Abubuwan Kariyar Kankare Masu Sauƙi | Mahimman Ayyuka Masu Kumfa don Kankalin Salon salula
Gaskiya mai ban tsoro: Ƙarshe 60% na kasawar bene na masana'antu farawa kamar yadda layin gashin gashi ya bayyana a farkon 28 kwanaki. Kuma a nan ne mai kisa-mafi yawan waɗannan fasa-kwai da aka iya hana su zabar dama kankare ƙarfafa zaruruwa ga masana'antu dabe maimakon dogaro da ragamar waya mai walda.
Da yawa daga cikin mu a filin an kona ta da raga. Kun san rawar jiki-“Kawai ja ragamar sama yayin da kuke zubawa.” Kuma rabin lokacin yana ƙarewa a ƙasa, yin komai. Fiber ba su da wannan matsala. Suna ko'ina, a cikin kowane cubic inch. Bari mu yi tafiya daidai yadda za mu sami wannan daidai.
Mataki 1: Zaɓi nau'in Karfe na Fiber ɗin ku, Macro-Synthetic, ya da Micro
Ba duk zaruruwa daidai suke ba. Zaɓin ku ya dogara da bayanin martabar kaya da aikin slab. Anan ga rushewar da muke amfani da shi akan kowane aiki:
- Karfe zaruruwa (ASTM A820): Mai ɗaukar nauyi. Mafi dacewa don shimfidar masana'antu masu nauyi tare da zirga-zirgar forklift ko kayan tarawa. Suna ba da taurin tsarin bayan fashe. Yi tsammanin kashi tsakanin 20-40 kg/m³ (35-65 lb/yd³). Suna yi ba hana tsagewar filastik - wannan ba aikinsu bane.
- Macro-synthetic fibers (Saukewa: ASTM C1116, Nau'in III): Madadin zamani zuwa karfe. Suna bayar da tauri mara lalacewa. Cikakke don ɗakunan ajiya na firiji ko kuma wuraren da ke damun tsatsa. Sashi: 4-8 kg/m³ (6-13 lb/yd³). Suna samar da ƙarfafawa na biyu kuma suna inganta juriya na tasiri.
- Micro-synthetic fibers (Saukewa: ASTM C1116, Nau'in I): The crack 'yan sanda na farko 24 hours. Suna sarrafa fashewar robobi ta hanyar rage ruwan jini da kuma samar da karfin juriya lokacin da simintin ya kasance kore. Sashi: 0.6-1.8 kg/m³ (1-3 lb/yd³). Suna yi ba samar da ƙarfin tsari - kar a dame su da macros.
- Haɗawa: Yana ƙara zama gama gari akan benaye masu haƙuri (misali, VNA warehouses). Haɗuwa na macro-synthetic da micro-synthetic fibers yana ba ku duka sarrafa fashewar farkon shekarunku da tauri na dogon lokaci.. Kuna samun mafi kyawun duniyoyin biyu.
Mataki 2: Rage ragar Waya-Ga Bayanai
Zaren Reddit cike suke da labaran ban tsoro: “Na daga ragamar waya da ƙugiya, kuma har yanzu ya ƙare a ƙasa. Fashe ko'ina.” Muna jin wannan zafi. Bari in nuna muku dalilin da yasa zaruruwa ke yin nasara.
| Siffar | welded Waya raga | Fibers |
|---|---|---|
| Matsayi a cikin slab | Ba abin dogaro - sau da yawa yana ƙarewa a ƙasa | An rarraba daidai gwargwado a ko'ina |
| Crack control-ruwan filastik | Babu | Madalla (tare da micro fibers) |
| Crack control-tsarin | Matsakaici (idan a daidai matsayi) | Madalla (da karfe ko macro) |
| Aiki don shigarwa | Babban-yana buƙatar ɗaure, dagawa, da matsayi | Karamin-ƙara a batch shuka ko wurin aiki |
| Hadarin lalata | Babban (idan an fallasa) | Ƙananan (macro-synthetic) zuwa matsakaici (karfe) |
A wurin aiki, amfani da zaruruwa maimakon raga na iya ceton ku 2-3 awa daya 100 m² na kasa. Wannan kudi ne na gaske. Kuma kuna samun bene tare da ƙarin daidaiton ƙarfi.
