiro uye kugara kwenguva refu kwezvinhu zvedhaka.
Mavara Akapendwa: Kunyange zvazvo asingasimbise dhaka zvakananga, mavara akapendwa anogona kuwedzerwa kuti awedzere runako uye kuramba UV, kunyanya mukushandiswa kwezvivakwa.
Zvinowedzera Kuderedza Kupwanya: Izvi zvinoderedza kupwanya kwemvura nekuderedza huwandu hwemvura, kuwedzera simba rekubatana, uye kudzora mwero wekubuda kwemvura panguva yekupwanya.
Microfibers: Kuisa microfibers, dzakadai sepolypropylene kana girazi fibers, kunovandudza simba rekudhonza uye kusimba kwemortar, zvichideredza kutsemuka uye kuwedzera kugara kwenguva refu, kunyanya muzvikamu zvitete.

Zvimwe zvinowedzerwa zvinoita basa guru mukusimudzira hunhu hwedhaka, uye kusarudza kwaro nekushandisa kwaro zvine hungwaru kwakakosha pakuwana simba, kugara kwenguva refu, uye hunhu hwekushanda hwaunoda mukushandiswa kwakasiyana-siyana.
