Chii Chinonzi Doka?

Mortar imhando yezvivakwa zvekuvaka zvinoshandiswa sechibatiso kana chinonamira mukuvaka masonry. Icho chinhu chakaita sepaste chinoumbwa nemusanganiswa wezvinhu, kazhinji zvinosanganisira simende, lime, jecha, uye mvura. Doka rinoiswa pakati pezvidhinha, matombo, kana mamwe masonry units kuti zvisunge pamwe chete uye kugadzira chimiro chakasimba uye chakasimba.

Heano zvimwe zvakakosha zvinoumba dhaka:

1. Simende: Portland simende ndiyo inonyanya kushandiswa mhando yesamende inoshandiswa mudhaka. Inoshanda sechisungiriro, ichibata zvimwe zvinhu pamwe chete uye ichipa simba kudhaka kana yaoma. Mhando uye chikamu chesimende chinoshandiswa chinogona kukanganisa zvinhu zvedhaka, zvakadai sesimba rayo uye nguva yekuisa.
2. Lime: Lime inowanzowedzerwa mudhaka kuti ivandudze kushanda kwayo, purasitiki, uye kusimba. Inogona zvakare kusimbisa chisungo pakati pedhaka uye masonry unit. Hydrated lime ndiyo inonyanya kushandiswa mhando yeraimu mumatope ekugadzira.
3. Jecha: Jecha ndiyo yekutanga aggregate mudhaka, inopa huwandu uye kuzadza voids pakati pemasonry unit. Kukura uye rudzi rwejecha rinoshandiswa zvinogona kukanganisa kushanda, kusimba, uye kutaridzika kwedhaka. Majecha akatsetseka anogadzira dhaka rakatsetseka, nepo jecha rakakora richigona kuwedzera simba.
4. Mvura: Mvura yakakosha kune hydration ye simenti uye lime mumusanganiswa wedhaka. Inoshanda senge svikiro rekuita kwemakemikari, zvichiita kuti simiti irape nekuoma. Kuwanda kwemvura yakawedzerwa kumusanganiswa wedhaka kunokanganisa kuwirirana kwayo, kushanda, uye nguva yekuisa.

Mortar inoshanda akati wandei akakosha mabasa mukuvaka masonry:

• Bonding: Doka rinosunga masonry units pamwechete, kugadzira chimiro chakabatana chinogona kumira mitoro uye kushushikana.
• Kutakurwa Kwemutoro: Doka rinogovera mutoro kubva kune imwe masonry unit kuenda kune imwe, kuve nechokwadi kugadzikana uye kurongeka kwechimiro.
• Kudzivirira mvura: Doka rinobatsira kuvhara majoini pakati pemasonry unit, kudzivirira kupinza kwemvura uye kudzivirira chivakwa kubva pakukuvadzwa kwemwando.
• Aesthetic Finish: Doka rinogonawo kubatsira pakuonekwa kwechimiro chemasoni, chine mavara akasiyana uye maumbirwo anowanikwa kuti awane anodiwa maitiro.

Pakazere, dhaka chinhu chakakosha pakuvaka masonry, ichipa simba, kusimba, uye kugadzikana kune akasiyana marudzi ezvivakwa, kubva kumadziro uye zvivakwa kusvika kumabhiriji uye zvivakwa.
