Injongo ngokubanzi portland isamente

Injongo ngokubanzi Isamente yasePortland luhlobo lwesamente yehydraulic esetyenziswa ngokuqhelekileyo ekwakheni. Yenziwa ngokusila i<em>clinker, luhlobo lwelitye likalika elithe lafudunyezwa kumaqondo obushushu aphezulu kakhulu kwaye lixutywe negypsum. Lo mxube uyagutywa ube ngumgubo ocolekileyo, osetyenziselwa ukwenza ikhonkrithi, udaka nezinye izinto zokwakha.

Enye yeenzuzo eziphambili zenjongo jikelele yesamente yasePortland kukuguquguquka kwayo. Ingasetyenziselwa uluhlu olubanzi lwezicelo, ukusuka ekwakhiweni kwezakhiwo ezinkulu ukuya ekudaleni iiprojekthi ezincinci zendlu. Ikwangabizi kakhulu, iyenza ibe lukhetho oludumileyo kuzo zombini iikontraka ezichwepheshile kunye nozenzele ngokwakho.

Enye inzuzo yenjongo ngokubanzi iPortland isamente ngamandla ayo. Xa ixutywe namanzi, yenza intlama eqina ekuhambeni kwexesha, ibe yinto ehlala ixesha elide, eqinileyo. Oku kuyenza ilungele ukusetyenziswa kwizicelo zoxinzelelo oluphezulu, njengeziseko zokwakha, iibhulorho, kunye nezinye izakhiwo ezifuna ukumelana nemithwalo enzima.

Ukongeza kumandla ayo, injongo eqhelekileyo yesamente yasePortland nayo ixhathisa kakhulu kwimozulu kunye nomonakalo weekhemikhali. Iyakwazi ukumelana neemeko ezimandundu zemekobume, kuquka imvula, umoya, namaqondo obushushu agqithisileyo, ngaphandle kokuphulukana nengqibelelo yayo yesakhiwo. Oku kuyenza ibe lukhetho oludumileyo kwiiprojekthi zangaphandle, ezinje ngeepatio, iindledlana zokuhamba, kunye neendonga zokugcina.

Injongo ngokubanzi Isamente yasePortland inokwenziwa ngokwezifiso ukuhlangabezana neemfuno ezithile zeprojekthi. Umzekelo, inokuxutywa kunye nezongezelelo ezahlukeneyo, ezifana nothuthu lwempukane okanye umsi wesilica, ukuphucula amandla ayo, ukuqina, okanye ukusebenza. Oku kuvumela iikontraka ukuba zilungelelanise isamente ukuhlangabezana neemfuno ezizodwa zeeprojekthi zabo.

Nangona kunjalo, kukho imida kwinjongo ngokubanzi yesamente yasePortland. Enye yeengxaki eziphambili yimpembelelo yayo yokusingqongileyo. Ukuveliswa kwesamente ngumthombo omkhulu wokukhutshwa kwekhabhoni, kwaye ukumbiwa kunye nokuthuthwa kwezinto eziluhlaza kunokuba nefuthe elibalulekileyo kwindalo. Ngenxa yoko, kukho intshukumo ekhulayo ekusetyenzisweni kwezinto zokwakha ezizinzileyo, ezifana nekhonkrithi ehlaziyiweyo, ukunciphisa impembelelo yokusingqongileyo kulwakhiwo.

Omnye umceli mngeni onenjongo ngokubanzi yesamente yasePortland ngamandla ayo okuqhekeka kunye nokuncipha. Xa isamente yomile, iba yinkqubo ebizwa ngokuba yihydration, nto leyo enokubangela ukuba inciphe kancinane. Ngokuhamba kwexesha, oku kucutheka kunokubangela ukuba isamente iqhekeke okanye ibe brittle, nto leyo enokuphazamisana nengqibelelo yayo yesakhiwo. Ukuthintela oku, iikontraki zingadinga ukusebenzisa izongezo ezikhethekileyo okanye izinto zokuqinisa, ezifana neentsimbi zentsimbi, ukuqinisekisa ukuba i-samente ihlala yomelele kwaye izinzile.

Ukuqukumbela, injongo jikelele yesamente yasePortland sisixhobo sokwakha esisebenza ngeendlela ezininzi, esihlala ixesha elide, esinexabiso eliphantsi esisetyenziswa ngokubanzi kulwakhiwo. Nangona inemida ethile, kubandakanywa impembelelo yayo yokusingqongileyo kunye nokukwazi ukuqhekeka kunye nokunciphisa, ihlala ithandwa kakhulu kwiiprojekthi zokwakha ezininzi. Njengoko ishishini lokwakha liqhubeka nokukhula kwaye lizinza ngakumbi, kunokwenzeka ukuba izinto ezintsha kunye nobuchwepheshe buya kuvela ukuze kuphuculwe ngakumbi ukusebenza kunye nozinzo lwenjongo jikelele yesamente yasePortland.
