1. Amabwera mu mawonekedwe amadzimadzi kapena ufa. Ogwira ntchito amawawonjezera mwachindunji ku galimoto ya konkire kapena makina osakaniza. Kuchuluka kophatikizidwa ndi kochepa. Nthawi zambiri amangokhala ochepa peresenti ya kulemera kwa simenti. Koma chiwerengerochi chimapangitsa kusiyana kwakukulu.
2. Zosakaniza zimakonza zovuta zanthawi zonse. Mwinamwake konkriti imafuna kuyenda bwino kwambiri pafupi ndi rebar yolimba. Mwina iyenera kukhazikitsidwa mwachangu pa tsiku lozizira. Zosakaniza zimapangitsa kuti zosinthazi zikhale zotheka. Ndi zida zofunika kwambiri pomanga masiku ano.
3. Pali mitundu yambiri. Mtundu uliwonse umayang'ana malo okhala konkriti. Zochepetsera madzi zimapangitsa kusakaniza kuyenda bwino kwambiri popanda madzi owonjezera. Ma Accelerator amafulumizitsa nthawi yokhazikitsa. Ma retarders amachepetsa. Ma air-entrainer amaphatikiza tivuvu tating'ono ta mpweya tozizira kukana kusungunuka. Plasticizers amawongolera magwiridwe antchito. Mndandanda ukupitirira.
4. Kugwiritsa ntchito admixtures kumafuna chisamaliro. Muyenera kutsatira malangizo a distributor. Kusakaniza nthawi ndi dongosolo. Kuphatikizira mochulukira kungakhale koyipa kuposa kuwonjezera ayi. Kuphatikizika kolondola kumatsimikizira kuti kuphatikiza kumagwira ntchito moyenera.
5. Iwo si m'malo kwathunthu konkire njira. Zogulitsa zabwino komanso kuchiritsa koyenera ndizofunikirabe. Zosakaniza zimawonjezera njira zabwino kwambiri. Sachita ndi zoipa. Ganizirani za iwo monga othandizira, osati anthu onyenga.

Chifukwa Chake Muzigwiritsa Ntchito Konkire Zosakaniza? .

Bwanji mukuvutikira ndi mankhwala owonjezerawa? Ubwino wake ndi woonekeratu. Amapangitsa konkriti kukhala kosavuta kugwira ntchito. Iwo amawonjezera khalidwe lapamwamba la chinthu chomaliza. Amapulumutsa ndalama ndi nthawi.

1. Kuchita bwino kwambiri ndi chinthu chachikulu. Konkriti imafuna kuti ikhale yosavuta kuyikapo ndikuyika. Kuwonjezera madzi ambiri kumapangitsa kuti madzi aziyenda bwino kwambiri. Koma madzi owonjezera amawononga konkire. Zosakaniza zochepetsera madzi zimagwiritsa ntchito mwayi. Amalola konkire kuyenda bwino popanda kufooketsa. Ogwira ntchito atha kuyika konkriti mwachangu komanso mosachitapo kanthu.
2. Kuwongolera nthawi yokhazikitsa ndikofunikira. Taganizirani za tsiku lotentha lachilimwe. Konkriti ikhoza kukhazikikanso mwachangu. Ogwira ntchito amavutika kuti amalize bwino. Kusakaniza kwa retarder kumachepetsa izi. Zimapereka nthawi yochulukirapo yoyika ndi kumaliza. Mosiyana ndi zimenezo, m'nyengo yozizira, accelerator imathandizira kusonkhanitsa konkire mwachangu. Izi zimateteza ku kuwonongeka kozizira.
3. Kukhazikika kokhazikika ndikofunikira kwambiri. Konkire amakumana ndi adani ambiri. Kuzizira ndi kusungunuka kumatha kuswa. Mankhwala monga mchere wa deicing amagunda. Zosakaniza zolowetsa mpweya zimatulutsa tinthu ting'onoting'ono ta mpweya. Ma thovu amenewa amapereka madzi kuti afutukuke akaumitsidwa. Izi zimasiya kusweka.

