Microcement

I-microcement yisimenti ekhethekile eluncane kakhulu, esunguliwe ngobuchwepheshe bokuthi iphakamiselwe ukunemba okukodwa kanye nokuhlela kahle (grouting) kanye nokuhlela okuncane (micro-scale injection) ezinhlakanipha zokuphakamiselwa umhlaba kanye nobuchwepheshe be-geotechnical engineering. I-microcement akhiwe ngezinhlaka zesimenti ye-Portland ezincane kakhulu—amtaku olinganiselwa we-3–15 micrometers kubudamela—okuncane kakhulu kunjesimenti ye-Portland ejwayelekile (amtaku olinganiselwa we-10–100 micrometers)—futhi ngokuvamile ihlanganiswa no-additives afanayo ne-plasticizer, ama-agent okunciphisa amanzi, kanye namanye i-silica fume noma ama-mineral filler ukuthola i-rheology ekuthintwe nokuqina okukhusele. Umbuza oncane kakhulu wezinhlaka uvumela ukungeneza ezigwegweni ezincinane, amaqhele amancane, kanye namasoil matrices asebulawa lula lapho i-simenti ejwayelekile ayikwazi ukufinyelela, okwenza i-microcement ibe yinto eyodwa kule emangalisayo ekumele isetshenziswe ekusiqiniseni umhlaba, ukunga umhlaba, kanye nokuthuthukisa isakhiwo zezinhlakanipha zokuphakamiselwa umhlaba.
