Grade amandla eziphathekayo: Iintlobo, iimpawu. Grade wamandla eziphathekayo - GOST

Le mbono "kwiklasi eziphathekayo" yaqaliswa ngo-1986 Eli nani limisela Lubalasele umbandela, njengoko amandla eqhelekileyo. Nangona kunjalo, kuba wayekho phambi kokuba ingqiqo uphawu wavumela GOST26633-91 kude.

Njani na brand

Brand ikhonkrithi -. Iityhubhu amandla Compressive ukusuka isisombululo kunye ubude ngohlangothi-15 cm ngaphambi kokuqala kovavanyo ukuba ziyahlala kwiintsuku 28 phantsi kweemeko ngumsindo. Xa ugalela iityhubhu eziphathekayo onencula efunekayo ukususa amaqamza. Iziphumo amandla compressive isondezwa phantsi. brand elinyuliweyo yeleta "M". Okulandelayo oyintsobi ebonisa cube amandla kgf / cm ^2. Ngamanye amaxesha, endaweni yokuthatha iityhubhu umbhobho sangqa-15 cm kunye ukuphakama-30 cm. GOSTS ukuba ezinye ubungakanani isampula. Nangona udidi eziphathekayo ibonakalisa Isalathisi amandla zisezantsi (kunye impazamo kunokwenzeka ka-13.5%), nesitampu ubonisa avareji kuphela.

Ziziphi brand of eziphathekayo wafumana amandla

Okwangoku, i-brand eveliswe yi-M50 ukuya M1000. Le isakhiwo eziqhele ukusetyenziswa eziphathekayo M100-M350. Xa umntu wendlu-isakhiwo kucingwa ukuba M300 kakhulu zithandwa.

Yiloo ndlela ingasetyenziswa iintlobo ezahlukeneyo amandla ngesamente:

• M100 ayikho ingakumbi irobust ezongeziweyo, lisetyenziswa kuphela ukulungiselela imigodi lo kuchithwa isiseko. Maxa wambi isetyenziswa Umatshini sokunikela kerbstones.
• M150 enokusetyenziselwa screeds floor, ewagalela driveways kwaye bathulula kweziseko kwizakhiwo ezincinane.
• M200 lisetyenziswa ulwakhiwo imfumba kunye nomhlaba phantsi kwe tape indlu. Kwaye usebenzisa yona ukwenziwa nobhazabhaza neendledlana kunye namaqonga.
• M250 isetyenziselwa isixhobo umhlaba ngakumbi ethembekileyo ngaphantsi kwendlu.
• M300 - njengokuba sele kukhankanyiwe, le ezininzi eziqhele ukusetyenziswa grade eziphathekayo. Esetyenziselwa ngokugalela iziseko, slab imigangatho, ulwakhiwo Ukubiya.
• M350. Isebenziselwa kwakufunjwa udonga monolithic, imiqadi, iintsika nemàbhula. Banga oluhambelana kakuhle ukwakhiwa nezitya zokutshiza. Kungenxa eziphathekayo zenziwa ngenxa komcu moya.
• Of M400 uphawu lwe ngekhonkrithi eyenziweyo iibhulorho, ibhanki isefu kunye t. D. In the ethile ukwakhiwa kwezindlu ezinjalo lisusiwe ngenxa yeendleko eziphezulu.
• M450-500 kuyasetyenziswa kulwakhiwo iibhulorho, amadami, amatonela, amadami.

iiklasi eziphathekayo

iklasi eziphathekayo - nesalathisi yechaneke ngaphezulu. Oku otyunjwe ileta "B". Lo mzobo ubonisa xi emva kwayo, nto leyo ukumelana umbandela e MPA, ukuya kwi-95%. uluhlu Full ezisetyenziswa kushishino kunye zokwakha iiklasi 3.5-80 eziphathekayo. Okulandelayo, sinikela ingqalelo kwitafile encinane imbalelwano iiklasi kunye namabakala kakhulu ethandwa:

Ukususela oko kuxhomekeka amandla eziphathekayo

iklasi Amandla nebakala ngekhonkrithi kunokuxhomekeka imiba eyahlukeneyo. Umgangatho umxube iphenjelelwa ezahlukeneyo iparameters. Okokuqala konke oko kukuthi, Kakade ke, inani zesamente kunye lokufaka. I elikhulu yowokuqala, ngaphantsi kuneyesibini, imveliso eyomeleleyo ukufumana manzi. Ngenxa isikhombisi kwi zombini zokwakha abucala noshishino ngokuqhelekileyo kusetyenziswa isanti. amandla eziphathekayo kuxhomekeke kuquka ngokobunjani bayo. Obala le excipient, kokukhona ke ngezantsi. Kakade ke, ngenxa yobugorha eziphathekayo ichaphazela uhlobo oluthile lwesamente. Izinto ezinokuthi kukhokelela ekuncipheni umgangatho eziphathekayo, ingaba:

• phambi ngomxube organic ukungcola;
• ubukho kumacandelo eluthulini;
• elimsulwa nobumba.

