Cha ea samente: hore na ba tsamaea

Ka ho nahana ka ntho e joalo ka cha samente, o lokela ho nahana ka melao puo ea khale, har'a oona ke GOST30515-97 eo arola cements tsohle e khethehileng le ea lehae. metsoako Cementitious ka 'na na le makalana fapaneng (ferrite, k'halsiamo aluminate kapa Portland samente clinker) le na le a tlatsana le tse fapa-fapaneng matsoai.

Hape habohlokoa ho hlokomela ke hore Brands fapaneng na maemo e fapaneng ya samente compressive matla, a fapaneng sekhahla phekole (le ka tsela e tloaelehileng-bystrotverdeyushchie), linako tse sa tšoaneng ho sehela - ho na le ke motsoako hore qala ho thatafatsa ka mor'a metsotso e ka tlase ho 45 'me ho na le medlennoskhvatyvayuschiesya (tse fetang 2 lihora tse).

E mong le e cha ea samente ba lokela ho finyella palo ya ditekanyetso, ho akarelletsa le: ho itseng tse bonahalang sebopeho, nako thickening, matla compressive, samonapryazheniyu, samente segokanyipalo teko, e katoloso ya guttate, le dikahare tsa lik'hemik'hale hlokahalang (Ion chloride, oxide e sebabole, e oxide e ea MG), boemo ba ho arohana metsi , mocheso le litšobotsi tse ling.

Ithute ka ho hlophisoa ha samente motsoako ka ba ka lebitso la eona. Detailed decoding litšobotsi tse samente e ileng ea fuoa baeti ka holimo hammoho le ka GOST10178-85. Haeba lebitso la qala ho PC e - sena ke cha ea samente e thehiloeng Portland samente clinker, 'me haeba SPC - ka nako eo re slag le dikahare tse phahameng tsa slag boima (tse fetang 20%).

Mora mabitso feletseng kapa khutsufalitsoe ke linomoro tse makholo, e leng bolela matla compressive. Bakeng sa Portland bath nka 600, 550, 500, 400, bakeng sa slag e - linomoro ho tloha 500 ho 300. Hape, palo palo e kahodimodimo ho sebelisoe A0 (ha ho na additives) ho D20 boletsweng ka sehlooho (additives - 20%). Ka 'na ba le sesupo sa solidification potlako (D), samente hydrophobization le plastification tsa motsoako (PL, GF), tlhahiso ea samente clinker le ea ho hlophisoa boetse maemong (H) le kgokahanyo ho Standard ngollana.

Ka mohlala, cha samente PTS550-D5-B-PL ke Portland samente le matla compressive ea 550, le 5% additives bystrozatverdevayuschim le polasetiki.

Ho haha mohaho oo e le ea bohlokoa haholo hore lefela potoloho mesebetsi ba ileng ba tsoa ka tsela e atlehileng. hloko ka ho khetheha lokela ho fuoa ho motheong, eo hangata e entsoe ka konkreite.
