B25 (concrete): iimpawu kunye nokusetyenziswa

Eziphathekayo ibhekisa izinto ezindala zokwakha. Kumbiwa iindawo yokuhlala yakudala on Earth lubonise ukuba ukusetyenziswa yayo ngaphezu kwe-6 ezingamawaka kwiminyaka eyadlulayo. Kwaye ngoku yeyona ixhaphakileyo izinto zokwakha. Makhe sihlolisise ngokweenkcukacha enye kwiintlobo zayo - B25-eziphathekayo.

Izinga eziphathekayo

Eyona iphambili lwezalathisi eziphambili wobunjani ikhonkrithi na amandla compressive. Le ichaza udidi eziphathekayo iimpawu aboniswe unobumba "B" (isiLatin), kwaye amanani ehambelana (kg square cm ngalinye), umthwalo kwenxiwa kuyo. Ngenxa yoko, Class B25 eziphathekayo uyakwazi ukumelana nomthwalo 25 kg / macala onke. cm. kwezakhiwo ezikhoyo kule klasi kuquka okuza ayakwazi withstanding umthwalo 327 kg / macala onke. cm, okuhambelana uphawu M350 amandla.

workability

Olu phawu kugqiba ukusebenza eziphathekayo xa isetyenziselwe. Ngokungqinelana GOST 7473-94, le uphawu kuchongwa unobumba "P" kunye elipheleleyo ukusuka ku-1 ukuya kwisi-5, siyafana lubuyisela emanzi kunye lukhuni lemizuzwana ngaphantsi kwe-4 kwaza kwavela ukuwa. Kule Ukudodobala yi (ngokweesentimitha) 1-4, 5-9, 10-15, 16-20 nangaphezulu 21 izitampu ukusuka P1 ukuya P5, ngokulandelelana kwazo.

enkulu isicelo

B25 eziphathekayo (M350 brand) ithandwa kakhulu kwiminyaka yakutshanje, nto leyo ibangwa ngokuqinisa kweemfuneko iiprojekthi kunye nokwandisa ulawulo phezu lawo. Yiloo nto ke, ngenxa yokuba brand baqalisa ukuhlala-manani aphezulu indawo on yokuthengisa imveliso eziphathekayo.

amandla neempawu High inika inani wobunjani zesamente kwi B25 izinto ukubunjwa (concrete). Ngoko ke, lo nto kakhulu esebenzayo kummandla izakhiwo multi-ezinemigangatho, kuba ukwenziwa kwezakhiwo eziphathekayo kakhulu wayigxininisa ngakumbi (imiqadi, Iizilebhu, imihlathi), ebalwa kuquka ukusebenza kwiindawo ngqwabalala.

In yayo concrete ukubunjwa-B25 iindidi iquka, ukongeza kukungciba, inyengane igrabile okanye ilitye nakhandiweyo, wahlamba isanti umlambo. Kwimarike zezixhobo zokwakha zinoku-odolwa kunye kwi ngabenzi, ngabenzi eziphathekayo ngohlobo ekuthiwa-olulungilyo lwe-Mix ezinokwakheka P2-P4 ukuhamba.

B25 eziphathekayo (M350 Brand) luphawulwa amaxabiso aphezulu yezalathi yokuxhathisa iqabaka kunye nokumelana amanzi. Ngoko ke, oko isetyenziswa ngokubanzi nihombisa eqinileyo iziseko (of esityeni, columnar, mfumba-rostverkovyh kunye tape), kwakunye kwizinyuko eziphathekayo. Kulo kumakhaya zabucala (nakwicandelo mveliso) ezi zitya isitya ekutyhidweni, Iizilebhu monolithic neendonga. B25-ikhonkrithi ixesha elide kakhulu yaye ukumelana lingonakali. Ukususela kule uphawu, ingakumbi, indlela wenza indiza iipleyiti esebenza phantsi kweemeko zemozulu nzima kakhulu. Xa zokwakha zorhwebo kubhaliwe kwakhona isetyenziswa ngokubanzi ngenjongo ukuqinisekiswa kwandisa ukuthembeka izakhiwo kunye nezinye izibonelelo.

B25 eziphathekayo: Ixabiso

Le grade iindleko eziphathekayo phantsi kweemeko zangoku sahlukile kubavelisi uluhlu kunokuba olubanzi. Kuxhomekeke kwizinto ezifana nokuba kufutshane emifanekisweni eqingqiweyo, imithombo zempahla ekrwada kunye nempahla yabathengi, yokugcina wakhe, ezothutho kunye norhwebo kunye nesiseko busebenzisekayo, ekugqibeleni, isidima umenzi yemarike zokwakha. Kwakhona Iindleko zixhomekeke iqondo nokushukumisa concrete: eliphezulu oko kukuthi, izinto ezibiza kakhulu. Ixabiso kunye kuyahlukana nedlela amacandelo fillers. eziphathekayo ngenxa zegrabile Ngokuqhelekileyo eyona ndlela yongayo ngaphezu umbandela esekelwe Nyengane batyumke. Enye izinto ingabizi ukusuka inkunkuma erisayikilishiweyo, elifunyenwe besila izakhiwo eziphathekayo. Kwi-avareji, B25-ikhonkrithi zingathengwa (ngaphandle ukunikezelwa) ngexabiso engange 3,000 ukuya 3,800. m ^{3 ngalinye.}

yenza wena

Kwiimeko apho imfuno yent- B25 ezincinane, ikhonkrithi singenziwa ngokwabo. Ukulungiselela le njongo kuyimfuneko ukuxuba nesamente, isanti kunye isikhombisi kwi olinganise womthamo zilandelayo: isamente M500 - 1: 1.9: 3.6; kunokomeleza M400 - 1: 1.5: 3.1. Amanzi zafakwa imali ukuze ufumane ngqongqo oyifunayo. Kuyimfuneko ukuba ukulandela eminye imithetho:

• asebenzise izixhobo kunye namanzi acocekileyo;
• ukusetyenziswa ngcono zesanti wahlamba, amahlalutye okanye ilitye nakhandiweyo (ubumdaka ngodongwe ziyakwehlisa ngokubonakalayo inqaba material);
• Musa ukufaka amanzi lo gama axovula isisombululo (amandla xa idityaniswe elahlekile amanqaku);
• isisombululo kufuneka lusebenziswe ngaphakathi iyure enye emva kwamalungiselelo.

Le lokufaka zinokusetyenziswa igrabile, emphefumlweni lenyengane eweni, lekalika okanye aphakamileyo. Kuba brand eziphathekayo M350 ukusebenzisa fillers ezifana ngodongwe eyandisiweyo, zeBlack kunye nezinye rock aneentunja, ukuba musa ukunika amandla efunekayo ngezinto.

Ngenxa yoko, kweli nqaku sibheke ulwazi malunga iintlobo eziphathekayo, eyona luncedo iindawo zokusebenza kunye nokwakha eliphezulu namandla. Siyathemba ukuba ingcaciso ekule kweli nqaku liza kuba luncedo kuwe.
