Setha amandla ngokhonkolo, kuye ngokuthi lokushisa: isheduli

Omunye izinkomba ebaluleke kakhulu izinga ukhonkolo ungamandla yayo. Uma ubheka namazinga isimo, kusho ukuthi bangakwazi ukuthola izimo kokucindezelwa. Ngokusho kwabo, amandla kungaba ulingana kumkhawulo M50-800. Njengoba omunye Balisebenzisa kakhulu kukhona sha kasimende M-500. abakhi abaningi abaqeqeshiwe kanye nabasunguli yangasese acabangele schedule isethi amandla material. Mayelana naye, futhi kuzoxoxwa ngezansi.

Ngoba wena, lolu lwazi futhi singaba usizo, kusukela kuwo ungakwazi ukuthola ngokusebenzisa ezinye kwesikhathi esithile ngemva ukuxuba ikhambi usungaqala umsebenzi olwengeziwe. Lokhu kungenxa yokuthi manipulation ukwakhiwa kungabanga yokulayisha ezakhiwe ukhonkolo. Ngokuvamile ngokuhlanganyela esimweni izisekelo, okumele igcinwe izinsuku ezingu-28 ngaphambi kokuqala ukwakhiwa izindonga.

Setha ngamandla isheduli

Setha wamandla ukhonkolo kuye ngokuthi lokushisa kunqunywa igrafu elimelela isikhawu sesikhathi. Phakathi nalokho kubingelelana, ikhambi iba izakhiwo zokusebenza, khona-ke kungenzeka ukuba afeze kumiswa ungqimba yokuqedela. Luhlelo sokwelapha - kulokhu, okuyilona elidingekayo ukuze kuzuzwe oyifunayo ukhonkolo amandla amagugu. Uma une kwezimo ezivamile, ukwakheka ngeke abavuthiwe sezinsuku ezingu-28.

Zingakapheli izinsuku eziyi-5, ungakwazi ukugcina angawokuphulukisa okusheshayo kakhulu. Emva kwalesi sikhathi kubuya impahla ifinyelela amandla angu-70. umsebenzi Okwalandela kufanele kuqhutshwe kuphela ngemva kwezinsuku ezingu-28, ngoba kuphela ke impahla kuyofinyelela 100 phesenti izinga lokuphepha.

Ukuqina bese usetha amandla ukhonkolo zenzeka ngendlela ehlukile ngamunye icala ngabanye. Ukuze sithole isikhathi, kwenziwe ukuhlolwa amasampuli. I ukufudumala e Monolithic ukwakhiwa kwezindlu ukuthola izakhiwo elikhulu sokuqanjwa abazenzi eminye imisebenzi. Ngokwesibonelo, impahla inakekelwa ku formwork, futhi ishiywe uvuthwe emva ukususwa ezicijile. Setha amandla ngokhonkolo, kuye ngokuthi lokushisa kuyokwenzeka lapho isikhathi ezahlukene isikhathi. Lokhu kuchazwe iqiniso lokuthi kungenzeka imisebenzi olwenziwa phakathi nenkathi ebandayo. Kulokhu, ukufikela isikhathi namandla grade kudingekile ukunikeza Ukushisa ukhonkolo ungangenisi amanzi impahla. Lokhu kungenxa yokuthi i-ukwehla kwezinga lokushisa kubamba inqubo polymerization.

Izincomo ukusheshisa

Ukuze luhambe ngokushesha uhlelo angawokuphulukisa futhi sinciphise isikhathi uhlale leyo nto, kubalulekile ukusebenzisa peskobeton, lapho amanzi ongaphakeme ukuqinisa isilinganiso. Uma lokhu isilinganiso kuyinto 1 kuya kwele 4, isikhathi uzobe onomfutho kabili. Ukuze kuzuzwe umphumela onjalo, ukwakheka kumele kuzosungulwa plasticizers. Nciphisa inkathi nokuvuthwa we impahla kanye kungaba eyayenziwe ngokwandisa lokushisa.

