Izingxenye eziyinhloko zekhonkrithi zifaka phakathi usimende (kufaka phakathi izinto ezifaka usimende njengempuphu yamaminerali, umlotha wempukane, njll.), ama-aggregates (isihlabathi, itshe, i-ceramsite, njll.), amanzi, kanye nezingxube.
Igama elithi ukhonkolo livame ukubhekisela kukhonkolo wesamente njengento ehlanganisa ukhonkolo, isihlabathi kanye netshe njengezinto ezihlanganisiwe; kuxutshwa namanzi (okungase kube nezingxube nezingxube) ngesilinganiso esithile, kanti ukhonkolo wesamente otholakala ngokuxubha ubizwa nangokuthi ukhonkolo ojwayelekile. Ukhonkolo, osetshenziswa kabanzi kwezobunjiniyela bezezakhiwo.
Ikhonkrithi inezici zezinto zokusetshenziswa eziningi, amanani aphansi, kanye nenqubo yokukhiqiza elula, ngakho ukusetshenziswa kwayo kuyanda. Ngesikhathi esifanayo, ikhonkrithi inezici zamandla aphezulu okucindezela, ukuqina okuhle, kanye nobubanzi bamazinga anamandla.
Lezi zici zenza isetshenziswe kabanzi, hhayi nje kuphela kwezobunjiniyela bezokwakha kodwa nasekwakheni imikhumbi, embonini yemishini, ekuthuthukisweni kolwandle, ubunjiniyela be-geothermal, njll. Ukhonkolo nawo uyinto ebalulekile.
Kukhonkolo, isihlabathi namatshe kudlala indima yamathambo, okubizwa ngokuthi i-aggregate; usimende namanzi kwakha i-samente slurry, kanti i-samente slurry igoqa ubuso be-aggregate futhi igcwalise izikhala zayo. Ngaphambi kokuqina, i-grout idlala indima yokugcoba, inika ingxube amandla athile okusebenza futhi ilula ukwakhiwa. Ngemva kokuba i-samente paste iqine, i-aggregate iqiniswa ibe yinto eqinile.
Ukukhetha izinga lesimende kufanele kuhambisane nezinga lamandla okuklama kwekhonkrithi. Ngokuyisisekelo, kulungiswa ikhonkrithi enamandla aphezulu, bese kusetshenziswa i-samente yezinga eliphezulu; uma kulungiswa ikhonkrithi enamandla aphansi, kukhethwa i-samente yezinga eliphansi.
Uma kudingeka ukusebenzisa usimende wezinga eliphezulu ukulungisa ukhonkolo wezinga eliphansi, inani lesimende lizoba lincane kakhulu, okuzothinta ukusebenza kahle kanye nokuqina, ngakho-ke kufanele kwengezwe inani elithile lezinto ezixubile. Uma kudingeka ukusebenzisa usimende wezinga eliphansi ukulungisa ukhonkolo wezinga eliphezulu, inani lesimende lizoba liningi kakhulu, okungeyona eyongayo futhi okuzothinta ezinye izakhiwo zobuchwepheshe zekhonkolo.
