Izinto eziphambili zekhonkrithi ziquka isamente (kuquka izinto ezisebenzisa isamente ezifana nomgubo weeminerali, uthuthu lwempukane, njl. njl.), izinto ezidityanisiweyo (isanti, ilitye, i-ceramsite, njl.njl.), amanzi, kunye nezinto ezixutyiweyo.
Igama elithi concrete lidla ngokubhekisa kwiconcrete yesamente njengezinto ezisetyenziswa kwisamente, isanti kunye namatye njengezinto ezidityanisiweyo; ixutywa namanzi (anokuthi aqulathe izinto ezidityanisiweyo kunye nezinto ezidityanisiweyo) ngokwemilinganiselo ethile, kwaye iconcrete yesamente efunyenwe ngokuxutywa ikwabizwa ngokuba yiconcrete eqhelekileyo. Iconcrete, esetyenziswa kakhulu kubunjineli bezakhiwo.
Ikhonkrithi ineempawu zokuba zininzi izinto ezikrwada, amaxabiso aphantsi, kunye nenkqubo elula yokuvelisa, ngoko ke ukusetyenziswa kwayo kuyanda. Kwangaxeshanye, ikhonkrithi ikwanazo iimpawu zokuba namandla aphezulu okuxinzelela, ukuqina okuhle, kunye noluhlu olubanzi lwamanqanaba okuqina.
Ezi mpawu ziyenza isetyenziswe kakhulu, kungekuphela nje kwiinjineli ezahlukeneyo kodwa nakwizakhiwo zeenqanawa, kushishino lwemishini, kuphuhliso lolwandle, kubunjineli be-geothermal, njl. Ikhonkrithi nayo iyinto ebalulekileyo.
Kwikhonkrithi, isanti kunye nelitye zidlala indima yamathambo, ebizwa ngokuba yi-aggregate; isamente kunye namanzi zenza i-samente slurry, kwaye i-samente slurry igubungela umphezulu we-aggregate ize izalise izithuba zayo. Ngaphambi kokuba iqine, i-grout idlala indima yokuthambisa, inika umxube amandla athile okusebenza kunye nokwenza kube lula ukwakhiwa. Emva kokuba i-samente paste iqine, i-aggregate iqiniswa ibe yinto eqinileyo.
Ukukhethwa komgangatho wesamente kufuneka kuhambelane nomgangatho woyilo lwesamente. Ngokwesiseko, kulungiswa isamente enamandla aphezulu, kwaye kusetyenziswa isamente ephezulu; xa kulungiswa isamente enamandla aphantsi, kukhethwa isamente ephantsi.
Ukuba kuyimfuneko ukusebenzisa isamente yodidi oluphezulu ukulungiselela ikhonkrithi yodidi oluphantsi, ubungakanani besamente buya kuba mncinci kakhulu, nto leyo eya kuchaphazela ukusebenza kakuhle kunye nobunzima, ngoko ke kufuneka kongezwe ubungakanani obuthile bezinto ezixutyiweyo. Ukuba kuyimfuneko ukusebenzisa isamente yodidi oluphantsi ukulungiselela ikhonkrithi yodidi oluphezulu, ubungakanani besamente buya kuba buninzi kakhulu, nto leyo engabizi kakhulu kwaye iya kuchaphazela ezinye iimpawu zobugcisa zekhonkrithi.
