Nzira yekuziva sei kuwirirana kwemvura-yakasanganiswa masonry mortar?

Masonry dhaka chinhu chakakosha mukuvaka, sezvo inosunga zvidhinha kana matombo pamwechete kugadzira yakagadzikana uye yakasimba chimiro. Kuenderana kwekunyorova-yakasanganiswa masonry dhaka kwakakosha kuve nechokwadi chemhando uye kusimba kwechigadzirwa chakapedzwa. Consistency inoreva mwero wekunyorova kana kuoma kwedhaka, izvo zvinokanganisa kushanda kwayo uye kunamatira zvinhu. Muchikamu chino, tichakurukura maitiro ekuona kuwirirana kwemvura-yakasanganiswa masonry mortar uye nei zvakakosha.

Sei Consistency Yakakosha muMasonry Mortar?

Kuenderana kwemasonry dhaka kwakakosha nekuda kwezvikonzero zvinoverengeka:

1. Kushanda: Kusawirirana kwedhaka kunokanganisa kushanda kwayo, izvo zvinoreva kuti zviri nyore sei kuparadzira uye kuumba dhaka. Kana dhaka racho rakaoma zvakanyanya, richava rakaoma kupararira uye harina kumira zvakanaka pazvidhinha kana matombo. Kana yakanyanya kunyorova, inomhanya zvakanyanya uye inogona kusabata chimiro chayo.

2. Kunamatira: Kubatana kwedhaka kunokanganisawo kukwanisa kwayo kunamatira kune zvidhinha kana matombo. Kana dhaka rakaoma zvakanyanya, rinogona kusabatana nepamusoro, uye kana rakanyorova, rinogona kunge risina simba rakakwana rekubata zvidhinha kana matombo pamwechete.

3. Simba: Kubatana kwedhaka kunokanganisawo simba rayo. Kana dhaka racho rakaoma zvakanyanya, rinogona kunge risina zvinhu zvekusungira zvakakwana kuti zvibatanidze zvidhinha kana matombo pamwe chete, uye kana yakanyanya kunyorova, inogona kusaoma zvakanaka uye inogona kunge isina simba rakakwana kuti rikwanise kumira kurema kwechivako.

Nzira yekuona sei Kuenderana kweWet-Musanganiswa Masonry Mortar?

Pane nzira dzinoverengeka dzekuona kuenderana kwemvura-yakasanganiswa masonry dhaka. Nzira dzakajairika ndeyekuyerera tafura bvunzo uye cone yekupinda bvunzo.

1. Flow Tafura Muedzo

Iyo yekuyerera tafura bvunzo inzira yakapusa uye yakashandiswa zvakanyanya kuona kuenderana kwemvura-yakasanganiswa masonry dhaka. Muedzo unosanganisira kuisa sampuli yedhaka patafura yekuyerera uye kuyera dhayamita yedhaka rakapararira. The flow table is a flat, denderedzwa tafura inotenderera nekumhanya kwakamira. Muenzaniso wedhaka unoiswa pakati petafura, uye tafura inotenderedzwa kwemasekonzi gumi nemashanu. Mushure memasekonzi gumi nemashanu, dhayamita yedhaka rinopararira rinoyerwa, uye kuwirirana kwedhaka kunotsanangurwa zvichienderana nehupamhi.

Iyo dhayamita yedhaka rakapararira inopimwa uchishandisa mutongi kana caliper. Iko kuwirirana kwedhaka kunotsanangurwa zvichienderana nehupamhi hwehutu hwekupararira, sezvinotevera:

- Kana hupamhi hwehutu hwekupararira huri pasi pe200 mm, dhaka racho rakaoma zvikuru, uye mvura yakawanda inodiwa.
- Kana iyo dhayamita yedhaka rekupararira iri pakati pe200 mm ne250 mm, dhaka rine hukama hwepakati, uye hapana kugadziriswa kunodiwa.
- Kana iyo dhayamita yedhaka yakapararira inopfuura 250 mm, dhaka rakanyanya kunyorova, uye zvimwe zvakaoma zvinhu zvinodiwa.

2. Cone Penetration Test

Iyo cone yekupinda bvunzo ndiyo imwe nzira yekuona kuenderana kwekunyorova-musanganiswa masonry dhaka. Muedzo uyu unosanganisira kuisa muenzaniso wedhaka mumudziyo wakaita sekoni uye kuyera kudzika kwekupinzwa kwekoni yakajairwa mudhaka. Koni yakagadzirwa nesimbi uye ine huremu hwe300 g uye kona yekoni ye30 degrees. Mudziyo unozadzwa nedhaka, uye koni inoiswa pamusoro pedhaka. Koni inozotenderwa kunyura mudhaka pasi pehuremu hwayo kwemasekonzi makumi matatu. Mushure memasekondi makumi matatu, kudzika kwekupinda kwekoni kunoyerwa, uye kuwirirana kwedhaka kunotsanangurwa zvichienderana nekudzika kwekupinda.

Kudzika kwekupinda kunopimwa pachishandiswa rura kana kuti caliper. Kubatana kwedhaka kunotarirwa zvichienderana nekudzika kwekupinda, sezvinotevera:

- Kana iyo yakadzika yekupinda isingasviki 10 mm, dhaka rakanyanya kuoma, uye mvura yakawanda inodiwa.
- Kana kudzika kwekupinda kuri pakati pe10 mm uye 30 mm, dhaka rine chimiro chepakati, uye hapana kugadziriswa kunodiwa.
- Kana iyo yakadzika yekupinda inopfuura 30 mm, dhaka rakanyanyisa kunyorova, uye zvimwe zvakaoma zvinhu zvinodiwa.

Mhedziso

Iko kuenderana kwekunyorova-yakasanganiswa masonry dhaka kwakakosha kuve nechokwadi chemhando uye kusimba kwechigadzirwa chakapedzwa. Kusagadzikana kunokanganisa kushanda, kunamatira, uye kusimba kwedhaka. Iyo yekuyerera tafura bvunzo uye koni yekupinda bvunzo inzira mbiri dzakajairwa kuona kuenderana kweyakanyorova-yakasanganiswa masonry dhaka. Nekushandisa bvunzo idzi, vavaki vanogona kuve nechokwadi chekuti dhaka rine kuenderana kwakaringana kwebasa, izvo zvinozokonzera chimiro chakasimba uye chakasimba.
