Kev tsim vaj tsev yog ib qib uas nyuaj tshaj plaws thiab tseem ceeb tshaj plaws hauv kev tsim kho thiab kho dua tshiab. Qhov tshwm sim ntawm kev tsim kho yog nyob ntawm qhov ua tau zoo, txawm tias nws tau nchuav lub hauv paus ntawm lub tsev, txhim kho hauv pem teb lossis txhim kho npog lossis hauv pem teb.
Ib qho tseem ceeb tshaj plaws ntawm kev ua vaj tsev, tsis muaj qhov uas nws tsis tuaj yeem xav txog tus txheej txheem nws tus kheej, yog cov cement-sand mortar . Tab sis nws zoo li ntawd ua ntej. Niaj hnub no, tsis muaj qhov xav tau rau nws, vim tias muaj cov khoom siv tshiab thiab niaj hnub no, qhov zoo thiab cov yam ntxwv ntawm yam uas tsis zoo dua. Peb tab tom tham txog cov xuab zeb ntawm M500 hom. Nws yog hais txog qhov sib xyaw ua ke dawb-ntws tsim kho uas yuav tham txog hauv kab lus.
Nws yog dab tsi?
Kev sib xyaw ntawm cov xuab zeb ua ke ntawm M500 hom suav nrog tsuas yog cov xuab zeb, pob zeb ua ke thiab ntau yam hloov kho. Cov khoom loj xws li pob zeb tawg, pob zeb lossis nthuav av nplaum tsis nyob hauv nws . Qhov no yog qhov txawv nws los ntawm cov qhob zoo tib yam.
Tus tuav yog Portland cement.
Qhov sib xyaw no muaj cov yam ntxwv hauv qab no:
- qhov loj tshaj qhov me me yog 0.4 cm;
- tus naj npawb ntawm cov khoom loj - tsis ntau dua 5%;
- ntom coefficient - los ntawm 2050 kg / m² txog 2250 kg / m²;
- noj - 20 kg rau 1 m² (muab tias txheej tuab tsis tshaj 1 cm);
- kev siv kua rau 1 kg ntawm cov sib tov qhuav - 0, 13 litres, rau 1 lub hnab ntim sib xyaw hnyav 50 kg ntawm qhov nruab nrab 6–6, xav tau 5 liv dej;
- tus nqi ntawm kev daws teeb meem, thaj chaw sib tov - txog 25 litres;
- lub zog - 0.75 MPa;
- te tiv taus coefficient - F300;
- dej nqus coefficient - 90%;
- cov txheej txheem pom zoo tuab yog los ntawm 1 txog 5 cm.
Ib qhov chaw ntim nrog cov xuab zeb ua kom tawv tawv tom qab 2 hnub, tom qab uas nws tuaj yeem tiv taus cov khoom hnyav . Nws kuj tseem tsim nyog sau cia qhov tsis kam ntawm cov khoom siv rau qhov kub heev. Kev teeb tsa ua haujlwm siv cov xuab zeb ua haujlwm tuaj yeem ua tiav ntawm qhov kub thiab txias ntawm -50 txog +75 ºC.
Cov xuab zeb ua ke ntawm M500 hom yog ib qho khoom siv zoo tshaj plaws thiab txhim khu kev qha tshaj plaws rau kev teeb tsa thiab tsim kho ua haujlwm uas muaj nyob niaj hnub no. Nws muaj tus lej ntawm cov yam ntxwv, ntawm qhov nws tsim nyog sau cia:
- siab zog, hnav tsis kam;
- corrosion kuj;
- yam tsawg shrinkage;
- homogeneous qauv ntawm cov khoom, muaj kev xyaum tsis muaj qhov hws hauv nws;
- siab yas;
- siab coefficient ntawm Frost tsis kam thiab dej tsis kam;
- yooj yim ntawm kev npaj thiab kneading.
Raws li qhov ua tsis tau, nws yog kev khuv xim, tab sis lawv kuj muaj. Theej, ib qho, tab sis tseem ceeb heev - qhov no yog tus nqi. Tus nqi rau cov xuab zeb ua ke ntawm M500 hom yog siab heev . Tau kawg, cov cuab yeej thiab lub cev thiab kev ntsuas tsis zoo ntawm cov khoom siv tau ua pov thawj nws, tab sis tus nqi xws li tsis suav nrog qhov muaj peev xwm siv cov khoom siv hauv lub neej niaj hnub.