Mataki 3: Sami Tsarin Sashi da Mix Daidai
Wannan shi ne inda yawancin mu ke yin kuskure. Ba za ku iya zubar da zaruruwa kawai a saman busassun tara ba kuma ku yi fata ga mafi kyau. Bi wannan jerin:
- Batch ruwa da farko. Ƙara 75% na ruwan ku hadawa da ganga.
- Ƙara m jimlar. Wannan yana haifar da aikin zazzaɓi.
- Ƙara zaruruwa a hankali. Domin karfe zaruruwa, bel mai ɗaukar kaya ko mai watsawa mai sarrafa kansa ya fi kyau. Don macro-synthetics, ƙara su 30-45 seconds. Micro fibers na iya shiga a matsayin jakar da aka riga aka auna.
- Ƙara siminti da tara mai kyau. Sai sauran 25% na ruwa.
- Mix don 5-7 mintuna a hadawa gudun (ba agitating gudun). Duba don rarraba iri ɗaya. Bai kamata ku ga gungu ko “gidajen tsuntsaye.”
- Duba slump. Yi tsammanin raguwar 25-50 mm (1-2 inci) idan aka kwatanta da farantin kankare. Kada a ƙara ƙarin ruwa don ramawa-wanda ke lalata rabon siminti na ruwa kuma yana raunana ƙasa. Yi amfani da superplasticizer maimakon idan an buƙata.
Dole ne sashi ya zama daidai. Domin karfe zaruruwa, amfani daidai 25 kg/m³ don aikin masana'antu haske, 35 kg/m³ domin matsakaicin wajibi, kuma 45 kg/m³ domin nauyi nauyi (misali, digo-farar guduma). Don macro-synthetics, wurin dadi shine 6 kg/m³ don yawancin aikace-aikacen masana'antu.
Mataki 4: Daidaita Matsayinka da Hanyoyin Kammalawa
Wannan shi ne bangaren da ya karkace daga fili kankare. Idan kun taɓa yin aiki da ragar waya kawai, kuna buƙatar canza tsarin ku:
- Stiff mix shine abokin ku. Fibers suna rage yawan aiki, don haka niyya wani slump na 75-100 mm (3-4 inci) a sanyawa. Cakuda mai tauri yana taimakawa wajen rarraba zaruruwa daidai gwargwado kuma yana hana su zama.
- Yi amfani da sikelin Laser ko abin nadi. Tare da zaruruwa, wani jijjiga truss screed yana aiki, amma dole ne ku ci gaba da motsi. Kada ku yi rawar jiki-wanda ke tura zaruruwa ƙasa. Tsaya zuwa 15 seconds a kowace sakawa don masu jijjiga na ciki.
- Ƙarshen lokacin canje-canje. Fibers, musamman micro-synthetics, rage ruwan jini. Dole ne ku fara hawan bijimi da tudun wuta 15-30 mintuna kafin haka fiye da yadda za ku yi da kankare. Kalli yadda saman ya rasa sheen.
- Filayen da aka fallasa a saman? Wannan yana faruwa tare da zaruruwan ƙarfe idan kun kunna wuta da wuri ko kuma da ƙarfi. Dakatar da troweling da zaran an rufe saman kuma yayi yawa. Domin karfe zaruruwa, wucewa ta ƙarshe tare da tulun ƙarfe mai wuya zai iya haɗa su. Don macro-synthetics, ba kasafai suke zuwa saman ba idan kun bi lokacin da ya dace.
