Mark ikhonkrithi okanye kwibakala? Indlela Cazulula olungundoqo lokwakhiwa kwekhaya lakho?

ababhekisi phambili Uninzi zezindlu ngamnye ngokucalula nokwahlula eziphathekayo, esebenzisa ibinzana ezifana kwibakala eziphathekayo. Noko ke, le zokwakha inomnye uphawu - iklasi. Noko ehlobene selectivity enjalo, kwaye yintoni umahluko phakathi amanqaku kunye eklasini?

Concretes ke, nanto, izinto ziqhelekileyo besakha, kwaye ukusetyenziswa yesibini, emva kokuba resource amanzi ehlabathini. Ngaba i ilitye ngumntu efunyenweyo, ngenxa Ukuqinisa ye ubunzima yohlobo olunye ezixutywe Amanani ezithile amacandelo ezifana isamente, amanzi, fillers kunye / okanye abakhi.

Kukho iqela elikhulu concretes ezahlukeneyo zahlukile kwinjongo, kwaye imbonakalo kunye nohlobo Umatshini eziphambili kunye fillers - kunye neemeko emuncu, nesakhiwo sayo. Noko ke, naphezu kwayo yonke le iindidi ngekhonkrithi, kukho amathathu kuphela iimpawu ezisemgangathweni ezingundoqo esetyenziswa kwi ebalelwe kuyilo lwezibonelelo elizayo - amandla, ukumelana amanzi kunye nokumelana yeqabaka. Ukuze ubone Izixamali zezi ebalulekileyo iimpawu eziphathekayo kunye zaye zaziswa ingqiqo uphawu nebakala.

Umzekelo, zazisetyenziswa kwizindlu ngamnye ukuze kwakhiwe iziseko ezahlukeneyo besebenzisa izinto eziphathekayo uphawu 200 bobabo eklasini B 15 kunye iqabaka - F75-F100 yaye amanzi - W2-w4.

Kakade ke, okokuqala zonke umbuzo yintoni na grade eziphathekayo kwaye yintoni umahluko yalo eklasini.

Kufuneka uqale, iiklasi eziphathekayo kunye namagama kukhona kuphela iimpawu amandla, Noko ke, yiba ezincinane abanye zenziwe ngokuphathekayo.

Brand amandla index wokwamanani zifane zivela iimvavanyo elebhu kunye namandla compressive. Ngamanye amazwi, xabiso lazo elo limisela ukuba umthwalo mechanical ubuninzi ukwazi ukumelana square isentimitha komhlaba. Okwelitye badla amanani ngokuhamba kwexesha, amandla, ezi mvavanyo kuxhomekeke iisampulu reference (iityhubhu uphose kunye icala ngeesentimitha eziyi-10) xa eneminyaka nokwanda, elingekho ngaphantsi kweentsuku ezingama-28. uphawu concrete ezikhoyo - ku ezahlukene ukususela M800 ukuya M50 (kunye ukwandisa mninzi ukusuka ukwanda kwisalathiso wokwamanani). Kuba zokwakha ngamnye lisusiwe eziphathekayo ngaphezu kwibanga 400.

Noko ke, amandla ibango ixabiso uphawu ilabhoratri, ekubeni xa kusenziwa kuchaphazela inani lemiba ukungazinzi ezifana yokuphazamiseka ubuchwepheshe yokuvelisa, intlabathi umgangatho ukungafani kunye namanzi, kwaye ukutshintsha isicwangciso ngokubekwa iimeko. Konke oku kukhokelela ekuncipheni iimpawu amandla. Kwaye lo isiphoso okanye lomlingani yokwahluka umahluko ophambili phakathi kwe udidi eziphathekayo kwi brand yayo. Okubalulekileyo koko nje amandla kanye nge (5%) kutenxa encinane. Kulo mkhuba yeklasi eziphathekayo - inani ebalulekileyo abaliweyo isetyenziswa (nshita amanqaku) kuyilo izityalo elizayo. Kulinganiswa e MPA, kwaye kulawulwa GOST 26633-85. Xa iyonke kukho elinesithandathu kweeklasi amandla ukusukela kuma-3.5 ngo ku 60.

Ezi mpawu qualitative zilandelayo - ukumelana amanzi kunye nokumelana iqabaka - zihlelwa kuphela namanqaku.

Mark ikhonkrithi, ubonakalise iqabaka kwakhona ixabiso elebhu. It imela ubuninzi lwamanani isibonisi izixa zeemvavanyo apho isampuli phantsi ngumkhenkce-obuhle. Iqabaka amanqaku ezisibhozo ekufunwa ngayo ezahlukeneyo ukususela 50 F ukuya 500 F.

Enye ubunjalo uphawu - grade eziphathekayo ukuxhathisa kwamanzi. Kuba kophawu zingangenwa isicelo amabakala ezintandathu ukusukela kuma-12 W ukuya W2, leyo ixabiso ubuninzi uxinzelelo lwamanzi apho iisampulu reference abakwazi Kwathi amanzi (ngokuxhomekeke kwiimeko eziqhelekileyo testing).
