Kev Ntsuas Cov Khoom Siv Hauv Tsev

(1) Cov khoom lag luam: cov khoom sib xyaw ua ke, cov khoom sib tsoo cov cement, cov khoom siv tshuaj khib nyiab, cov tshuaj tiv thaiv dej, cov tshuaj tiv thaiv kab mob, cov tshuaj tiv thaiv kab mob, cov tshuaj tiv thaiv thaum ntxov, cov dej txo qis (polycarboxylates, naphthalene series, thiab lwm yam), cov khoom siv cua nkag, cov neeg ua haujlwm nthuav dav, cov neeg ua kom nrawm, cov dej tso tawm cov neeg ua haujlwm, cov tshuaj tua kab mob, cov tshuaj tua kab mob, cov tshuaj tiv thaiv kab mob, cov tshuaj tua kab mob, cov tshuaj tua kab mob, cov tshuaj tua kab mob, cov tshuaj tua kab mob, cov tshuaj tua kab mob, cov tshuaj tua kab mob, cov tshuaj tiv thaiv kab mob additives, putty additives, txheej additives, thiab lwm yam.

(2) Cov xwm txheej siv tau: kev tswj xyuas zoo ntawm cov khoom siv hauv tsev tsim khoom, kev lees txais cov khoom siv raw, kev hloov kho ntawm kev tsim kho engineering, kev ntsuas kev ruaj ntseg thiab kev nyab xeeb, kev sim ua raws li ib puag ncig, kev ntsuas kev txiav txim siab.

(1) Cov tsos mob thiab lub cev thiab tshuaj lom neeg
Cov tsos, xim, mob, ntom, viscosity, pH tus nqi, cov ntsiab lus, cov ntsiab lus noo noo, fineness, insoluble teeb meem, chloride ion ntsiab lus, alkali ntsiab lus, sulfate cov ntsiab lus, stability, cia stability, compatibility nrog cement / aggregates.

(2) Kev ua haujlwm ntawm cov cement / pob zeb / mortar
Teem sijhawm (thaum pib, qhov kawg teeb tsa), flowability, expansion, slump poob, dej txo tus nqi, los ntshav tus nqi, huab cua cov ntsiab lus, compressive zog, flexural zog, impermeability, shrinkage npaum li cas, expansion npaum li cas, Frost tsis kam, thaum ntxov zog, lig zog, hydration tshav kub, daim ntawv cog lus zog, dej tuav, thiab workability.

(3) Durability kev ua tau zoo
Anti carbonization kev ua tau zoo, tsis kam mus rau chloride ion nkag mus, tsis kam mus rau sulfate corrosion, alkali aggregate cov tshuaj tiv thaiv inhibition nyhuv, kev laus tsis kam, dej tsis kam, thiab corrosion kuj.

(4) Ib puag ncig thiab kev nyab xeeb ntsuas
Dawb formaldehyde, ammonia VOC, Benzene derivatives, hnyav hlau ( lead, cadmium, chromium, mercury, arsenic), radioactivity, corrosiveness, mob toxicity, thiab txwv tsis pub muaj teeb meem tshuaj.