Ukwencika ezingeni angawokuphulukisa impahla lokushisa izinkomba

Setha amandla ngokhonkolo, kuye ngokuthi lokushisa impahla zizokwenzeka ngezindlela ezahlukene. Njengoba isibonelo, cabanga grade ngokhonkolo ku ezahlukene M-200 no-M-300, okuyinto ivaliwe ku Portland usimende ne amamaki uhla M-400 no-M-500. Emini impahla ifinyelela amandla compressive amaphesenti amathathu, uma izinga lokushisa elilingana -3 ° C. Ngaphansi kwale mibandela ukuthi ingxube uzoba lokushisa at +30 ° C, amandla ngosuku kungaba 35%.

Ngokuhamba amandla ezintathu ngosuku ifinyelela 8% uma izinga lokushisa ozokufunda kuzokusiza ukuba alingane -3 ° C. 60% amandla kuyofezwa lapho izinga lokushisa +30 ° C nenkathi efanayo. Uma izinga lokushisa ozokufunda kuzokusiza ukuba alingane +5 ° C izinsuku ezingu-28, amandla impahla kuyoba 77%. amandla Ingabe Ohulumeni Banalo Lonke kuyofezwa ezinsukwini ezingu-14, uma izinga lokushisa impahla ilingana +30 ° C.

isilawuli Process

Isethi amandla ukhonkolo kuye lokushisa ukuthi wokhela. Nokho, kubalulekile ukulandela inqubo e ngesonto lokuqala. Imisebenzi ihlose ukuhlinzeka izimo ukuchayeka, wezwakalisa njengoba:

• bafudumale electric;
• hydration;
• ukufukamela umswakama isithiyo futhi izinto ukushisa-nangokuvikela;
• amalahle isibhamu ukushisa.

Uzodinga sinake ogelezayo nokumanzisa we ebusweni. Ngemva kwesonto kwenzeke ekwenzeni design Ukwakheka lingalayishwa, lokhu kuyiqiniso uma izinga lokushisa komoya ilingana 25-30 ° C.

Ukuze uthole ukwaziswa okwengeziwe ngezigaba elapha

Ukuqonda ukhonkolo wathela okwenzeka ngosuku lokuqala ngemva ekuwulungiseleleni. Umakhi Private ngempela odinga ukukwazi ukwencika iqoqo amandla letivakalako lokushisa air. Ngokwesibonelo, e sezulu esifudumele, lapho izinga lokushisa ngaphandle ngaphakathi 20 ° C, kokuquleka kuzokwenzeka emahoreni. Inqubo kuzoqala kwamahora ambalwa, ukubala kuyadingeka ukuze ukuqhuba emva izingxenye uxhumano, futhi kwaphothulwa ngemva 3.

isikhathi cool

Lapho kubanda ukuqala nokuphela sokushona kushintshile. Ukuze siqonde esingaphezu kosuku kuyoba okwanele. Uma izinga lokushisa komzimba at zero ke inqubo uzoqala phezu okungenani amahora angu-6 emva ukuxuba. Ngaphansi kwezimo ezinjalo, kuthatha amahora 20, Countdown luqala ngemva isixazululo izoba formwork. On a hot usuku isikhathi sesinciphile. Lokhu kubonisa ukuthi ngezinye izikhathi ukubeka kudingeka imizuzu 10 kuphela.

viscosity encishisiwe yesixazululo

Une ukuba zihlolwe ngamandla ukunxenxa ngokhonkolo, kuye ngokuthi lokushisa. Kubalulekile ukwazi nokunciphisa viscosity. In the isinyathelo sokuqala ingxube uzobuyisa ukuhamba. Phakathi nalesi sikhathi, umthelela mechanical kungenzeka bafakela zezinto ezibonakalayo nezingokomoya ukwakhiwa lapho sisengakwazi lokulolonga. Nweba elapha isinyathelo kungaba thixotropy, okuzosiza ekunciphiseni viscosity ngenkathi ukuhlinzeka isinyathelo lokukhanda.

