Aggregates zvinhu zvakakosha zvekongiri. Vanoita sechinhu chine inert mukongiri. Fine and coarse aggregate ndiwo marudzi maviri makuru eaggregate yekongiri. Sezvinoratidzwa nezita racho, iwo akaiswa mumapoka zvichienderana nehukuru hwezvimedu zvakaunganidzwa.
Chii chinonzi Aggregate?
Aggregates ndizvo zvakakosha zvinoumba kongiri izvo zvinopa muviri kune kongiri uye zvakare kuderedza shrinkage. Aggregates anotora 70 kusvika 80% yehuwandu hwehuwandu hwekongiri. Saka, isu tinogona kutaura kuti munhu anofanirwa kuziva chokwadi nezve aggregates zvakadzama kuti adzidze zvakawanda nezve kongiri.
Chii chinonzi Fine Aggregate??
Kana iyo aggregate ichisefa kuburikidza nesefa ye 4.75 mm, muunganidzwa wakapfuura nemauri unonzi sefine aggregate. Jecha remusikirwo rinowanzo shandiswa seyakanaka aggregate, silt nevhu zvakauyawo pasi pechikamu ichi.
Chii chinonzi Coarse Aggregate??
Kana aggregate ichisefa kuburikidza nesefa ye4.75 mm, muunganidzwa unochengetwa unonzi coarse aggregate. Gravel, cobble uye matombo anouya pasi pechikamu ichi. Iyo yakanyanya saizi aggregate inoshandiswa inogona kutsamira pane mamwe mamiriro. Kazhinji, 40 mm saizi aggregate inoshandiswa kune zvakajairika masimba uye 20mm saizi inoshandiswa kune yakakwirira simba kongiri.
Musiyano pakati peFine uye Coarse Aggregate
Yakakwana uye yakaoma aggregate ine mimwe misiyano mikuru. Masosi emisiyano mikuru pakati peyakadzika uye isina kudzika tsoka tsananguro, saizi yezvimedu, zvinhu, masosi, nzvimbo yepamusoro, basa mukongiri, kushandiswa, nezvimwe.
Mutafura inotevera misiyano mikuru pakati peFine uye coarse aggregate inopihwa:
