Zvikamu zvakaunganidzwa zvinhu zvakakosha zvekongiri. Zvinoshanda sechinhu chisina kusimba mukongiri. Aggregate yakatsetseka neyakakora mhando mbiri huru dzeaggregate yekongiri. Sezvinoratidzwa nezita racho, zvinorongwa zvichienderana nehukuru hweaggregate particles.
Chii chinonzi Aggregate?
MaAggregates ndiwo akakosha mukongiri anopa muviri kune kongiri uye anoderedzawo kupwanyika. MaAggregates anogara 70 kusvika 80% yehuwandu hwese hwekongiri. Saka, tinogona kutaura kuti munhu anofanira kuziva zvakadzama nezvemaAggregates kuti adzidze zvakawanda nezvekongiri.
Chii chinonzi Fine Aggregate??
Kana aggregate ikaseferwa nemusefa we 4.75 mm, aggregate inopfuura nepakati payo inonzi fine aggregate. Jecha rechisikigo rinowanzo shandiswa se fine aggregate, silt nevhu zvakapindawo muchikamu ichi.
Chii chinonzi Coarse Aggregate??
Kana aggregate ikaseferwa nemusefa we4.75 mm, aggregate inosara inonzi coarse aggregate. Matombo, madombo ematombo nematombo zvinouya muchikamu ichi. Aggregate yehukuru hwepamusoro inoshandiswa inogona kutsamira pane zvimwe zvinhu. Kazhinji, aggregate yehukuru hwe40 mm inoshandiswa pakusimba kwakajairika uye saizi ye20mm inoshandiswa pakugadzira kongiri yakasimba kwazvo.
Musiyano Pakati Pezvakawanda Zvakanaka Nezvakawanda
Zvinhu zvakakora uye zvakakora zvine musiyano mukuru. Zvinhu zvinonyanya kusiyana pakati pezvikamu zvakadzika nezvisina kudzika zvinosanganisira tsananguro, saizi yezvimedu, zvinhu, manyuko, nzvimbo yepamusoro, mashandiro ari mukongiri, mashandisirwo, nezvimwewo.
Mutafura inotevera mutsauko mukuru uripo pakati peFine necoarse aggregate unopiwa:
