Libuka tsa mantsoe, konkreite le seretse ho ka ba ferekanya tse qalang, empa phapang ea mantlha ke samente le lehlabathe, 'me konkreite e entsoe ka samente, lehlabathe le lehlohlojane. Ntle le metsoako ea bona e fapaneng, ts'ebeliso ea bona e fapane haholo. Le bahoebi ba sebetsang le lisebelisoa tsena ba ka ferekanya mantsoe ana ka puo ea Colloquia, joalo ka samelise hangata ho bolela konkreite.
Samente
Samente ke tlamo pakeng tsa konkreite le seretse. Hangata e etsoa ka lejoe la lepheo, letsopa, likhetla le lehlabathe la silica. Lisebelisoa li sithabetse ebe li tsoakoa ka metsoako e meng, ho kenyeletsa le ore ea Iron, ebe o futhumetse ho Demreses. Lingoliloeng tsena, tse bitsoang Clinker, li ka phofo e ntle.

Kajeno, samente ea portland e ntse e le samente e sebelisoang haholo. Ke samtealic ""
Konkreite
Lefatšeng ka bophara, konkreite e sebelisoa e le motheo o matla le lits'ebeletso tse ngata tsa hoo e ka bang mofuta oa moaho. It is unique in that it starts out as a simple, dry mixture, then becomes a liquid, elastic material that can form any mold or shape, and finally becomes a rock-like hard material that we call concrete.
Konkreite e na le samente, lehlabathe, lehlohlojane kapa tse ling tse ntle kapa tse ntle. Ho eketsoa ha metsi ho sebelisa samente, e leng ntho e ikarabellang bakeng sa ho tlama motsoako hammoho ho theha ntho e tiileng.
U ka reka motsoako o entsoeng ka konkreiti e entsoeng ka mekotla e kopanyang samente, lehlabathe, le lehloeo hammoho, le sohle se lokelang ho se etsa ke ho eketsa metsi.
Tsena li na le thuso bakeng sa merero e menyenyane, joalo ka lipehelo tsa terata kapa liphio tse ling. Bakeng sa merero e meholo, o ka reka mekotla ea samente ebe o e kopanya le lehlabathe le inesetiki e kholo, kapa u romelle konkreite.
Seretse
Seretse se entsoe ka samente le lehlabathe. Ha metsi a kopantsoe le sehlahisoa sena, samente e sebetsa. Ha konkreiti e ka sebelisoa ke le mong, seretse se sebelisetsoa ho thibela lejoe, lejoe, kapa likarolo tse ling tse thata tsa naha hammoho. Ho kopanya le ho kopanya, ka hona, ka nepo, e bua ka tšebeliso ea samente ho kopanya seretse kapa konkreiti.
Kahong ea panenti ea litene, ka linako tse ling e sebelisoa pakeng tsa litene, leha e le ka tsela ena ha e sebelisoe kamehla. Ka mohlala, libakeng tse ka leboea, tse seretseng habonolo mariha, ka hona litene li ka sithabela haholo, kapa lehlabathe le ekelitsoe mahareng, kapa lehlabathe le ekelitsoeng pakeng tsa tsona.