Ndendende momwe Mungasankhire Zosakaniza Zoyenera? .

Kutola sikutanthauza kupeza mtundu uliwonse wa botolo. Muyenera njira. Kusakaniza koyenera kumadalira kwathunthu ntchito.

1. Nenani zomwe polojekiti ikufunika poyamba. Ndi zovuta ziti? Kodi ndikuyika konkire mumtundu wovuta? Ndiye kugwirira ntchito kwakukulu ndikofunikira. Ndi malo okwera pamalatho omwe amakumana ndi nthawi yachisanu? Ndiye kukana kuzizira kumafunika. Mwinamwake slab iyenera kukhala yokonzekera kuyenda kwapaintaneti mofulumira. Ndiye kukhazikitsa mwachangu ndikofunikira. Lembani otsogolera 2 kapena zofunikira zitatu zogwirira ntchito.
2. Zindikirani mikhalidwe ya chilengedwe. Kutentha kumagwira ntchito yaikulu. Kutentha nthawi zambiri kumafuna ochedwetsa. Zima nthawi zambiri zimafunikira ma accelerator. Kuchuluka kwa chinyezi kumakhudza kukhazikitsa nthawi. Mavuto amphepo amatha kuumitsa pamwamba mwachangu. Sankhani zosakaniza zomwe zimayankha zotsatirazi.
3. Dziwani kalembedwe ka konkire. Mtundu wa simenti ndi wofunika. Ma konkriti ena amachita mosiyana ndi zosakaniza zina. Kuchuluka kwa madzi, mchenga, ndipo miyala imakhudza momwe admixture amachitira. Cholinga cha slump chimatsogolera njira yochepetsera madzi kapena plasticizer. Gawani mapangidwe osakaniza ndi ogulitsa admixture.
4. Funsani admixture distributor mwamsanga. Iwo ndi akatswiri. Kambiranani zachindunji cha polojekiti. Adziwitseni tsatanetsatane wa kalembedwe. Lankhulani za nyengo. Pemphani zowatumizira. Akhoza kulangiza mtundu wabwino kwambiri ndi mlingo. Akhoza kulangiza za mikangano yomwe ingakhalepo.
5. Kufufuza, kufufuza, kufufuza! Osadalira kusatsimikizika. Pangani seti zoyeserera pogwiritsa ntchito zida zenizeni. Unikani konkire yatsopano. Yang'anani momwe ntchito yake ikuyendera komanso nthawi yokhazikitsa. Yesani konkriti yolimba kuti muwone kulimba ndi kulimba. Tsimikizirani kuti zosakaniza zimagwira ntchito momwe mukuyembekezeredwa. Tsimikizirani kuti sichimayambitsa zovuta zilizonse.

Kugwiritsa Ntchito Mitundu Yosiyanasiyana Yophatikiza? .

Ntchito zosiyanasiyana zimafuna mayankho osiyanasiyana. Mtundu uliwonse wa admixture umawala mwatsatanetsatane zochitika.

