Kodi kuchuluka kwa simenti mu chiŵerengero chosakanikirana cha matope a masonry kumakhudza bwanji kusunga madzi kwa matope?

Mfundo yamtengo wapatali yomanga matope a masonry ndi gawo lofunika kwambiri la nyumbayi, kuti zitsimikizire mtundu wonse wa mgwirizano, kumanga ndi kukhazikika.Pali zinthu zambiri zomwe zimakhudza mphamvu.Ngati zinthu zilizonse mu chiŵerengero chosakaniza ndi osakwanira, kapena zikuchokera sikokwanira, izo zingakhudze khalidwe wonse, kuti apange zinthu za mphamvu kalasi muyezo, m'pofunika kumvetsa mfundo zakuthupi, kuchuluka, chitsanzo ndi zina zotero. kotero kuti zida zosiyanasiyana zitha kusakanikirana mugawo linalake.Kuchuluka kwa mchenga wogwiritsidwa ntchito mu chiŵerengero chosakanikirana cha matope a masonry kumasinthidwa mosalekeza molingana ndi magiredi amphamvu.Ngati magiredi mphamvu ndi osiyana, m`pofunika kusintha kuchuluka kwa mchenga aliyense kiyubiki mita matope mu nthawi kuonetsetsa kuti kuchuluka kwa mchenga kukumana mfundo kamangidwe, kukwaniritsa zomanga, kupulumutsa ndalama yomanga.Zimatsimikiziridwa ndi machitidwe kuti kuchuluka kwa simenti yomwe imagwiritsidwa ntchito mumatope otsika kwambiri ndi ochepa kuposa mumatope amphamvu kwambiri.Kuti tipeze matope abwino, tifunika simenti ndi mchenga wouma kupyolera mumtundu wina wosankhidwa, ndiyeno onjezerani madzi oyenerera kusakaniza, kuti apange matope omangamanga, voliyumu yamatope idzachepetsedwa ndi 10%;Nthawi zambiri, mphamvu ya matope ikakwera, kuchuluka kwa simenti yogwiritsidwa ntchito, simenti yosakanikirana ndi dothi kumawonjezera kuchuluka kwake.Kuchuluka kwa madzi pa unit kumakhudza fluidity ya matope.Dongo lokhalo lokhala ndi madzi oyenerera lingathe kuonetsetsa kuti matopewo ndi osasunthika ndikukwaniritsa zofunikira pakumanga.The osakaniza chiŵerengero cha zomangamanga matope makamaka laimu-mchenga chiŵerengero.Pokhapokha pamene kuchuluka kwa simenti ndi mchenga kumayendetsedwa bwino, ndipo gawo la zonsezi lingathe kugwirizanitsa zipangizo zomangira zamphamvu kuti zitsimikizire kuti zomangamangazo zili bwino.

Kugwiritsa ntchito koyenera komanso kwasayansi kwa simenti ndikoyenera kutsimikizira mtundu wa matope.Kuchuluka kwa simenti kumasintha ndi mphamvu ya matope, kuti mudziwe kuchuluka kwa simenti, ziwirizi zimagwirizana, ndiko kuti, kuchuluka kwa mphamvu ya matope, kuchuluka kwa simenti, ndi mosemphanitsa.Kusankha kuchuluka kwa simenti ndi kutsatira mfundo yochepetsera simenti kungathe kuonjezera kuchuluka kwa matope osungira madzi, kumapangitsa kuti matope asungidwe bwino, kupewa kusweka kwa njerwa, ndikuwonetsetsa kuti ntchito yomangayo ndi yabwino.Mchenga fineness umathandizanso mwachindunji kuchuluka kwa simenti, ang'onoang'ono fineness, lalikulu matope zili, mchenga fineness modulus pakati 2.3 ~ 3.0, kuonetsetsa kuti matope zili mu matope mix chiŵerengero zosakwana 5%.Mchenga wapakatikati womwe umagwiritsidwa ntchito mumatope omanga ndi chinthu choyenera.Sizingagwiritse ntchito mchenga wabwino kapena mchenga wabwino kwambiri kuti upewe kusamata kokwanira komanso kukhudza kapangidwe kake.

Miyezo ya konkire yoyendetsera kugwiritsa ntchito simenti imatha kukwaniritsa cholinga cha zomangamanga zapamwamba pokhapokha ngati njirayo ndi yololera.Kuwongolera mlingo wa simenti ndiye chinsinsi chowonetsetsa kuti chiŵerengero chosakanikirana cha matope a miyala.Mmodzi ndi ntchito masekeli sikelo simenti kulemera, mwa muyeso wabwino, mogwira kuonetsetsa kuchuluka kwa simenti, kuti ndende ya simenti lizilamuliridwa, kawirikawiri kuchuluka kwa ulamuliro simenti mu 2%.Chachiwiri, malo omanga ayenera kugwiritsa ntchito mita yolondola kwambiri, kusanthula kothandiza kwa kuchuluka kwa zinthu zosiyanasiyana zamatope kuti adziwe gawo loyenera.Chachitatu ndi kuchepetsa nthawi yosakaniza simenti.Mosamalitsa anapereka nthawi, kukumana ndi kusanganikirana nthawi zosachepera 2 Mphindi ya muyezo, mu kusakaniza ndondomeko, kufunika kulamulira liwiro, zonyansa kuchotsa, kupewa kwambiri laimu midadada zimakhudza mphamvu.Pambuyo kusakaniza, zipangizo zina ziyenera kugwiritsidwa ntchito mwamsanga, kuti zisakhudze mphamvu zonse.Chachinayi, kugwiritsa ntchito mwanzeru zowonjezera.Ngati mukufuna kugwiritsa ntchito zowonjezera, muyenera kutsatira mosamalitsa miyezo, payenera kukhala kuyesa kokhazikika, pali magawo asayansi othandizira.Chachisanu, kukwaniritsa zofunika zenizeni.Zomangamanga zosiyanasiyana, muyezo wa matope ndi wosiyana, malinga ndi malo omanga malo, kusintha koyenera kwa simenti, kusintha koyenera kwa chiŵerengero chosakaniza, chifukwa chiŵerengero chosakaniza sichinakhazikitsidwe, malinga ndi mitundu yosiyanasiyana ya simenti, kalasi, kusintha kwa ntchito, sewera mbali.
