Drymix Mortar nikoreshwa cyane kandi nikimwe mubikoresho byingenzi mubwubatsi bugezweho. Igizwe na sima, umucanga hamwe nibindi. Isima nigikoresho nyamukuru cya sima. Uyu munsi reka twige byinshi kumiterere yibanze ya drymix mortar.
Amabuye y'ubwubatsi: Nibikoresho byubwubatsi byateguwe nibikoresho bya sima, igiteranyo cyiza, imvange namazi muburyo bukwiye.
Masonry mortar: Amabuye ahuza amatafari, amabuye, amabuye, nibindi mububiko bwitwa masonry mortar. Masonry mortar igira uruhare mugukomeza sima no kohereza imizigo, kandi nigice cyingenzi cyububiko.
1. Ibikoresho byo guhimba amabuye ya masonry
(1) Gushimangira ibikoresho no kuvanga
Ibikoresho bya sima bikunze gukoreshwa mububiko bwa masonry birimo sima, paste lime, hamwe na gypsumu.
Urwego rwimbaraga za sima zikoreshwa mumabuye ya masonry zigomba gutoranywa ukurikije igishushanyo mbonera. Urwego rwimbaraga za sima rukoreshwa muri sima ya sima ntigomba kurenza 32.5; igipimo cyimbaraga za sima zikoreshwa muri sima ivanze na sima ntigomba kurenza 42.5.
Mu rwego rwo kunoza imikorere ya minisiteri no kugabanya ingano ya sima, paste zimwe zindimu, paste y ibumba cyangwa ivu ryisazi bikunze kuvangwa na sima ya sima, na minisiteri yateguwe murubu buryo yitwa sima ivanze na sima. Ibi bikoresho ntibigomba kuba birimo ibintu byangiza bigira ingaruka kumikorere ya minisiteri, kandi iyo birimo uduce cyangwa agglomerate, bigomba kuyungurura hamwe na santimetero 3 ya mwobo. Ifu ya lime yamenetse ntishobora gukoreshwa muburyo bwa minisiteri.
(2) Igiteranyo cyiza
Umucanga ukoreshwa muri minisiteri yubukorikori ugomba kuba umusenyi wo hagati, naho amabuye yamabuye agomba kuba umucanga mubi. Ibyondo birimo umucanga ntibigomba kurenga 5%. Kuri sima ivanze na sima ifite imbaraga zingana na M2.5, ibyondo byumucanga ntibigomba kurenga 10%.
(3) Ibisabwa ku nyongeramusaruro
Kimwe no kongeramo ibivanze muri beto, kugirango tunonosore ibintu bimwe na bimwe bya minisiteri, imvange nka plastike, imbaraga za kare,selile ether, antifreeze, hamwe no kudindiza nabyo birashobora kongerwamo. Mubisanzwe, ibinyabuzima bidasanzwe bigomba gukoreshwa, kandi ubwoko bwabyo nibipimo bigomba kugenwa hakoreshejwe ubushakashatsi.
(4) Ibisabwa ku mazi ya minisiteri ni bimwe na beto.
2. Ibikoresho bya tekinike ya masonry mortar ivanze
(1) Amazi ya minisiteri
Imikorere ya minisiteri itemba munsi yuburemere bwayo cyangwa imbaraga zo hanze byitwa fluidity ya minisiteri, nayo bita guhuzagurika. Ironderero ryerekana umuvuduko wa minisiteri ni urugero rwo kurohama, bipimwa na metero ihoraho, kandi igice cyacyo ni mm. Guhitamo ibimasa bya minisiteri mu mushinga bishingiye ku bwoko bw'imyubakire n'imiterere y'ikirere cyubaka, bishobora gutoranywa hifashishijwe imbonerahamwe 5-1 (“Kode yo kubaka no kwemerera ubwubatsi bwa Masonry” (GB51203-1998)).