Scope ntawm daim ntawv thov
Kev siv cov xuab zeb ua ke M500 muaj feem cuam tshuam hauv kev tsim khoom lag luam, nyob rau qhov xwm txheej uas txhua qhov chaw thiab cov txheej txheem ntawm lub tsev lossis cov qauv uas yuav tsum tau tsa yuav tsum muaj lub zog siab. Nws yog siv thaum lub sijhawm teeb tsa:
- sawb lub hauv paus rau cov tsev, qhov siab uas tsis pub dhau 5 plag tsev;
- qhov muag tsis pom;
- phab ntsa-nqa cov kabmob;
- choj txhawb nqa;
- cib ua haujlwm;
- txhawb rau cov qauv hydraulic;
- paving slabs;
- phab ntsa thaiv, monolithic slabs;
- muaj zog hauv pem teb screed (cov plag tsev ua los ntawm M500 cov xuab zeb ua hauv cov chaw nres tsheb, cov chaw yuav khoom thiab lwm qhov chaw uas muaj tus yam ntxwv zoo ib yam).
Raws li koj pom qhov kev thov ntawm cov khoom siv hauv tsev no yog qhov dav heev thiab sib txawv … Feem ntau hom khoom siv no yog siv rau kev tsim cov qauv hauv av, xws li cov chaw nres tsheb hauv xov tooj cua.
Cov xuab zeb zeb M500 tsis yog tsuas yog cov khoom siv muaj zog heev, tab sis kuj muaj qib siab ntawm kev co tsis kam, uas ua rau nws siv tau tsis tsuas yog hauv av, tab sis kuj nyob hauv nws.
Cov xuab zeb sib xyaw ua ke tsis tshua muaj siv hauv kev tsim kho ntiag tug . Qhov no yog, tau kawg, vim tias tus nqi siab ntawm cov khoom siv hauv tsev thiab nws lub zog siab. Yog tias nyob ib puag ncig ntawm lub tsev ntiag tug muaj qhov xav tau los tsim tsev ib-zaj dab neeg lossis cov qauv ib ntus, tuaj yeem siv cov qib qis dua.
Yuav siv li cas?
Cov xuab zeb zeb muag hauv hnab. Txhua lub hnab hnyav 50 kg, thiab ntawm txhua lub hnab, cov chaw tsim khoom yuav tsum qhia qhov cai thiab qhov sib npaug rau kev npaj cov khoom sib xyaw rau nws siv ntxiv.
Txhawm rau kom tau txais kev sib xyaw kom zoo, koj yuav tsum tau soj ntsuam cov feem thiab ua raws cov lus qhia:
- ncuav txog 6-6.5 litres dej txias rau hauv lub khob;
- qhov sib xyaw ua ke tau maj mam ntxiv rau hauv dej me me;
- Nws yog qhov zoo tshaj plaws los sib tov cov tshuaj mortar siv cov khoom sib xyaw ua ke, kev sib xyaw ua ke lossis cov laum nrog cov ntawv tshwj xeeb.
Cov tshuaj ua tiav "xuab zeb ua ke M500 + dej" yog qhov zoo tshaj rau qib hauv pem teb thiab phab ntsa. Tab sis yog tias nws yog qhov tsim nyog los ua lub hauv paus lossis txhim kho cov qauv, nws tseem tsim nyog ntxiv cov pob zeb tawg.
Nws cov feem yuav tsum yog qhov tsawg tshaj plaws, thiab ua tau zoo tshaj plaws.
Raws li kev txhawj xeeb txog dej, muaj ib txoj kab nqaim heev ntawm no, uas tsis muaj leej twg tuaj yeem hla tau. Yog tias koj ntxiv dej ntau dua qhov koj xav tau, cov tshuaj khib yuav poob nws lub zog vim tias cov dej noo tso cai tau siab dhau . Yog tias tsis muaj kua txaus, saum npoo yuav kis tau.
Kev npaj ua av xuab zeb ua ke yuav tsum tau haus tsis pub dhau 2 teev tom qab npaj. Tom qab lub sijhawm no, cov tshuaj yuav plam nws cov yas. Kev siv ib 1m2 nyob ntawm seb hom haujlwm thiab tuab ntawm txheej txheej thov.
