Lub ntsiab technical zog ntawm pob zeb

Cov khoom ntawm pob zeb muaj xws li kev ua haujlwm ntawm pob zeb sib xyaw, lub zog, deformation thiab durability ntawm pob zeb.
Workability, tseem hu ua workability, yog hais txog cov pob zeb sib tov nyob rau hauv tej yam kev mob ntawm kev tsim kho, los pab txhawb kev khiav hauj lwm ntawm ntau yam kev tsim kho txheej txheem, thiaj li yuav xyuas kom meej cov kev ua tau zoo ntawm uniform ntom pob zeb. Kev ua haujlwm tau zoo yog qhov ntsuas kev qhia dav dav, suav nrog fluidity (ib puag ncig), cohesiveness thiab dej tuav peb yam tseem ceeb.
Lub zog yog cov cuab yeej tseem ceeb ntawm cov pob zeb tom qab hardening, uas qhia txog qhov muaj peev xwm ntawm cov pob zeb los tiv thaiv kev thauj khoom. Lub zog pob zeb muaj xws li compressive zog, tensile zog, shear zog, dabtsi yog khoov zog, folding zog thiab tuav lub zog. Ntawm lawv, lub zog compressive yog qhov loj tshaj plaws thiab lub zog tensile yog qhov tsawg tshaj plaws.
Lub deformation ntawm pob zeb muaj xws li deformation tsis muaj load thiab deformation nyob rau hauv load. Non-load deformation muaj xws li tshuaj shrinkage, qhuav thiab ntub deformation thiab kub deformation. Tus nqi ntawm cov cement ntau dhau, uas yog ib qho yooj yim los tsim cov tshuaj shrinkage nyob rau hauv cov pob zeb sab hauv thiab ua rau micro-cracks.
Kev ua vaj tse pob zeb yog hais txog lub peev xwm ntawm pob zeb los tiv thaiv ntau yam kev puas tsuaj thiab tuav nws lub zog thiab zoo li kev ncaj ncees rau lub sijhawm ntev raws li kev siv tiag tiag. Nws suav nrog kev tiv thaiv khov, impermeability, corrosion kuj thiab carbonization tsis kam ntawm pob zeb.