Isibonelo esihle kungaba isixazululo, wavukwa mixer ukhonkolo. Phakathi nale nkathi, ikhambi uzohlala isikhathi eside esigabeni sokuqala. Kodwa-ke kumele kukhunjulwe ukuthi abaningi izinqubo kubangele izinguquko ezingenakuhlehliswa ikhambi, okungase zibulale izinga ukhonkolo lukhuni. Ngokwesibonelo, uya ngokushesha "ukubekwa uphawu" ehlobo.

ukuqina esiteji

Isethi amandla ukhonkolo, ukuhlela isikhathi elichazwa isihloko iqala emva ukubeka. Le nqubo namanje hhayi njalo ngemva kweminyaka embalwa. Kodwa ngemva kwamasonto 4, ungakwazi ukuchaza brand ukhonkolo. Amandla ozokufunda kuzokusiza ukubuthwa, aphenduka ngejubane elingafani. Amandla esiphezulu sale nqubo kuyokwenzeka phakathi nezinsuku zokuqala 7. Esikhathini Izinsuku ezintathu zokuqala ngaphansi kwezimo ezivamile, amandla ifinyelela 30% ukubaluleka vintage. Phakathi namasonto okuqala amabili yesixazululo ifinyelela 70% amandla yenani kushiwo. Emva kwezinyanga ezingu-3 lolu khetho kuzokwanda 20%, ngemuva inqubo wehlisa ijubane, kodwa hhayi wayeka. 3, inkomba ongama izikhathi 2.

Ngaphezu kwalokho, umphumela lokushisa kuma indaba ukuqina

Setha wamandla ukhonkolo, ikakhulukazi, igrafu zazo echazwe esihlokweni luncike lokushisa. I esibandayo kunjalo, kancane kuzokhulisa amandla. Emazingeni aphansi inqubo wayeka ngokuphelele njengoba yiqhwa amanzi, kodwa inikeza hydration we usimende. Njengoba kwanda lokushisa, isethi izoqhubeka. Kodwa ngenkathi ekunciphiseni inqubo uzoyeka futhi. Uma ekhona modifiers Ukwakheka, isikhathi ukuqina kuyehla, kanti ukushisa lapho inqubo wayeka, ancipha.

Iyatholakala ukwakhiwa okusheshayo kungatholakala ukuthi unekhono unamathisele uphawu amandla ukhonkolo emva 2 amaviki. Kusukela ukufudumala kuzonciphisa inqubo nokuvuthwa we impahla, kungashiwo wagomela ukuthi at 40 ° C Inani vintage kufinyelelwe ngemva kwezinsuku ezingu-7. Ngakho-ke, ukuthelwa ukhonkolo kufanele kwenziwe kushisa. Ebusika ukuqinisekisa kwezimo ezivamile zidinga Ukushisa indaba, futhi bebodwa ukuze akwazi ukufeza umsebenzi onjalo kungaba yinkinga, ngoba imishini ekhethekile liyadingeka. Ngaphezu kwalokho, ikhambi sishisiswe 90 ° C no-ngenhla akwamukeleki.

isiphetho

Hlela iqoqo amandla ukhonkolo, elapha izimo kufanele zihlolwe ngaphambi kokuba uqale umsebenzi. Ngakho, ngokuvumelana nesimiso, uzokwazi ukucacisa, ngokusebenzisa yisiphi isamba isikhathi kungaba kwenziwe bula izakhiwo Monolithic. Ukususa formwork engenziwa kuphela ngemva amandla impahla idlula 50% ukubaluleka vintage.

Sicela ugcine engqondweni ukuthi uma kukholamu lehla ngezansi +10 ° C, lesi silinganiso kufinyelelwe, futhi ngemva 2 amaviki potting. Ngaphansi kwalezi zimo kubalulekile ukucabanga mayelana isixazululo eshubile. Regulatory isikhathi ephephile isethwe amandla angu-50. Khona-ke kokuqhubeka emsebenzini eminye kungenzeka kuphela ngemuva ukubaluleka isixazululo vintage ifinyelela 80%.