1. Zochepetsera madzi ndi superplasticizer zili paliponse. Amathandizira kuti pakhale malo osavuta kwambiri. Izi ndizofunikira pakupopera konkriti maiko odutsa. Ndikofunikira kuyika konkriti m'magawo olimbikitsidwa kwambiri. Zomangamanga, milatho, ndi zomangamanga ubwino wonse.
2. Ma Accelerator ndi a kuzizira. Iwo amafulumizitsa kukhazikitsa ndi kulimbikira koyambirira. Agwiritseni ntchito pamene kutentha kwatsika pansi 50 ° F (10 °C). Amathandizira kukonza zochitika zadzidzidzi zomwe zimafunikira kusintha mwachangu. Zomera za konkriti zokhazikika zimazigwiritsa ntchito mwachangu nkhungu ndi mildew.
3. Ma retarders amalimbana ndi kutentha. Amachedwa kulowa m'nyengo yotentha. Izi zimapereka nthawi yochulukirapo yoyika zidutswa zazikulu kapena zinthu zovuta zomangamanga. Amateteza motsutsana ndi zozizira kwambiri m'malo akuluakulu. Agwiritseni ntchito pamene magalimoto a konkire atsekeredwa m'misewu pakatentha.
4. Zosakaniza zolowera mpweya zimateteza ku kuzizira kwachisanu. Iwo kuvomerezedwa konkire pansi kuzizira nyengo ndi madzi. Ganizirani ma driveways, misewu, zopinga, ma bridge decks, ndi madamu. Tizilombo tating'onoting'ono ta mpweya timateteza kuti tisaphwanyike chifukwa cha kukula kwa ayezi.
5. Zosakaniza zapadera zimathetsa mavuto apadera. Kupewa dzimbiri kumatetezanso milatho kapena magalasi oimika magalimoto omwe ali ndi mchere. Zochepetsa kuchepetsa zimachepetsa kung'amba mu zidutswa zazikulu zapansi. Zothandizira zopopera zimathandizira kusuntha konkire bwino pamapaipi aatali. Kuletsa madzi admixtures m'munsi permeability kwa zipinda zapansi kapena akasinja madzi.

Mafunso Okhudza Konkrete Admixtures? .

Anthu nthawi zambiri amakhala ndi nkhawa pazinthu izi. Nazi zina zodziwika bwino.

1. Kodi zosakaniza zimapangitsa konkire kukhala yofooka? Ayi. Kugwiritsa ntchito bwino, ambiri amawapangitsa kukhala amphamvu kwambiri. Zochepetsera madzi zimalola madzi ochepa kwambiri, kumabweretsa kukanika kwambiri. Air-entrainers pang'ono m'munsi kulimba. Koma kunyengerera kwa chitetezo chachisanu-thaw ndikoyenera. Nthawi zonse tsatirani miyezo ya mlingo.
2. Ndi admixtures okwera mtengo? Mtengo pa kiyubiki imodzi nthawi zambiri umakhala wocheperako. Nthawi zambiri madola angapo. Yerekezerani izi ndi ubwino wake. Kuchepetsa mtengo wa ntchito, kupulumutsa nthawi, apamwamba kwambiri, ndi kuchepetsa ntchito zokonza. Kubwezera kumakhala kwakukulu.
3. Kodi ndingathe kuphatikiza zosakaniza zosiyanasiyana? Nthawi zambiri ndithu, nthawi zambiri ayi. Zosakaniza zina zimagwira ntchito bwino wina ndi mzake. Ena akhoza kukangana. Mwachitsanzo, kuphatikiza retarder ndi accelerator nthawi zambiri amathetsa izo. Nthawi zonse lankhulani ndi wogulitsa. Gwiritsani ntchito zinthu zomwe zimagwirizana kuchokera kwa wothandizira yemweyo makamaka.
4. Will admixtures zimakhudza mthunzi wa konkire? Zosakaniza zofala kwambiri zilibe mphamvu. Ndi madzi oyera kapena otumbululuka. Zina zochepetsera madzi okwera zimatha kukhala ndi mthunzi wocheperako. Izi sizikhudza mthunzi womaliza wa konkriti. Onetsetsani nthawi zonse ngati mthunzi ndi wofunikira.

(Zofunika Kwambiri Posankha Zosakaniza Zosakaniza)

5. Zosakaniza zimasintha njira zabwino zochiritsira? Ayi ndithu! Zosakaniza zimathandizira kuti konkriti igwire bwino ntchito. Komabe kuchiritsa ndikofunikira. Kuchiza kumapangitsa kuti konkire ikhale yonyowa kuti ikhale yolimba bwino. Ngakhale kuphatikiza kothandiza kwambiri sikungathandize konkire yochiritsidwa molakwika. Kuchiritsa koyenera kumapitirizabe kofunika.
