Izvo zvakakosha zvekongiri zvinosanganisira simende (kusanganisira simenti zvinhu zvakaita semineral poda,kubhururuka madota, nezvimwewo), zvakaunganidzwa (jecha, dombo, ceramsite, nezvimwewo), mvura, uye musanganiswa.
Izwi rokuti kongiri rinowanzoreva kongiri yesamende sezvinhu zvine simende, jecha nematombo zvakabatana; inosanganiswa nemvura (iyo inogona kunge iine admixtures uye admixtures) mune chimwe chikamu, uye kongiri yesamende inowanikwa nekukuchidzira inonziwo kongiri yakajairika. Concrete, iyo inoshandiswa zvakanyanya muinjiniya yehurumende.
Concrete ine hunhu hwezvakawanda zvekushandisa, mitengo yakaderera, uye nyore kugadzira maitiro, saka kushandiswa kwayo kuri kuwedzera. Panguva imwecheteyo, kongiri zvakare ine hunhu hwesimba rakanyanya kudzvanya, kusimba kwakanaka, uye kuwanda kwemagiredhi esimba.
Aya maitiro anoita kuti ishandiswe zvakanyanya, kwete chete muinjiniya dzakasiyana siyana asiwo mukuvaka ngarava, indasitiri yemichina, kuvandudzwa kwegungwa, geothermal engineering, etc. Concrete zvakare chinhu chakakosha.
Mukongiri, jecha nematombo zvinotamba basa re skeleton, iyo inonzi aggregate; simiti nemvura inoumba simenti slurry, uye simenti slurry inoputira pamusoro peaggregate uye inozadza voids yayo. Isati yaoma, grout inoita basa rekuzora, ichipa musanganiswa kumwe kushanda uye kufambisa kuvaka. Mushure mekunge simende paste yaoma, iyo aggregate inosimbiswa kuita yakasimba yakazara.
Kusarudzwa kwegiredhi resimende kunofanirwa kuwirirana negiredhi rekugadzira simba rekrete. Muchidimbu, kongiri yegiredhi yakakwirira-yakasimba inogadzirwa, uye simende yepamusoro-giredhi inoshandiswa; apo kongiri yegiredhi yakaderera inogadzirwa, samende yakaderera inosarudzwa.
Kana zvakakosha kushandisa simenti yepamusoro kugadzirira kongiri yegiredhi yakaderera, huwandu hwesimende huchave hudiki, izvo zvinokanganisa kushanda uye kusimba, saka huwandu hwezvinhu zvakasanganiswa hunofanira kuwedzerwa. Kana zvakakosha kushandisa samende yepasi-giredhi kugadzirira kongiri yakasimba-yakasimba giredhi, huwandu hwesimende huchave hwakawandisa, husiri hwehupfumi uye huchakanganisa humwe hunyanzvi hwekongiri.