An ambaci wani mai amfani da Reddit: “Na yi amfani da zaruruwan ƙarfe kuma na sa dajin su manne. Dole ne a niƙa ƙasa duka. Koyi hanya mai wahala-bari siminti ya daɗe kafin yin tagumi.” Mun kasance a can.
Mataki 5: Zane Haɗuwa da Ƙarfafawa tare da Fibers a Zuciya
Fibers suna canza wasan don ƙirar haɗin gwiwa, amma ba sa kawar da buƙatar haɗin gwiwa. Ga sabon littafin ƙa'ida:
- Tazarar haɗin gwiwa na iya ƙaruwa. Da karfe ko macro zaruruwa, za ka iya sararin gani-yanke gidajen abinci a 6-9 mita (20-30 ƙafafu) maimakon na hali 4.5 mita (15 ƙafafu) don kankare a fili. Wannan yana rage kulawa kuma yana inganta hawan hawa.
- Shirye-shiryen ƙarami har yanzu yana da mahimmanci. Fibers suna ƙara tauri, amma ba su gyara wani m subgrade. Modull ɗin ku na amsawar ƙasa (k - darajar) ya kamata a kalla 0.05 MPa/mm (50 pci) don benaye masana'antu. Karamin zuwa 95% gyara Proctor.
- Load canja wuri a fadin gidajen abinci. Haɗin haɗaɗɗiya yawanci ya isa ga haɗin gwiwa mai ƙarfafa fiber, muddin fadin haɗin gwiwa ya tsaya a ƙarƙashinsa 3 mm (1/8 inci). Don haɗin gwiwa masu nauyi, yi la'akari da ƙara kwandon dowel-fibers kadai ba zai canja wurin kaya ba a haɗin haɗin da aka yanke.
- Katangar tururi sama ko ƙasa? Sanya shingen tururi kai tsaye a ƙarƙashin katako (babu yashi a samansa). Zaɓuɓɓuka ba su rage buƙatun ƙirar tururi mai hana ruwa da kyau (Saukewa: ASTM E1745, Darasi A).
A cikin ɗakunan ajiya na firiji (yawanci -20 ° C), Macro-synthetic zaruruwa sun fi ƙarfe saboda ba sa lalacewa daga sanyin sanyi wanda ke tasowa a ƙarƙashin rufin.. Mun ga karfe zaruruwan tsatsa da kuma fita bayan 3 daskare-narke hawan keke.
Motsi na gaba: Gwaji, Kar a yi tsammani
Duba, Ba zan gaya muku ku sayi takamaiman tambari ba. Wannan ba salona bane. Ga abin da nake so ku yi: Yi oda dutsen izgili. Aƙalla 3m x 3m (10 ft x 10 ft). Yi amfani da mahaɗin kankare daidai, zaren nau'in, da kuma kammala ma'aikatan da kuke shirin amfani da su akan ainihin aikin.
Sa'an nan kuma yi wannan:
- Jira 28 kwanaki. Take 3 cores daga izgili. Aika su zuwa lab don Saukewa: ASTM C1609 (flexural taurin gwajin).
- Dubi saman da ya karye. Ƙididdige zaruruwa a kowane inci murabba'i. Idan kuna da ƙasa da 2 zaruruwa da cm² (12 zaruruwa a cikin ²), ƙara yawan sashi.
- Duba saman. Babu fallasa zaruruwa? Yayi kyau. Idan kun ga zaruruwa, daidaita jadawalin ƙarewa.
Kankare ƙarfafa zaruruwa ga masana'antu dabe ba sihiri ba. Kayan aiki ne. An yi amfani da shi daidai, za su ba ku bene wanda ya wuce ginin. An yi amfani da shi ba daidai ba, za ku yi niƙa da faci na tsawon shekaru. Maida abin ba'a abokinka.
Mun ga bayanai. Mun gyara gazawar. Yanzu je ku zuba wani bene wanda ba zai tsage ba.
