He taonga parewai – he kupu whakataki poto mo te kingi me te hangarau hanga

He ingoa noa te kingi kumete, ka kiia hoki e etahi ko te toka, he kaihoko raima raima. Ko te moata KINGI HE MOMO HANGA HOU hei whakakapi mo te kumete MIXED LIME rauemi parewai TEKAU rama, ka taea te whakaiti i te nui o te ciment i roto i te kumete, te kaha o te kumete i piki ake i te 12% - 15%, he tino painga ohaoha. Titiro ki te whakaurunga o te kingi o te moata me te hangarau hanga.
 
Āhuatanga Matua:
Engari i te kotakota, whakaitihia te nui o te ciment, whakapai ake i nga ahuatanga o te moata
 
Te whānuitanga o te tono:
He pai mo nga momo whare ahumahi me nga whare taangata i roto i te pereki uku, pereki pereki, pereki tuwhera, paraka sima maku, pereki pereki kore ahi, te raima o roto me waho o te pakitara, te taera raima, te papa, te tuanui, te poraka rori, te kowhatu, te papa o raro, te puna wai. , hanga wharepaku.
 
Āhuatanga Hua:
1> me te pai o te mahi, te whakapai ake i te kaha o te kumete, hei utu mo te kotakota, tiakina sima.
2> he pai te aukati mīti, te aukati me te makuku.
3> Whakapai ake i te kaha herenga moata, hinga i te anga, pakaru, maturuturu onepu me etahi atu ngoikoretanga.
4> Kaore he waikura ki te whakapakari.
5> Ko te whakamarumaru o te taiao matomato, te kore-paitini, te kore e mura, te mauroa kua tino pai ake i te moata noa, he nui te kaha o te moata.
 
ōwehenga inenga moata noa:
1> Moata whakauru: te whakaora wai 40%, tino whakakapi kotakota.
2> moata sima: whakaora sima 10%, te wai whakaora 20%.
 
Tikanga whakamahi:
1 > mahi:
I raro i te ahua o te tauwehenga o te ciment me te onepu kaore e rereke, ringihia te kingi moata ki roto i te wai o te whakaranu me tetahi taputapu ine kia rite ki te rahinga o te nui o te whakaranu. Kia rua nga whakaoho i mua i te mirumiru wai, ringihia te sima me te wai kirikiri ki roto i te taika ranu mo te ranu (me mahara kei te 40% te penapena wai hei tapiri i tenei hua). Ko te wa whakauru moata ko te 2-3 meneti, a ka tae te rite ki te 70-90mm, a ko te mahi hanga he pai rawa atu.
2> taiepa roto:
(1) I mua i te hanganga, me makuku te mata o te masonry, kaore he wai maanu, he pai ake te whakamakuku 2-4 haora i mua.
(2) horoia te upoko me nga wa e rua kia noho tonu, he roa rawa te wa waahi ki te whakamaroke i te wai me te rongoa i te upoko, a ehara i te mea ngawari ki te mahi rua.
(3) Ko te kingi o te kumete he kaha te kaha o te wa, kaore e roa te wa o te mata pakaru, kaore i te tino kainga te penupenu, he pai ki te whakamahi i te rino ki te pehi i te kirikiri tere.
(4) raima taiepa raima, e taea te raima tika rua, pērā i te mata raima he kaihoko kiriata, Me ki te mahi tukatuka atanga.
(5) papa, tuanui raima kia tuatahi muru te mata concave me te convex i waenganui i te pereti, i muri i te mata he kaha rite ki te tikanga tikanga o te raima.
3> Taiepa: ko te nui o te kumete kingi e kore e nui rawa, he tino ngawari ki te pakaru, etahi atu me te raima pakitara o roto he rite tonu.
4> Masonry: Me whakamakuku te mata pereki, kia ki tonu te mata o te masonry.
5> horoia te paparanga parewai: he nui ake te kino o nga waahi ka taea te muru e toru nga wa, ka taea te muru rua.
6> tikanga whakarite tauira pae:
(1) Ko nga momo rauemi mata e whakamahia ana mo te whakamatautau ka ine tika i runga i te tauwehenga whakauru
(2) Ko te whakamatautau o raro ka whakamahia te nuinga
(3) Ko te tikanga rongoa he rongoa paerewa (ko te whakamahana whakamahana he 20+-30 nga nekehanga Celsius, he nui ake i te 90%) te mahana whakamaarama, a ko te tau whakaora he 7 ra, 28 ra ranei.
(4) E rua ki te wha haora i mua i te whakamatautau mo te kaha o te moata, ka taea te tango i te poraka whakamatautau mai i te taiao paerewa me te whakamaroke i roto i te whakamarumaru i mua i te whakamatautau pehanga.
 
Nga tohu hei aro:
1> Ka whakanohoia te moata whakauru ki te waahi o te pupuri wai, kaua e tuu tika ki runga i te papa maroke me te mimiti, mena ka pa ki te mahi o te moata.
2> Rokiroki i roto i te wahi maroke, me te hā, ka whakarongo ki te makuku i roto i te rokiroki me te kawe.
