Ama-Aggregates ziyizingxenye ezibalulekile zekhonkrithi. Zisebenza njengezinto ezingasebenzi kukhonkrithi. I-aggregate encane neyimbi yizinhlobo ezimbili eziyinhloko ze-aggregate kukhonkrithi. Njengoba igama lisho, zihlukaniswa ngokuyisisekelo kuye ngobukhulu bezinhlayiya ze-aggregate.
Kuyini i-Aggregate?
Ama-aggregate ayizinto ezibalulekile zekhonkrithi ezinika umzimba kukhonkrithi futhi zinciphise ukushwabana. Ama-aggregate athatha u-70 kuya ku-80% womthamo wekhonkrithi uwonke. Ngakho-ke, singasho ukuthi umuntu kufanele azi kahle ngama-aggregate ngokujulile ukuze afunde kabanzi ngokhonkrithi.
Kuyini i-Fine Aggregate??
Uma i-aggregate ihlungwa ngesihlungo esingu-4.75 mm, i-aggregate idlula kuyo ibizwa ngokuthi i-aggregate encane. Isihlabathi semvelo sivame ukusetshenziswa njenge-aggregate encane, udaka nobumba nakho kube ngaphansi kwalesi sigaba.
Kuyini i-Coarse Aggregate??
Uma i-aggregate ihlungwa ngesihlungo esingu-4.75 mm, i-aggregate egciniwe ibizwa ngokuthi i-aggregate eqinile. Itshe eliyitshe, amatshe aqinile kanye namatshe amakhulu angaphansi kwalesi sigaba. I-aggregate yobukhulu obukhulu esetshenziswayo ingase incike ezimweni ezithile. Ngokuvamile, i-aggregate yobukhulu obungu-40 mm esetshenziselwa amandla ajwayelekile kanye nobukhulu obungu-20 mm isetshenziselwa ukhonkolo onamandla aphezulu.
Umehluko Phakathi Kokuhle Nokuhlanganisiwe Okukhulu
I-aggregate encane neyi-marrow inemehluko omkhulu. Imithombo yomehluko omkhulu phakathi kwezinyawo ezijulile nezingajulile yincazelo, ubukhulu bezinhlayiya, izinto zokwakha, imithombo, indawo engaphezulu, umsebenzi kukhonkolo, ukusetshenziswa, njll.
Kuleli thebula elilandelayo umehluko omkhulu phakathi kwe-Fine kanye ne-coarse aggregate unikezwe:
