A. Kufunika kwa madzi osungira
Kusunga kwamadzi kwa matope kumatanthauza kuthekera kwa matope kuti asunge madzi. Matope omwe ali ndi madzi osavomerezeka amatuluka magazi ndi tsankho panthawi yosungira ndikusungirako, ndiye kuti madzi amayandama pamwamba, ndi mchenga ndi simenti pansi. Iyenera kukhala yolimbikitsidwa musanagwiritse ntchito.
Mitundu yonse yazikulu zomwe zimafunikira matope kuti zomanga zizikhala ndi mayamwidwe ena amadzi. Ngati madzi osungidwa ndi matope ndi osauka, matope osakanikirana-osakanizika adzatengeka akangotsala pang'ono kulowa ndi chipikacho kapena maziko pa matope. Nthawi yomweyo, thambo la matope limatulutsa madzi m'mlengalenga, zomwe zimapangitsa kuti chinyontho chosakwanira matope chifukwa cha madzi osowa madzi, ndipo nthawi yomweyo amakhudzanso kukula kwamphamvu kwamphamvu. , chifukwa cha mphamvu, makamaka mawonekedwe pakati pa matope owuma ndi maziko osanjikiza. imakhala yotsika, ndikupangitsa matope kuti asweke ndikugwa. Pa matope ndi kusungidwa kwamadzi, simenti hydration ndizokwanira, mphamvu zimatha kupangidwa mwachizolowezi, ndipo zimatha kukhala bwino mpaka maziko osanjikiza.
Matope okonzeka-osakanizika nthawi zambiri amapangidwa pakati pa zotchinga madzi kapena kufalikira m'munsi, ndikupanga kwathunthu pamodzi ndi maziko. Zomwe zimapangitsa kuti madzi osayenda bwino a matope pa projekiti akhale motere:
1. Chifukwa cha kutaya kwamadzi kwambiri kuchokera ku matope, kumakhudzanso mphamvu yanthawi zonse, ndikuchepetsa mphamvu yolumikizirana pakati pa matope ndi pamwamba pake, komanso amachepetsa mphamvu ya zomangamanga, potero kuchepetsa mtundu wa ntchitoyi.
2. Ngati matope sanagwirizane bwino, madziwo amatengedwa mosavuta ndi njerwa, kupanga matope owuma komanso andiweyani, ndipo kugwiritsa ntchito kuli kosiyanasiyana. Ntchitoyi ikakhazikitsidwa, sikuti zimangokhudza kupita patsogolo, komanso kumapangitsa khoma kukhala kuwonongeka chifukwa cha srinka.
Chifukwa chake, kuwonjezera madzi osungira matope sikopindulitsa, komanso kumawonjezera mphamvu.
B. Njira zosungitsira zamadzi
Njira yothetsera vutoli ndikuthirira maziko, koma ndizosatheka kuonetsetsa kuti mazikowo amanyozedwa. Cholinga chabwino cha hydractive cha simenti pamtunda ndi: Chithandizo cha simenti hydrate chimalowa m'munsi limodzi ndi njira yolumikizira madzi, ndikupanga kulumikizana kokwanira "kuti akwaniritse mphamvu yofunikira.
Kuthirira mwachindunji pamtunda kumayambitsa kufalikira kwakukulu m'madzi kuyamwa kwa maziko chifukwa cha kusasiyana kwa kutentha, kuthirira nthawi, ndikuthirira kufanana. Maziko ali ndi mayamwidwe ochepa madzi ndipo apitiliza kuyamwa madzi m'matope. Sitsaratimenti hydrade isanachitike, madziwo amalowetsedwa, zomwe zimakhudza kulowetsedwa kwa simenti hydration ndi zinthu zothandizirana mu matrix; Mbali ili ndi mayamwidwe ambiri, ndipo madzi mu matope amayenda pansi. Kuthamanga kwa sing'anga kosachedwa, ndipo ngakhale wolemera kwambiri wamadzi umapangidwa pakati pa matope ndi matrix, omwe amakhudzanso mphamvu ya mgwirizano. Chifukwa chake, kugwiritsa ntchito njira yofananira ya chimake sikungangotha kuthana ndi vuto la madzi othamanga, koma idzakhudzanso mgwirizano pakati pa matope ndi maziko.
C. Udindo wa madzi abwino
Kusunga kwa madzi kwakukulu kwa matope kuli ndi zabwino zambiri:
1. Magwiridwe antchito abwino amapangitsa matope kuti atsegule nthawi yayitali, ndipo ali ndi maubwino omanga dera lalikulu, moyo wautali mu chidebe, ndikusinthanitsa ndi kugwiritsidwa ntchito kwa batch.
2. Magwiridwe antchito abwino amapangitsa simenti mu matope mokwanira, moyenera kugwirira ntchito matope.
3. Matope ali ndi magwiridwe antchito abwino kwambiri, omwe amapangitsa kuti matonge atakhala ochepera tsankho komanso magazi, komanso amasintha matope ndi olimbikitsa a matope.