Ibintu bigira ingaruka kumazi ya minisiteri ni: gukoresha amazi ya minisiteri, ubwoko nubunini bwibintu bya simaitima, imiterere yingingo hamwe nu ntera ya agregate, imiterere na dosiye yo kuvanga, uburinganire bwo kuvanga, nibindi.
(2) Kubika amazi ya minisiteri
Mugihe cyo gutwara, guhagarara no gukoresha minisiteri ivanze, birinda gutandukanya amazi nibikoresho bikomeye, hagati yigituba cyiza hamwe, kandi ubushobozi bwo kubika amazi nububiko bwamazi ya minisiteri. Ongeramo urugero rukwiye rwa microfoam cyangwa plastike irashobora kunoza cyane gufata neza amazi no gutembera kwa minisiteri. Kugumana amazi ya minisiteri bipimwa na metero yo gusibanganya minisiteri, kandi bigaragazwa no gusibanganya (. Niba gusiba ari binini cyane, bivuze ko iyo minisiteri ikunda gusibanganywa no gutandukana, bidakwiriye kubaka no gukomera kwa sima. The. Urwego rwo gusibanganya marimoni ntirugomba kurenza 3 0mm.
(3) Gushiraho igihe
Igihe cyagenwe cyo kubaka minisiteri kizasuzumwa hashingiwe ku kurwanya kwinjirira kugera kuri 0.5MPa. Isima ya sima ntigomba kurenza amasaha 8, na sima ivanze na sima ntigomba kurenza amasaha 10. Nyuma yo kongeramo ibivanze, bigomba kuba byujuje igishushanyo mbonera.
3. Ibikoresho bya tekinike ya minisiteri yububiko nyuma yo gukomera
Imbaraga zo guhonyora za minisiteri zikoreshwa nkimbaraga zayo. Ingano isanzwe ni 70.7 mm kubic, itsinda ryibigereranyo 6, kandi umuco usanzwe ugera kuminsi 28, kandi impuzandengo yo kwikuramo (MPa) irapimwa. Masonry mortar igabanijwemo amanota atandatu yimbaraga ukurikije imbaraga zo guhonyora: M20, M15, M7.5, M5.0, na M2.5. Imbaraga za minisiteri ntabwo ziterwa gusa nuburinganire nuburinganire bwa minisiteri ubwayo, ahubwo bifitanye isano nimikorere yo kwinjiza amazi yibanze.
Kuri sima ya sima, imbaraga zikurikira zirashobora gukoreshwa mukugereranya:
(1) Intandaro idakurura (nk'ibuye ryinshi)
Intandaro idashiramo ni cyo kintu nyamukuru kigira ingaruka ku mbaraga za minisiteri, ahanini ikaba isa n’iya beto, ni ukuvuga ko igenwa ahanini n’imbaraga za sima n’ikigereranyo cy’amazi-sima.
(2) Urufatiro rukurura amazi (nk'amatafari y'ibumba n'ibindi bikoresho byoroshye)
Ni ukubera ko urwego shingiro rushobora gukuramo amazi. Iyo ikurura amazi, ubwinshi bwamazi yagumishijwe muri minisiteri biterwa no kugumana kwayo, kandi ntaho bihuriye nigipimo cyamazi-sima. Kubwibyo, imbaraga za minisiteri muriki gihe zigenwa ahanini nimbaraga za sima nubunini bwa sima.
Bond imbaraga za masonry mortar
Amabuye ya masonry agomba kuba afite imbaraga zihagije zo guhuza ububiko muri rusange. Ingano yimbaraga zifatika za minisiteri izagira ingaruka kumbaraga zogosha, kuramba, gutuza no kunyeganyega kwa masonry. Mubisanzwe, imbaraga zifatika ziyongera hamwe no kwiyongera kwingufu zo kwikuramo za minisiteri. Ihuriro rya minisiteri naryo rifitanye isano nubuso buringaniye, urugero rwubushuhe hamwe nuburyo bwo gukiza ibikoresho byububiko.
