Kev sib xyaw ua ketau siv rau hauv pob zeb rau ze li ib puas xyoo ua khoom. Tab sis yos rov qab mus rau lub sijhawm thaum ub, qhov tseeb, tib neeg tau paub ntev txog kev siv qee cov khoom ntxiv hauv kev tsim cov ntaub ntawv cementitious. Cov ntaub ntawv pov thawj cov ntaub ntawv uas nyob rau hauv 1885 Europeans twb paub tias hardening regulators, xws li txiv qaub thiab gypsum, tau ntxiv rau pob zeb. Thaum kawg ntawm lub xyoo pua 19th, kev siv calcium chloride yog txhua yam npau taws heev thiab tseem siv niaj hnub no. Los ntawm xyoo 1895, cov dej txuas ntxiv thiab cov yas yas tau ntxiv rau hauv cov pob zeb rau txoj kev paving, uas ua rau muaj kev txhim kho zoo ntawm cov pob zeb.

Cov khoom lag luam raug cai raug pom thawj zaug hauv xyoo 1910. Thaum North America tau tsim nyob rau hauv Tebchaws Meskas hauv xyoo 1930, cov pob zeb ua pob zeb tau khov sai heev vim muaj huab cua txias heev. Txhawm rau txhim kho qhov zoo ntawm cov pavement pob zeb, "vinsa resin" tau siv los txhim kho qhov ua tau zoo ntawm cov pob zeb. poj niam deev. Cov khoom lag luam tshawb fawb tiag tiag yog "Pozzolitn" dej txo tus neeg sawv cev (Pozzolitn), uas tau tshawb fawb tiav thiab tsim los ntawm EW Scxiptrt ntawm MasterBuilder ntawm Tebchaws Meskas hauv xyoo 1935, uas yog tsim los ntawm lignosulfonate hauv cov kua txiv hmab txiv ntoo. Xyoo 1937, Tebchaws Meskas tau tshaj tawm thawj patent rau tus neeg saib xyuas dej txo qis hauv keeb kwm. Nyob rau hauv 1954, thawj batch ntawm cov qauv xeem raukev sib xyaw ua ketau formulated.

Txoj kev siv ntawmkev sib xyaw ua kenyob rau hauv kuv lub teb chaws yog xyoo 1950. Thaum lub sij hawm ntawd, rosin saponified huab cua-entraining tus neeg sawv cev tsim los ntawm cov kws txawj los ntawm lub qub Soviet Union tau qhia. Nws tau siv rau hauv Tianjin Tanggu Tshiab Chaw nres nkoj, Wuhan Yangtze River Choj thiab Foziling Reservoir, thiab ua tiav qee qhov txiaj ntsig. Tom qab ntawd, cov yas yas siv cov kua nplaum pov tseg los ntawm sulfite papermaking thiab khib nyiab zib ntab los ntawm kev lag luam qab zib raws li cov khoom siv raw. Kev siv cov khoom sib xyaw kuj pib los ntawm qhov ntawd.

Kev txhim kho thiab kev siv ntawmkev sib xyaw ua kemuaj qhov tseem ceeb mus ntev. Vigorously tsim thiab txhawb kev siv ntawmkev sib xyaw ua keyog ib txoj hauv kev tseem ceeb los txhawb txoj kev kawm txuj ci ntawm kev tsim kho kev lag luam.

Nyob rau hauv cov txheej txheem ntawm kev tsim kho cov haujlwm, kev siv cov khoom sib xyaw tuaj yeem txhim kho qhov chaw tsim kho kom zoo, pab txhawb kev siv ntau yam khoom siv kho tshuab, txo cov haujlwm ntawm cov neeg ua haujlwm tsim kho, thiab xyuas kom zoo ntawm qhov project. Tsis tas li ntawd, nws kuj tuaj yeem siv rau qee qhov hnyav. Ua tiav cov haujlwm tsim kho hauv ib puag ncig.
