Ukusebenza kwesisombululo sekhonkrithi kuxhomekeka kwiimpawu zokusebenza kwale ndawo. Eyona mfuno iphambili kumxube wekhonkrithi ngamandla ecinezelayo. Ilinganiswa ngeekhilogrem kwisentimitha nganye (kg / cm2) okanye kwiMegapasters (MPA). Ngokwezi zikhombisi, umbandela wabelwe uphawu (m) nodidi (b).
UMark -Ukuchazwa okungaphezulu kwe-ofsolete kuneklasi. Kwisimetho-medimes-ikhonkrithi, uluhlu olubanzi lweempawu, ukusukela kwi-M25 kwaye iphele nge-M1000. Kodwa kulwakhiwo lwemfuno rhoqo alikho ngaphezulu kweshumi. Isalathiso sisetyenziswa kwimiyalelo ye-oda.
Idijithi yophawu ingaphezulu, ikhonkrithi yomelele. Umzekelo, i-M250 inamandla angama-262 kg / cm2, kunye ne-M350 - 327 kg / cm2.
Iklasi-ilinganiswe kwi-megapascals (MPA). Bangama-21 ukusuka kwi-B3.5 ukuya b80. Kodwa, njengabahlobo, malunga neshumi elinambini lithandwa. Lo mboniso usetyenziswa kumsebenzi weprojekthi.
Uphawu ngalunye lungalinganiswa kwiklasi ethile kunye ne-vice vice verda.
Ukuphelela umyinge kukho itafile:
Uvavanyo lokucinezelwa lwenzeka kwilabhoratri enezixhobo ezizodwa - umatshini woshicilelo. Ukufumanisa isampulu yekhonkrithi ye-frozen kwifom ye-cube encinci okanye i-cylinder ithatha. Iisampulu zezinto ezibonakalayo ziqokelelwa ngosuku lwesi-7 ukuya emva kokugalela, kwaye kwiintsuku ezingama-28 emva kokuqonda ngokupheleleyo. Babekwa kwimithombo yeendaba kwaye ngokuthe ngcembe bayonyusa uxinzelelo kude kutshabalale ngokupheleleyo. Ixabiso lesiphumo esikhundleni kwaye liya kuba namandla okwenza uxinzelelo.
Kukho iintlobo ezingathanga ngqo zophando:
- ukuvuselelwa kwe-elastic;
- i-ultrasound;
- indlela yokwahlula;
- ukubetha.
Kunye nokudityaniswa kweendlela ezahlukeneyo.
Kwindlela yokuqala, amandla okuqala kwakhona kwibhola yensimbi evela kumphezulu wekhonkrithi ilinganiswa ngokusebenzisa izixhobo zokulinganisa: isando se-Schmidt okanye i-sclermer ye-Schmidt okanye i-sclermer's Hammer okanye i-sclerometer.

Ukomelela kuvavanywa ngokweedatha eziya kubonisa isimo sezulu.
Kwindlela yesibini, iimitha ze-ultrasound ziyasetyenziswa. Inokuba yisandi esiyi-superficialial. Umlinganiselo wokuphela wokuphela uyasetyenziswa xa kukho ithuba lokuncamathisela abaguquli ngokuchaseneyo: umzekelo, kwiikholamu. Ngale ndlela, isantya sokudlulisela amaza ngezixhobo zimiselwe. Isandi sesandi somphezulu sirekhodwe lixesha lokucamngca ngamaza kulo lonke ulwakhiwo lwekhonkrithi. Imitha isetyenziswa kumphezulu.
Ngexesha lovavanyo, indlela yokwahlula-hlula ilinganiswa ngemizamo eqhotyoshelwe ukwahlulahlula iqhekeza lemveliso yekhonkrithi. Ukwenza oku, glue idiski yentsimbi okanye ufake i-anchor kunye ne-curut iqhagamshelwe kwisixhobo sokulinganisa. Sebenzisa imizamo ephezulu yokutshatyalaliswa kwemali.
Indlela yempembelelo ibandakanya ukuthelekisa iiprinta ezishiywe emva kogwayimbo lwe-fidzel hammer okanye isando ye-kashkarova. Ngale ndlela, thatha isampulu kunye namandla awaziwayo kwaye uphume kwindawo yokuphumla kuyo usebenzisa isixhobo. Ke kukho amaqula afanayo kumphezulu wento. Ekupheleni faka ixabiso eliphakathi lobunzulu okanye ububanzi beeprinta ngomgangatho. Ngokusekwe kule datha, amandla amiselweyo.
Ukukhetha kwendlela ethile kuxhomekeke kuhlobo lweekhonkrithi zekhonkrithi kunye namathuba okwenza ubungakanani obuthile. Eli nqaku lichaza iindlela ezisisiseko kuphela, kodwa kusekho iindidi ezahlukeneyo onokuzifumana kwimigangatho ye-Intertate: Gost 10180-90, phuma 17624-2012 kwaye u-22690.
