Ɓeydude fiɓnde njamndi e dow wertallo gollordu waɗataa ɗum ɓuuɓde. Lugge slab, distance jokkondire e jolngo toɓɓe forklift ko hiisaaji tati ceertuɗi, heen gooto tan ko ko yowitii e fiɓnde.

Leydi Wonaa Crack-Free Ngam Ina Jogii Fiber

Leɗɗe gollorɗe ina ɓuuɓta sabu dalillaaji joy : ɓuuɓgol palastik, ɓuuɓgol yoorngol, ɓuuɓgol nguleeki, ɓuuɓgol les leydi e ɓuuɓgol ɓurtungol. Fiber njamndi ina moƴƴina no feewi ɗiɗi gadani ɗii, ina wallita tataɓo oo tan ko seeɗa, tee alaa ko waɗata e ɗiɗi gadiiɗi ɗii. So tawii lefol hollitii through-cracks lebbi tati caggal nde ngol waɗtaa, sabaabu mum ko heewi ko ŋakkeende compaction subgrade walla ŋakkeende jokkondiral ɓurngal mawnude wonaa doseeji ŋakkuɗi. Hokkude fiɓnde ko huunde winndereyankoore ngam haɓaade mboros ko huunde ɓurnde heewde fuɗɗoraade hakkille ngam floor mo ŋakkaani. Haala laaɓtuka ko wonde fiber ina wayla ɓuuɓri wootiri yaajndi e ɓuuɓri keewndi, ina addana slab oo yaltinde stres shrinkage no fotiri e nokku ɗo etaade ittude ɓuuɓri rewrude e doseeji tan.

Sarɗiiji ngam yahde gila 200 haa 150 mm

Lefol ngol semmbinaaka ina heɓa mbaawka mum ɓuuɓde e teddeendi ; e fiber, mbaawka ummorii ko e teddeendi hawri e semmbe ɓuuɓɗo caggal ɓuuɓri. Thinning ina waawi waɗeede e miijo kono ina ɗaɓɓi sarɗiiji tati e nder sahaa gooto : modulus toowɗo e gootum e reaksiyoŋ subgrade, teddeendi nder nafooje diisnondiral, e jolngo teddeendi koolniindi to jokkondire. Golle ina usta 200 mm haa 150 walla 170 mm tawa ina ɓeyda doosgal haa 35-45 kg/m3. Kala ko ɓuri ustaare 25% ina haani ƴeewteede slab timmuɗo, wonaa kuulal njuɓɓudi. Toɓɓere wootere ina weeɓi waasde : so lefol ngol ina tiiɗi, ina ɓeydoo sensible e subgrade flatness. Dewgal 5 mm les 3 m njuumri alaa ko nafata e 200 mm, ina addana boowal nokkuwal e 150 mm.

Jokkondire: Ko waɗi Panneeji 6 m Ko Fuɗɗoode Ko woowaa

Distance jokkondire ina jogoo stres shrinkage. Beton laaɓɗo ina heewi waɗeede e panneeji 6 m ; e fiɓnde njamndi ɗum ina waawi mawnude haa 8 walla hay 10 m sabu fiɓnde ndee ina ummina ɓuuɓol timmungol. Mawnude panneeji ina jogii sarɗi : luggiɗde taƴre sawru ina foti yettaade tataɓal teddeendi lefol ngol, taƴre ndee ina foti waɗde caggal nde beton oo heɓi semmbe no feewi kono hade mum ɓuuɓde feeñde, ko ɓuri heewde ko waktuuji 12 haa 24 caggal nde ɓuuɓol mawngol ngol waɗi. Taƴde ko ɓooyi kadi lefol ngol ina ɓuuɓtoo ɗo yiɗi, ko ɗuum waɗi taƴre sawru ndee alaa ko waɗata. Geɗel goɗngel ngel yejjittaa ko distance dowel : mawninde panneeji tawa ina jokki dowel e 300 mm tawa jokkondire ɗee ina njuumta.

20-40 kg/m3 Ko Ɗatal Golle ngam Leɗɗe

Leɗɗe e beton structurel ina kuutoroo doseeji ceertuɗi. Beton gonɗo e mbaydi ina haɗa ɓuuɓde e ɓuuɓde e 30 haa 80 kg/m3 ; lowre ina haɓa e ɓuuɓri e toɓɓere, ɗo 20 haa 40 kg/m3 ina moƴƴina jikkuuji ɓuuɓri e lowre teeŋtunde ina yahra hedde 45. Dow 50 kg/m3 timminde ina ɓeydoo tiiɗde no feewi e ɓuuɓri fiɓnde dowri ina ɓeydoo. Ndeen limre ina hawri e ko ina tolnoo e 0,25% haa 0,5% e njuuteendi, ko ɗum woni limre wootere winndaande laabi ɗiɗi. Waɗde sahaa kala fiɓto-ɗee tuugnorgal e nder ciimtol ngol, so wonaa ɗuum ina wayi no ɓuri hoybude e feccere volume e ɓuri yiɗeede e kiloo ngam huunde wootere.

Flatness e Ƴellitaare Fibre Surface

Jaɓde leydi ina suddii ɓuuɓri, ko heewi ko FF/FL walla 3 m njuumri, kam e kalite dow. Doseeji toowɗi, slump toowɗi e timminde leeltugol fof ina pusnoo fiɓnde e dow leydi, ina peewna ɓuuɓri. Fiɓnde ndee wonaa fiɓnde famɗunde kono ko jokkondire tati : jogaade slump e 140 haa 180 mm, fuɗɗoraade doole ɓuuɓde ɗoon e ɗoon caggal diƴƴe, e dry-shake hardener ɗo haani. Fiber peeñɗo jooni oo ina waawi ɓuuɓde caggal, kono ko ɓuri 3 mm ɓuuɓde ina itta heen feccere e laral ɓooyngal ngal. Wonande depasuuji otomaatik jogiiɗi sarɗiiji ɓuuɓɗi no feewi, jogaade doseeji e walla les 30 kg/m3 e ɓurde yiɗde fiber laaɓɗo 0,55 mm.

Forklift e Racking : Toɓɓere Laamuuji

Ko ɓuri famɗude e teddeendi e dow wertallo gollordu ko forklift. Kammbo 3 t ɓeyda heen jolngo timmungo ina rewi e taƴe nay, ko noon taƴre wootere ina waawi nawde 4 haa 6 t e nder santimeeteeruuji seeɗa. Bending local ummoraade e oon toɓɓere teddeendi ina heewi ɓurde batte teddeendi uniforme. Racking ɓuri tiiɗde : ko jolɗe nay e nder bay, heen gooto fof ina waɗi ko ɓuri 10 t. Ko zuum wazi semmbinde e doseeji ina poti yuurniteede e vursugol toɓɓere ɓurnde bonde, wonaa vursugol sarwiis hakkundeejo.

Ko ɓuri heewde e ŋakkeende faamde e dow wertallo gollordu ko jogaade fiɓnde njamndi ko sabaabu skip saw cuts. Fiber ina ɓeyda mbaawka e tiiɗnaare caggal ɓuuɓol, ina addana ɓuuɓol ɓurde laaɓtude, ɓuuɓde e leeltude udditaade, kono ɗum haɗataa beton ɓuuɓde, ko ɗum waɗi kala jokkondire ɗaɓɓaaɗe ina poti taƴeede haa jooni. Ko woowaa ko taƴde sawru e dow ŋoral koloñaal e nder njuuteendi meeteruuji jeegom, e nder luggiɗde feccere e teddeendi ŋoral ; ɓurɗo luggiɗde addantaa ɓuuɓde e ɓurɗo luggiɗde ina leefna taƴre ndee. Jokkondire isolation njeyaa ko e saraaji koloñaal, e ŋoral mahol e baɗe kaɓirɗe, ɗo reentaade ɓuri heewde e hay doseeji fibre mbaawataa yoɓde. Geɗel gootel ina yejjitee no feewi : lefol ngol ina foti seertude e maale yaajɗe e jolɗe leydi, so wonaa ɗuum mahol ngol ina reena lefol ngol, mbaydi taƴndi ndii ina wayloo no feewi, ɓuuɓol ngol feeñata e hakkunde laawol jolngo. Hardener dry-shake ina haani jannginde ɗum. Aggregat oo ina yaltinee hade mum fuɗɗaade waɗde 3 haa 5 kg/m2 ; ko yaawi kadi ina sinka, ina yaawi kadi ina bonna. Toɓɓere forklift ko dimensiyoŋaaji ceertuɗi. Fiber ina moƴƴina mbaawka punndi, kono teddeendi slab les jolɗe taƴe kuuɓtodinɗe waawaa soodeede caggal e doseeji ; 150 mm ina ɓadii tawo keerol les kammu ton joy, kala ko ɓuri ɗum tiiɗde ina haani ɓuuɓnude nokku walla ɓuuɓnude njamndi. Floors ina keɓa walla ina ŋakkiraa e dow laylaytol jokkondire, sub-base flatness e balɗe jeeɗiɗi gadane safrude ko ɓuri heewde e doseeji tappirɗe e saak.
