Ipavumente yesamente yipavumente eqhelekileyo ngoku.Kuphela ngokuqinisekisa ngokubanzi amandla, ukuthamba kunye nokunganyangeki kokunxiba, okunokuthi kuphunyezwe ukugcwala okukumgangatho ophezulu.Eli phepha lenza uhlalutyo olubanzi kulwakhiwo lwendlela yesamente yekhonkrithi ukuze kuphuculwe ukusebenza kwayo kunye nokuhlangabezana neemfuno zezithuthi ezikumgangatho ophezulu.

Ubunjineli bePavement yeyona ndawo ibalulekileyo yobunjineli bokwakhiwa kweendlela.Ayisebenzisi kuphela izinto ezininzi, kodwa ineenkqubo ezinzima.Ukuba ayiphathwa ngokufanelekileyo, kuya kwenzeka iingxaki, ezichaphazela ukhuseleko lwezithuthi.Esona siphumo sithe ngqo sonyango olungafanelekanga lwendlela yendlela kukuba izakhiwo ezinovakalelo ziya kuveliswa ngenxa yokutshintsha kobushushu obungaphandle, okukhokelela kwiingxaki ezahlukeneyo zomgangatho wepavumente.Imimandla eyahlukeneyo kufuneka ikhethe ngokubanzi ifom yendlela yendlela ngokwendawo yayo, kwaye iphucule ngokubanzi amandla okuqonda okukhethwa kwezinto eziluhlaza, ukwakheka komgangatho, inqanaba lovavanyo lovavanyo, ulawulo lwenkqubo yokwakha, umgangatho wenkqubo, inqanaba letekhnoloji yezixhobo, indawo yokwakha, njl. ., ukuze kwakhiwe isiseko sokwakhiwa koohola beendlela ezikumgangatho ophezulu.Okwangoku, i-pavement eqhelekileyo yi-samente ye-concrete pavement, enozinzo oluphezulu ngenxa yokunyanzeliswa kwayo, ukugoba kunye nokuxhatshazwa kwe-abrasion.Kwangaxeshanye, olu hlobo lwepavement lukwanazo iingenelo ezininzi, ezinjengobomi benkonzo ende, iindleko zokuyilungisa ezingaphantsi kwemihla ngemihla, kwaye kulungele ukuqhuba ebusuku.Ukuze kuqinisekiswe ukuba ipavumente yesamente yekhonkrithi inokudlala indima yayo efanelekileyo, ifuna uyilo olunenkathalo kunye nolwakhiwo olungqongqo, ukuze kuqinisekiswe umgangatho kunye nokudlala kwiinzuzo zepavumente yesamente.

Ukukhethwa kwamanzi ongezelelweyo:

Ukwakhiwa kwesamente kufuna i-admixtures eninzi, enokuphucula amandla kunye nobunzima besamente.I-admixtures ikakhulu ibandakanya i-ejenti yokunciphisa amanzi, i-agent e-fluidizing kunye nezinye izinto.Ngokuxuba kunye nesamente, ukuqina kwekhonkrithi kunokuphuculwa ngokubanzi.Amanzi acocekileyo angenabumdaka aya kukhethwa ukuba asetyenziswe.Amanzi anokungcola akakwazi ukusetyenziswa, okuya kuchaphazela ukuqina kwesamente.

Impembelelo yemali eyongezelelweyo kwi-concrete slump:

I-additive yinto ebalulekileyo.Isixa saso sinempembelelo enkulu kwi-concrete slump kwaye yenye yezinto eziphambili.I-additive yi-catalyst yokukhuthaza iimpawu ezibonakalayo kunye neekhemikhali zekhonkrithi.Ubuninzi okanye obuncinci abuyi kuvelisa iziphumo ezilungileyo.
