Nzira yekuziva sei kuwirirana kwemvura-yakasanganiswa masonry mortar?

Iko kuenderana kwekunyorova-yakasanganiswa masonry dhaka kunowanzo kutsanangurwa uchishandisa kuyerera kana kudonha bvunzo, iyo inoyera fluidity kana kushanda kwedhaka. Heino maitiro ekuita bvunzo:

Midziyo Inodiwa:

1. Flow cone kana slump cone
2. Tamping tsvimbo
3. Tepi yekuyeresa
4. Stopwatch
5. Sampuli yedhaka

Maitiro:

Flow Test:

1. Kugadzirira: Ita shuwa kuti kuyerera koni yakachena uye haina zvipingamupinyi. Iise panzvimbo yakati sandara, yakaenzana.
2. Kugadzirira Sample: Gadzirira sampu nyowani yedhaka-yakasanganiswa dhaka zvinoenderana neinodiwa musanganiswa zviyero uye kuenderana zvinodiwa.
3. Kuzadza Koni: Zadza koni inoyerera nesampu yedhaka muzvikamu zvitatu, imwe neimwe ingangoita chikamu chimwe muzvitatu chehurefu hwekoni. Gadzira imwe neimwe layer uchishandisa tamping tsvimbo kuti ubvise chero voids uye uve nechokwadi chekuzadza yunifomu.
4. Kuwedzera Kubvisa: Mushure mekuzadza koni, bvisa dhaka rakawandisa kubva pamusoro pekoni uchishandisa straightedge kana trowel.
5. Kusimudza Koni: Nyatsosimudza kuyerera koni yakatwasuka, kuve nechokwadi kuti hapana lateral kufamba, uye tarisa kuyerera kwedhaka kubva mukoni.
   • Chiyero: Pima chinhambwe chakafambwa nedhaka rinoyerera kubva pasi pekoni kusvika kudhayamita yakapararira uchishandisa tepi yekuyeresa. Nyora kukosha uku sekuyerera kwedhayamita.

Slump Test:

1. Kugadzirira: Ita shuwa kuti slump cone yakachena uye haina chero tsvina. Iise panzvimbo yakati sandara, yakaenzana.
2. Kugadzirira Sample: Gadzirira sampu nyowani yedhaka-yakasanganiswa dhaka zvinoenderana neinodiwa musanganiswa zviyero uye kuenderana zvinodiwa.
3. Kuzadza Koni: Zadza slump cone nesample yedhaka muzvikamu zvitatu, chimwe nechimwe chinenge chikamu chimwe muzvitatu chehurefu hwekoni. Gadzira imwe neimwe layer uchishandisa tamping tsvimbo kuti ubvise chero voids uye uve nechokwadi chekuzadza yunifomu.
4. Kuwedzera Kubvisa: Mushure mekuzadza koni, bvisa dhaka rakawandisa kubva pamusoro pekoni uchishandisa straightedge kana trowel.
5. Subsidence Measurement: Nyatsosimudza koni yakadonha yakatwasuka mukufamba kwakatsetseka, kwakadzikama, zvichiita kuti dhaka ridzikire kana kudonha.
   • Kuyera: Edza mutsauko wehurefu pakati pehurefu hwekutanga hwekoni yedhaka uye kureba kwedhaka rakadonha. Rekodha kukosha uku sekudonha.

Dudziro

• Kuyerera Muedzo: Kuyerera kukuru kwedhayamita kunoratidza kukwirira kwemvura kana kushanda kwedhaka, nepo dhayamita diki rekuyerera richiratidza kuderera kwemvura.
• Slump Test: Kuderera kukuru kunoratidza kushanda kwakanyanya kana kuenderana kwedhaka, nepo kuderera kudiki kukosha kunoratidza kuderera kwekushanda.

Cherechedza:

• Kuenderana kunodiwa kwedhaka remasonry zvinoenderana nezvinodiwa zvechikumbiro, senge rudzi rwemasonry units, nzira yekuvaka, uye mamiriro ekunze. Rongedza chiyero chemusanganiswa uye zvemukati zvemvura zvinoenderana kuti uwane iyo inodiwa kuenderana.
