Concrete: An Uitimate Guide kune Anotanga

Concrete chinhu chakasiyana-siyana uye chakasimba chinoshandiswa mune dzakasiyana siyana dzekuvaka.Kunyangwe iwe uri DIY anofarira kana nyanzvi yekuvaka, zvakakosha kuti uve nekunzwisisa kwakanaka kwekongiri uye zvimiro zvayo.Mugwaro rino rekupedzisira revanotanga, tichakurukura zvese zvaunoda kuziva nezvekongiri, kusanganisira kuti chii, inogadzirwa sei, mhando dzekongiri, uye basa re cellulose ether mukongiri.

Chii chinonzi Concrete?

Kongiri musanganiswa wesimende, mvura, zviunganidzo (sejecha, matombo, kana dombo rakapwanyika), uye zvakasiyana-siyana zvinowedzera makemikari.Kana zvinhu izvi zvakasanganiswa pamwe chete, kemikari inoitika, zvichiita kuti zvive zvakaoma uye zvakasimba.Kusimba uye kusimba kwekongiri kunoenderana nemhando uye zvikamu zvezvigadzirwa zvinoshandiswa.

Konkrete Inogadzirwa Sei?

Nzira yekugadzira kongiri inosanganisira matanho akawanda.Danho rekutanga nderekusanganisa simende, mvura, uye zviunganidzwa muzvikamu zvakaringana kuti ugadzire paste.Iyo paste inoiswa muforoma kana formwork uye inobvumirwa kuomesa kana kurapa.Kana kongiri yapora, mold kana formwork inobviswa, uye kongiri yakagadzirira kushandiswa.

Mhando dzeConcrete:

Kune akati wandei marudzi ekongiri, imwe neimwe ine zvimiro zvayo zvakasiyana uye mashandisirwo.Mamwe emhando dzakajairika dzekongiri ndeaya:

1. Normal Strength Concrete: Yakajairika simba kongiri ndiyo yakajairika mhando yekongiri inoshandiswa mukuvaka.Iyo ine simba rekumanikidza re2500-5000 psi.
2. High Strength Concrete: Yakakwirira simba kongiri inoshandiswa mumashandisirwo panodiwa simba repamusoro.Iine simba rekumanikidza re10,000-20,000 psi.
3. Lightweight Concrete: Yakareruka kongiri inoshandiswa mumashandisirwo apo huremu hunonetsa.Iyo inogadzirwa uchishandisa lightweight aggregates akadai yakawedzera shale, ivhu, kana slate.
4. Self-Compacting Concrete: Self-compacting kongiri imhando yakasarudzika yekongiri inoyerera uye inobata pachayo, pasina kudiwa kwekuzunguza.
5. Fiber-Reinforced Concrete: Fiber-reinforced concrete imhando yekongiri inosimbiswa nefibers, yakadai sesimbi, girazi, kana mafibhi ekugadzira, kuvandudza zvinhu zvayo.

Basa reSelulosi Ether muKongiri:

Cellulose ether ikemikari inowedzera iyo inowanzoshandiswa mukrete kuti ivandudze maitiro ayo.Iyo polymer inonyungudika nemvura inogona kuwedzerwa kumusanganiswa wekongiri kuti uwedzere kushanda kwayo, kuderedza kunyura kwemvura, uye kuwedzera simba uye kusimba kwayo.

Dzimwe nzira idzo cellulose ether inogona kuvandudza zvimiro zvekongiri ndeidzi:

1. Kuvandudzwa Kwekushanda: Cellulose ether inogona kuvandudza kushanda kwekongiri musanganiswa, zvichiita kuti zvive nyore kuisa uye kupedza.
2. Yakaderedzwa Kunyura kweMvura: Cellulose ether inogona kuderedza huwandu hwemvura inobatwa nekongiri, ichiita kuti irambe ichidzivirira kutonhora-kunyungudika kutenderera uye kuderedza njodzi yekutsemuka.
3. Kuwedzera Simba uye Kugara Kwesimba: Cellulose ether inogona kuwedzera simba uye kusimba kwekongiri, ichivandudza kuramba kwayo kune abrasion, kukanganisa, uye kurwisa kwemakemikari.
4. Enhanced Adhesion: Cellulose ether inogona kuwedzera kunamatira kwekongiri kune dzimwe nzvimbo, kuvandudza kusimba kwayo kwechisungo uye kuderedza njodzi yedelamination.

Mhedziso:

Mukupedzisa, kongiri chinhu chinobatika uye chakasimba chinoshandiswa mumhando dzakasiyana siyana dzekuvaka.Kunzwisisa zvimiro zvekongiri uye basa re cellulose ether mukuita kwayo kwakakosha kune chero munhu anoshanda nekongiri.Nekusarudza mhando chaiyo yekongiri uye nekubatanidza cellulose ether mumusanganiswa, unogona kuvandudza kushanda, kusimba, uye kusimba kwezvivakwa zvako zvekongiri.
