Yeklasi eziphathekayo - iimpawu kunye nomahluko

Isiseko - isiseko nasiphi na isakhiwo ukuba sakhiwe. Ngenxa yoko, i ngcono ukuba ndicinge phandle aze abulawe, ngoko ke ezinzile ixesha elide ngakumbi. Izixhobo apho isiseko eliphalalela, nefuthe elivakalayo ubulunga bayo. Ngoko ke, kukho imfuneko ukuthetha ikhonkrithi, ukugqiba udidi eziphathekayo kunye brand yayo.

Isiseko isiseko nto eziphathekayo. Kuyinto ummeli yamandulo izinto zokwakha. Eziphathekayo - uhlobo ngomxube macandelo alandelayo: Umatshini - isamente (Portland isamente kunye zeBlack isamente), amanzi, ecikizekileyo (intlabathi) kunye aggregate yomgrayo (ilitye eyaphukileyo, uhlalutye).

Eyona engundoqo kunye nomgangatho engundoqo pokazatelemi ingqalelo iklasi eziphathekayo nebakala eziphathekayo. Brand ephawula umlinganiselo zesamente ibandakanyiwe umxube eziphathekayo.

Iintlobo yeklasi eziphathekayo ziquka: B10, B15, B20, B25, B30, B40, B80, V12,5, B7.5, V22,5, B35 .... Kule ndawo zilandelayo iintlobo B7.5 - B40.

Kukho somhleli phezu amandla compressive, leyo ixhomekeke lexinene i eziphathekayo :

• M400 - M1000 - enzima kunene;
• M100 - M600 - enzima;
• M50 - M400 - eqhelekileyo;
• M25 - M200 - lula;
• M4 - M100 - ultra-ukukhanya.

Ezi iintlobo zidla kakhulu kusetyenziswa. Digital, nto leyo ifumaneka emva kokuba unobumba M, i ityhubhu amandla compressive, apho zifike emva kweentsuku 28 lokuvuthwa. Kukho kwakhona zibaluleke ngokulinganayo umgangatho eziphathekayo, ezifana: ukuxhathisa njengeqabaka, ukumelana neemeko ndlongondlongo.

Umgangatho kunye nebakala ngekhonkrithi kuba isiseko ixhomekeke ngokupheleleyo injongo, uhlobo kunye nokuxhatshazwa ngakumbi. nempembelelo ebalulekileyo ngokusetyenziswa kweentlobo ezahlukeneyo kwimixube kufuneka iimeko zemozulu zendawo.

Ingqalelo kufuneka anikwe kwi kwisiseko isixhobo kwi parameters zilandelayo:

1. Ezinqamlezayo, umthwalo longitudinal kunye nomthwalo ukusuka ubunzima kwabafileyo.
2. Bhalani lihlolisisa lomhlaba komhlaba.
3. Ubeko lwe indawo, apho ibekwe ngezantsi inqanaba yomgangatho kumgangatho wokuqala, uhlobo sesiseko kunye wangaphantsi uhlobo.

Zonke ezi zinto zichaphazela kakhulu eklasini eziphathekayo, kwakunye neempawu zawo emzimbeni nobomatshini. Ngexesha kwakhiwa isakhiwo yokugcina, ukusetyenziswa zoshishino okanye zokuhlala kuyimfuneko ukwenza ekubalweni imilinganiselo yonke imithwalo.

Ukuze sisiseko ngazo indlu leyo eyakhelwe, waqina, kufuneka kwibakala ukhetho lasekunene ngekhonkrithi kuba isiseko kunye lokufaka. UMarko kuxhomekeke isakhiwo sakhiwa, kokukhona ixabiso umthwalo, kokukhona lophawu, siyavuma.

Ukusuka zingasentla, kucacile ukuba UKOMELELA lolwakhiwo kuxhomekeke mortgaged phantsi isiseko salo, kunye nomgangatho yayo ixhomekeke olinganise kubahlali eziphathekayo.

Ukupheka izinga lakho eziphathekayo lubiza kakhulu: Ngenxa ubunzima ekufumaneni umgangatho ezinqwenelekayo ebambekayo yimiqulu kwi formwork, ezakuphumezwa ngosuku olunye.

Iimposiso kule ekulungiseleleni umxube eziphathekayo afanelekileyo isiseko, unako kakhulu akuphazamisi umgangatho wabo, nto leyo kwixesha elizayo kunokubangela eziliqela iziganeko ezibi. Nokuba kuba yabucala indlu Amalungiselelo loseko kufuna ngenyameko balandela nesithethe ekwakheni yoluntu.

Kubalulekile ukuba ukhumbule ukuba kufuneka ukuba ukukhetha uhlobo ilungelo ngekhonkrithi, ezinye zazo zikulungele ukwakhiwa kwezakhiwo ezinkulu, ngoxa abanye baya kuba nako ukumelana uxinzelelo kuphela izinto ezincinane.
