Mark ukhonkolo noma ibanga? Kanjani ukuze uhlukanise ukhonkolo ekwakhiweni ekhaya lakho siqu?

Iningi kwezindlu ngabanye libabiza ukhonkolo, lisebenzisa igama ezifana ibanga ukhonkolo. Nokho, le nto isakhiwo has esinye futhi isici - isigaba. Kwaba namuphi ixhunyiwe selectivity enjalo, futhi yini umehluko phakathi uphawu futhi isigaba?

Concretes kuyizinto ezivamile, engenakuqhathaniswa impahla, ukwakha, kanye nokusetshenziswa yesibili, ngemva leso sizinda samanzi emhlabeni. Ingabe i itshe yokufakelwa etholwe, esukela solidification of mass homogeneous elixutshwe ngezabelo ezithile izingxenye ezifana usimende, amanzi, fillers kanye / noma abakhi.

Kukhona inombolo kahle esikhulu ka Concretes ezahlukene ziyehluka enjongweni, futhi ababukeka uhlobo isibopho esiyinhloko kanye fillers - nemibandela yokuvuthwa, futhi isakhiwo yayo. Nokho, naphezu kwakho konke lokhu ezihlukahlukene ukhonkolo, zikhona izici qualitative eziyisisekelo ezintathu kuphela ukuthi asetshenziswa izibalo ekuklanyweni kwezakhiwo esizayo - amandla, ukumelana namanzi kanye ukumelana frost. Ukuze sithole imali lezi ezibaluleke izakhiwo ukhonkolo kanye kwangena nomqondo sha namabanga.

Ngokwesibonelo, kusetshenziswa kakhulu e izindlu ngamanye ukwakhiwa izisekelo ehlukene ukhonkolo ukumaka 200 kungokwalabo ikilasi B 15 futhi frost - F75-F100 futhi waterproof - W2-W4.

Yiqiniso, okokuqala kuphakama umbuzo yini ebangeni ngokhonkolo futhi yini umehluko yayo kusukela ekilasini.

Kumele siqale nge, amakilasi ukhonkolo kanye logo Nokho kukhona kuphela amandla izici, babelemisebenzi eminye imininingwane ehilelekile e ngokoqobo.

amandla Brand kuyinto zifane Inkomba zezinombolo ethathwe zocwaningo nangama amandla compressive. Ngamanye amazwi, ukubaluleka lapho enquma ukuthi esiphezulu umthwalo mechanical zingamelana square isentimitha ebusweni. Njengoba ukhonkolo bathambekele ngokwanda ngokuhamba kwesikhathi, amandla, tivivinyo angaphansi inkomba amasampula (yabalingisi cubes nohlangothi lokuzibona 10 amasentimitha) ngineminyaka engu-nokuvuthwa of izinsuku ezingengaphansi kwezingu-28. Ekhona uphawu ukhonkolo - ku ezahlukene kusukela M800 ukuba i-M50 (nge okwandisa ukuminyana kokwanda ohlwini lwezikhombo kwamanani). Ukuze ukwakhiwa ngabanye alisetshenziswa ukhonkolo ngaphezu kwebanga 400.

Nokho, amandla imangalelwe uphawu inani laboratory, kusukela e umkhuba ithinta oluxhumekeke kungasimamisi ezifana yokuphazamiseka ubuchwepheshe ukukhiqiza, isihlabathi namanzi izinga lokungafani, kanye kulungiselelwa ushintsho laying izimo. Konke lokhu kuholela ukwehla amandla izici. Futhi leli phutha noma Coefficient ukushintshashintsha umehluko oyinhloko phakathi isigaba ngokhonkolo ku brand ayo. Ngokuyisisekelo kungcono nje amandla langempela nge ezincane (5%) ukuphambuka. Ngo umkhuba ekilasini ukhonkolo - i value ezibalulekile ebalisisiwe isetshenziswa (ngokungafani kuya uphawu) ekuklanyweni izitshalo esikhathini esizayo. Ayephila e MPA, futhi ulawulwa GOST 26633-85. Sekukonke kukhona nesithupha amandla amakilasi ezisukela 3.5 ku-60.

Izimfanelo qualitative ezilandelayo - ukumelana namanzi kanye frost ukumelana - ihlukaniswa kuphela emamaki.

Mark ukhonkolo, ephawula frost futhi value laboratory. Limelela esiphezulu zezinombolo inkomba eziningi test lapho isampula yabekwa iqhwa-ncibilika. Frost eziyisishiyagalombili emamaki kunqunywa uhla kusuka 50 F kuya 500 F.

Enye qualitative isici - ibanga ngokhonkolo ku ukumelana namanzi. Ukuze kophawu of ungangenisi amanzi isicelo kwelesithupha ezisukela 12 W ukuba W2, okuyizinto seqiwe yokucindezelwa amanzi lapho amasampula inkomba abakwazi ukudlula kwamanzi (kuncike kwimibandela ukuhlolwa ejwayelekile).
