Ndezvipi zvinowedzera zvinosimbisa dhaka?

Portland Cement: Sechinhu chakakosha chedhaka, Portland simende inobatsira pakusimba kwayo. Inoisa mvura kuti igadzire simende makomisheni, ichisunga akaunganidzwa pamwechete.
Lime: Doka rechinyakare rinowanzosanganisira lime, iro rinowedzera kushanda uye purasitiki. Lime inobatsirawo kune dhaka rekuzviporesa uye inowedzera kuramba kwayo kumamiriro ekunze.

Silica Fume: Iyi ultrafine zvinhu, byproduct yesilicon simbi kugadzirwa, inoshanda zvakanyanya uye inovandudza simba rematope uye kusimba nekuzadza voids uye kuwedzera simende matrix.
Fly Ash: A byproduct yekupisa kwemarasha, kubhururuka madota kunonatsiridza kushanda, kunoderedza kupisa chizvarwa, uye kunowedzera simba renguva refu uye kusimba nekuita ne calcium hydroxide kuumba mamwe simende makomisheni.

Metakaolin: Inogadzirwa ne calcining ivhu re kaolin pakudziya kwepamusoro, metakaolin i pozzolan inowedzera simba redhaka, inoderedza kupinza, uye inovandudza kusimba nekuita ne calcium hydroxide kuti igadzire mamwe simende makomisheni.
Polymer Additives: Mapolymer akasiyana-siyana, akadai se latex, acrylics, uye styrene-butadiene rubber, anogona kuwedzerwa mudhaka kuti avandudze kunamatira, kushanduka, kuoma, uye kuramba mvura nemakemikari.

Cellulose Ether: Izvi zvinowedzera zvinovandudza kushanda, kuchengetedza mvura, uye kunamatira kwedhaka. Ivo zvakare vanoderedza shrinkage uye kutsemuka uku vachiwedzera kusimba uye kuramba kune kutonhora-kunyungudika kutenderera.
Superplasticizers: Izvi zvinowedzera zvinovandudza kuyerera kwedhaka pasina kuwedzera mvura yemukati, kuwedzera kushanda uye kuderedza kudiwa kwekuwedzera mvura, izvo zvinogona kukanganisa simba.
Mhepo Vanopinda: Nekuisa tutuburu tudiki mudhaka, zvinopinza mhepo zvinovandudza kushanda, kutonhora-kunyungudika, uye kusimba nekugadzirisa kuchinja kwevhoriyamu kunokonzerwa nekushanduka kwekushisa.
Calcium Chloride: Muzvishoma, calcium chloride inomhanyisa hydration ye simenti, kuderedza nguva yekuisa uye kuwedzera simba rekutanga kukura. Zvisinei, kushandiswa kwakanyanya kunogona kukonzera kuora kwekusimbisa.

Sulfate-based Additives: Mishonga yakafanana negypsum kana calcium sulfate inogona kuvandudza kuramba kwevhu kune sulfate kurwisa uye kuderedza kuwedzera kunokonzerwa nekuita pakati pe sulfate ions uye aluminate phases mu simenti.
Corrosion Inhibitors: Izvi zvinowedzera zvinodzivirira simbi yekusimbisa kubva mukuora, nekudaro kuchengetedza kutendeseka kwechimiro uye hupenyu hurefu hwezvinhu zvedhaka.
Colored Pigments: Kunyange isingasimbise dhaka zvakananga, mavara ane mavara anogona kuwedzerwa kuwedzera aesthetics uye UV kuramba, kunyanya mumashandisirwo ekuvaka.
Shrinkage Reducing Additives: Izvi zvinowedzera kuderedza kupera kwekuputika nekudzikisa mvura, kuwedzera simba rebhondi, uye kudzora chiyero chekubuda panguva yekurapa.
Microfibers: Kubatanidza microfibers, zvakadai sepolypropylene kana girazi fibers, inovandudza kusimba kwedhaka uye flexural simba, kuderedza kuputika uye kuwedzera kusimba, kunyanya muzvikamu zvitete.

zvekuwedzera zvinoita basa rakakosha mukusimudzira zvivakwa zvedhaka, uye kusarudzwa kwavo zvine hungwaru uye kushandisa kwakakosha kuti uwane simba raunoda, kusimba, uye maitiro ekuita mumashandisirwo akasiyana siyana.
