B15 eziphathekayo (TM): ukubunjwa, iimpawu

Eziphathekayo - mhlawumbi izinto zokwakha kakhulu ifuna esisetyenziswa ngokubanzi kwi kulwakhiwo zombini izindlu zabucala kunye nezakhiwo ezinkulu multi-ezinemigangatho. Kukho iintlobo ezininzi zezi zixhobo yosebenziso iintlobo ezininzi ezahlukeneyo. Enye kakhulu ethandwayo lubuyisela B15 (udidi) okanye M200 (TM).

iimpawu ngokubanzi

B15 eziphathekayo (M200 mark) libhekisela kwiqela abanesidanga kwe amandla 196 kgf / cm. Lenziwe kuthathelwa ingqalelo imimiselo ka GOST ngezixhobo mihla imida imveliso ezenzekelayo. Ngenxa yoko izinto kwizinga eliphezulu kakhulu zikulungele ukwakhiwa kwe ezahlukeneyo izinto noshowo kwezakhiwo.

Ububanzi bokusebenzisa

Imveliso strong nokwadala elide - indawo engundoqo isicelo kwalo mbandela. Ukumelana neemeko zemozulu esibi avareji. Kwaye, ngoko ke kungcono ukuba ukusebenzisa ngaphakathi. Screed usebenzisa le nto inika okubambekayo kakhulu ixesha elide. Ukongeza koku, eziphathekayo B15 - lophawu, esetyenziswa:

• yokwakha iziseko (ingakumbi izakhiwo ekhaya);
• ekhupha udonga;
• nokuveliswa yokuhambahamba eziphathekayo kunye esikuthintela;
• eyothi pavings;
• ukwakhiwa izinyuko iiveranda;
• ukwenziwa kweemveliso eziphathekayo precast;
• eyothi imihlathi;
• ukudala le zeendawana ngexesha imisebenzi endleleni.

Mark ikhonkrithi B15: Uqulunqo

Yenza B15 ikhonkrithi eqhelekileyo usebenzisa ziqendwana zilandelayo:

• Cement (30 kg).
• lokubolekwa Small (40 kg). Unako ukusebenzisa isanti kunye ubukhulu bamagaqa mm 0,15 ukuya ku-5. mninzi wayo kufuneka ibe 1790 kg / m ^3.
• ilitye nakhandiweyo okanye igrabile (90 kg). ubukhulu ukhozo lokufaka isusela ukusuka mm-6 ukuya ku-70. Kunye nokwakhiwa kwezakhiwo amakhulu lungasetyenziswa amaqhezu ilitye utyumkile ubukhulu ukuya kwi-140 mm.

components ezomileyo ngaBasebenzi bePri-ixutywe uze exutywe ngamanzi mali ka-20% yabo ngumthamo opheleleyo. Ngamanye amaxesha abenzi ukuphucula umgangatho imveliso ogqityiweyo idityaniswe ukuya kuyo zonke iintlobo izimbiwa, plasticizers, njalo-njalo. D.

Yenziwe le concrete grade B15 (GOST 7473-2010) kuphela ukusuka isamente ezikumgangatho ophezulu. Kaninzi iba imveliso brand M400. Umlinganiselo Ubunzima zesamente * * uhlalutye esanti zobukhulu bekuya kuba: 1 * 2.8 * 4.8.

uhlobo

Okwangoku iintlobo ezininzi ngekhonkrithi eklasini yayo. Bayakwazi zinokwahluka, umzekelo, kuhlobo lokufaka esetyenzisiweyo. Oku ikalika, inyengane igrabile okanye ilitye batyumke. Kukho iintlobo zezi zixhobo zokufunda kunye izidanga ezahlukeneyo ukushukumiseka kunye ukuqina.

Umlinganiselo brand nebakala

Ngokwahlukileyo inkolelo ethandwayo, emva kweentsuku 28 ukuze bafumane amandla ikhonkrithi akayeki. Le nqubo ingathatha onke yokusebenza ixesha esakhiwe kuyilo yakhe. Mark ikhonkrithi uzimisele ngokuxhomekeke kwisixa zesamente ezisetyenziswa imveliso yawo. Esi salathisi idlala indima ebalulekileyo ukukwazi eziphathekayo ukuxhathisa ucinezelo kunye nokwandiswa. Oku ulinganiswa Kum / cm ^3. Ngenxa yoko, nesitampu eziphathekayo M200 ibonisa ukuba uqine xa ucinezelo ka 200 kgf / cm ^3.

Ukongeza lophawu, kwaye nkqu eziphathekayo yahlulwe kwiiklasi. Ngokwale isalathisi imisela xi siphezulu ukwazi ukumelana nezinto ogqityiweyo ngo megapascals. Kulo mba 15 ukuya 15 MPA (95%). Udidi eziphathekayo kakhulu luchazwa yileta "B".

Ngaphambili, xa ngamandla eziphathekayo ndamangalelana ikakhulu brand. Ngoku le nto zihlelwe ikakhulu kwiiklasi. Kodwa abantu baqhele ukuba bajolise kwi-lophawu, kwaba lula ngakumbi, umisele iitafile ezizodwa, anikwe ukufanisa kwezi zalathisi mabini.

