Kuyini udaka lwamatshe?

Udaka lwamatshewuhlobo lwezinto ezisekelwe kusimende ezisetshenziswa ekwakhiweni kwezitini, amatshe, nezinye izakhiwo zamatshe. Kuyingxube usimende, isihlabathi, amanzi, futhi ngezinye izikhathi izithasiselo ezengeziwe ukuthuthukisa izakhiwo zayo.

Udaka lwamatshe lusetshenziselwa ukuhlanganisa amayunithi amatshe ndawonye, ​​​​okuhlinzeka ngobuqotho besakhiwo ezindongeni, amakholomu, amakhothamo, nezinye izakhi zamatshe. Ukwakheka okukhethekile kodaka kungahlukahluka kuye ngokuthi kuhloswe ukusetshenziswa kanjani, isimo sezulu, kanye nohlobo lokwakha olusetshenziswayo.

Udaka lwamatshe lungenziwa kusetshenziswa izinhlobo ezihlukene zikasimende, njengosimende wasePortland noma usimende owenziwe nge-lime, futhi isihlabathi esisetshenziswa kule ngxube singahlukahluka ngobukhulu nokuthungwa. Isilinganiso sikasimende nesihlabathi singahlukahluka, kuye ngamandla afunekayo nokusebenza kodaka.

Izithasiselo zingafakwa engxubeni yodaka ukuze kuthuthukiswe izakhiwo zayo, njengokuxosha amanzi, ukusebenza kahle, namandla okubopha. Isibonelo, ama-plasticizers noma izinciphisi zamanzi zingangezwa ukuthuthukisa ukusebenza, kuyilapho izinto ze-pozzolanic ezifana nomlotha wempukane noma i-silica fume zingangezwa ukwandisa amandla nokuqina.

Sekukonke, udaka lwamatshe luyingxenye ebalulekile ekwakhiweni kwezakhiwo zamatshe, enikeza amandla adingekayo okubopha ukuze kuqinisekiswe ukuzinza nokuqina kwesakhiwo sonke.
