Umxokelelwane uchazwa njengento ngaphandle kwamanzi, i-Agergates, isixhobo se-Hydraulic isixhobo esisetyenziswa njengesithambiso somxube we-cemeriting ukuguqula i-certch, i-Stopred Arch kwi-Batch ngaphambi okanye ngexesha lokuxuba . Njengoko kuphawuliwe kwiCandelo le-1, ukuhlengahlengiswa kwekhemikhali kudla ngokuchazwa ngakumbi njenge-nopololic (ayifuni i-calcium hydroxide ukuba iphendule) i-adming kwifom yolwelo, ukunqunyanyiswa okanye inyibilikisi okanye inyibilikisi.

Ukucutha amanzi okunciphisa amanzi Ukuphucula iPlanethi yeTript yeTript (ethe tyaba) kunye ne-Propeeding Procerties, ngelixa ulawula ukulawula kusetyenziswa kwikhonkrithi ebekwe kwaye kugqitywe ngaphandle kwamaqondo obushushu agqityiweyo. Zombini, xa zisetyenziswa ngokufanelekileyo, zinegalelo kwiindlela ezilungileyo zokuvumelana. Zombini ezi zinto ziqaqanjiweyo mazifezekise iimfuno ze-ASTM C 494 (jonga iTafile 1).

Ukunciphisa amanzi

Abanciphisi bamanzi benza oko: ukunciphisa isixa sokudibanisa amanzi afunekayo ukufumana isisu esinikiweyo. Oku kunokubangela ukuncitshiswa komgangatho wobungakanani bamanzi (W / C Rakua), okukhokelela kumandla anqabileyo kunye nekhonkrithi eqinileyo.

Ukunciphisa umlinganiselo wekhonkrithi we-W / C kwikhonkrithi kuchongwe njengeyona nto ibalulekileyo ekwenzeni ikhonkrithi enesidima, esemgangathweni. Kwelinye icala, ngamanye amaxesha umxholo wesamente unokuthotywa ngelixa ugcina umlinganiso we-W / C ukunciphisa iindleko okanye ubushushu be-hydrate yekhonkrithi yekhonkrithi.

Ukucutha amanzi okunciphisa amanzi kukwanciphisa ukwahlula kunye nokuphucula ukuhamba kwekhonkrithi. Ke ngoko, zihlala zisetyenziselwa izixhobo zekhonkrithi zekhonkrithi.

Ukucutha amanzi ngokunciphisa imixokelelwano ngokwesiqhelo ukuwela kumaqela amathathu: amathanga asezantsi-, ophakathi kunye noluhlu oluphezulu. La maqela asekwe kuluhlu lokunciphisa amanzi okuxhokonxa. Ipesenti yokuncitshiswa kwamanzi ihambelana nomxube wamanzi oqobo ofunekayo ukufumana i-slump enikiweyo (jonga kwiTheyibhile 2).

Ngelixa bonke abanqodlayo ngamanzi banokufana, nganye inesicelo esifanelekileyo esifanele sibe sesona silungileyo. Itheyibhile 3 ibonisa isishwankathelo seentlobo ezintathu zokunciphisa amanzi, imiqolo yazo yokuncitshiswa kwamanzi kunye nokusetyenziswa kwazo. Impembelelo yabo ekungeneni kwabo komoya iya kwahluka ngokuxhomekeke kwi chemistry.

Basebenza njani

Xa isamente iza kudibana namanzi, ukungafani neendleko zombane ezingafaniyo kumphezulu we-ceaments zitsalane, ezikhokelela kwindiza okanye kwiqela lamasuntswana. Isahlulo esihle samanzi singene kule nkqubo, ngaloo ndlela sikhokelela kumxube odibeneyo kwaye sinciphise i-slump.

Ukunciphisa amanzi ngokunciphisa izinto ezincomekayo ngokungaziphathi kakuhle kwizinto eziqinileyo ngamasuntswana aqinileyo kwaye ubangele yonke imiphezulu yokuthwala iindleko. Kuba amasuntswana anezityholo ezinjengenye, anciphise ukubhalwa kwamasuntswana e-celement kwaye avumele ukusasazeka okungcono. Zikwanciphisa i-viscofity ye-pascofity, ikhokelela kwisisu esikhulu.

Itheyibhile 4 ibonisa ezinye zezinto eziqhelekileyo ezisetyenziselwa uluhlu ngalunye lwamanzi. Amanye amacandelo akongezwa ngokuxhomekeke kwimveliso nomenzi. Ukucutha amanzi okunciphisa amanzi kuneziphumo zenqanaba lesibini okanye kudityaniswa nabahlali okanye abakhalikisi.