Grade of eziphathekayo nakwezinye iimo

Iyahlala - ayikho kuphela parameter apho kufuneka sinikele ingqalelo xa uthenga umxube. Isalathi kubaluleke kakhulu nayo isisombululo ukuba iqabaka brand. Oku otyunjwe unobumba F kunye amanani eqala nge 25 Ekusebenzeni, ngendlela yabucala kwindlu isakhiwo ngokuqhelekileyo kusetyenziswa ezinokwakheka iqabaka brand F100-200.

Enye parameter ebalulekileyo - luvukelo wamanzi eziphathekayo. Kulo mzekelo, i elayibrari kuthi ndiligwala W2, w4, W6, W8 kunye w12. Amanani abonisa ukuba uxinzelelo lwamanzi apho lombhobho eziphathekayo-15 cm ubude ngamanzi noxinzelelo ethile. Eziphathekayo iimpawu B15 uphawu kule nkalo kuhle kakhulu.

Kwakhona, xa uthenga izinto kufuneka sinikele ingqalelo nezalathisi ezifana esasisikhulu. Le parameter acacisa maeriala uphawu nje ukuhamba. "P" kuphawulwa ngesazobe kwiphepha data unobumba umxube. Eyona lisetyenziswa kumaxesha amaninzi ekwakhiweni ezinokwakheka ukuhamba P-2 no P-3. Solutions yenqanaba P-4 nangaphezulu asetyenziswa xa efunekayo ukugcwalisa nzima ukufikelela iindawo. iplastiki elisetyenzisiwe kunye eziphathekayo lwenziwa xa ukulahlwa usebenzisa impompo.

iimpawu technical

Zeziphi iimpawu othile kwahluke B15 eziphathekayo (ibakala M200), zingafumaneka kule theyibhile ingezantsi.

Iindleko zokufunda

Amaxabiso for yeklasi eziphathekayo B15 (M200 Brand) zixhomekeke ikakhulu ntlobo ezisetyenziswayo xa kwenziwa imveliso kuyo ngasese. Umzekelo, ukuba lenyengane, we-cubic metre concrete B15 kuya kufuneka ukuba uhlawule malunga 3.850 engange (ngo-2015). Kuba lwalo luhlalu lokufaka - malunga 3600 p.

Manufacturing ekhaya

Fumana umxube ezikumgangatho ophezulu kulo mzekelo kunokwenzeka, esebenzisa kuphela Umxhubi eziphathekayo. Ngezandla elungileyo concrete udidi B15 brand M200 baxovula ayisebenzi. Inkqubo ukulungiselela isisombululo imi ngolu hlobo lulandelayo:

• isanti ngononophelo pre-ephikisanayo kunye isamente. Kweli nqanaba umntu baluphose additive leyo eyandisa uxhathiso ebandayo (20 kg-2 kg zesamente).
• Okulandelayo, zigalelwe amanzi, uze ke ilitye batyumke.
• Lo mxube ngenxa ivuselelekile imizuzu ezintathu ubuncinane.

Umthamo Umlinganiselo B15 eziphathekayo (grade M200) iphuma olinganise zilandelayo: 10 yeelitha 19 iilitha amkelwe nesanti isamente kunye uhlalutye 33 eelitha. Ngenxa yoko, umlinganiselo iya kuba malunga ezi emele desyatilitrovyh: 1h2h3,5.

Ekwenziweni eziphathekayo olu phawu ukutenxa kwangaphambili ngawona ubungakanani akukho ngaphezulu kwe-1%.

Umzekelo batch

Ukuze kube nokwakhiwa isiseko columnar element volume 0,11 m ³ abakudingayo malunga nama-19 kg nesamente, isanti - 41 kg, uhlalutye eyaphukileyo - 78 kg yamanzi - 9 kg. Le ngokunxulumene sisebenza xa usebenzisa M400 uhlobo oluthile lwesamente. Kwisithuba kufuneka enze malunga ezimbini ukuxuba ezinjalo.

ezinye brand eziphathekayo

rhoqo kakhulu abucala endlwini-isakhiwo esisetyenziselwa kwaye ibanga quality eziphathekayo M250 (B20). Olu hlobo unamandla thile ngaphezu B15 eklasini kwaye zingasetyenziswa kwakhona ekubunjweni Iizilebhu ukuba musa baxinezeleke kakhulu. brand eziphathekayo M300 (class V22,5) ngoyena ngokuqhelekileyo isetyenziselwa ukwakhiwa komcu iziseko. Ukuze ukugcwalisa MDF eqinile phantsi endlwini kaninzi kusetyenziswa M350 isisombululo (udidi B25).

B15 eziphathekayo - amandla lophawu, ngoko ke zikulungele ukwakhiwa bezinto abaninzi abucala ekwakheni indlu. iimpawu processing elungileyo kakhulu, kudityaniswe ixabiso eliphantsi kwenza kube nokwenzeka ukuba ukusebenzisa zombini ukuvala screed kunye nemigangatho, kunye nokwakhiwa iziseko (hozpostroek) kunye zokwahlula.