Ngaphezu koko, amandla yesisombululo kuxhomekeke kubungakanani amanzi inokongezwa kuyo. Ngaphezu kwayo ezincinci, kokukhona umthwalo kwi nomakwenziwe bangamelana. Le nto ukuba amanzi agqithisileyo ekhokelela kuseko kwi obubambekayo inani elikhulu pores. Ezi maqamza nokunciphisa ngamandla alo.

Enye into eziphembelela isakhono eziphathekayo ukumelana ucinezelo kunye ukukhuliswa ngesidanga ukufana lo mxube. Owona mfanekiso robust zifunyenwe ukuba isisombululo ilungisiwe ngokusebenzisa izixhobo ezizodwa. Ezimele yokwakha indlu yokuxovulela lidla eyenziwe sokuxuba lwesamente encinane. Amandla lobume eziphathekayo kwakhona ukwanda vibropressing umxube wabeka.

Uqine amandla olungundoqo kwempixano

Umlinganiselo uhlobo le eziphathekayo kunye namandla - kukuthi, njengoko kuchaziwe apha ngasentla, ukukwazi ubuso ityhubhu kunye cm 15 ukumelana umthwalo compressive, ochazwa kgf / cm ^2. Inyaniso yokuba inani ekwakhiweni eziphawuleka kakhulu. Emva izakhiwo eziphathekayo ngokuqhelekileyo athwale naliphi na umthwalo ngaphezulu. Imizekelo beentanda wamatye iindonga, iintsika neziseko bhanti, inkxaso imihlathi, njalo njalo. D. Noko ke, ngamanye amaxesha kuyimfuneko ukwazi uqine of ebambekayo uqine. Ngokomzekelo, xa kusakhiwa lamatanki, izisele zefula okanye nezadunge. Eli nani ukuba ikhonkrithi Kudla ngokungabikho phezulu kakhulu. Le nto uwaphule kakhulu lula. Yiyo loo nto ngamanye amaxesha ngexesha Inkitha entwasahlobo wavuleka iziseko neendonga, njengoko uxinzelelo phezu kwabo ukusuka ezantsi kunye namacala ngokulinganayo. Ukwandisa amandla kulwandiso wezifundo. uqine lulwandiso efanayo phantse onke amabakala yonke ebambekayo yi-15 kg / cm ² ngesantya zesamente kg 300 / ^m3.

Indlela ukukhetha uhlobo eziphathekayo

Xa ukuyila zonke izakhiwo amacandelo kufuneka banikwe kwibakala elifanelekileyo wamandla eziphathekayo. GOST and isniphu - le nto kufuneka ukukhokela ukhetho. Kakade ke, xa self-zokwakha kuyimfuneko ukuze kube nokugqitywa kanye xa omnye okanye olunye uhlobo lwe ngekhonkrithi kuba kakhulu yingxaki. Indlela elungileyo ukuphuma meko ube kokubonisana yincutshe. Nangona kunjalo, iinkosi ngeglasi izakhiwo eziphathekayo ngokwazo, kwilizwe lethu ngokwaneleyo. Ngoko ke, umbuzo ukuxuba indlela Ukuhlanganiswa ekunene, kwiimeko ezininzi, ingxaki ethile akujongwa. Ngokomzekelo, kuba ulwakhiwo kumhlaba litye lesiseko obuvelisa amandla elungileyo kwi isabelo olusithabazi sisombululo ngokuqhelekileyo kusetyenziswa isamente M400, isanti umlambo kunye ubugoxo ohluzwe ngendlela 1h3h5 ratio. Malunga olinganise ngaxeshanye baxovula usebenzisa endaweni zegrabile enkwalini ngamatye.

Esi sakhiwo zingasetyenziswa iintlobo ezahlukeneyo brand bamandla eziphathekayo. Khetha ilungelo - kuthetha ukuqinisekisa ukuthembeka eliphezulu kwaye ihlala ezakhiwe kuyilo. Umlinganiselo zesamente / Isanti kufuneka ukuba ufumane uhlobo oluthile ikhonkrithi, inokufumaneka iitafile ezizodwa. Ukuze ufumane kubo akunzima, ulwazi umnatha eninzi.
