Kev tsim kho tshuaj-tseem hu ua cov khoom siv hauv tsev tshuaj- yog cov khoom siv hauv kev tsim kho uas feem ntau tau los ntawm cov khoom siv hluavtaws polymer thiab tau ua haujlwm tshwj xeeb. Cov khoom no suav nrog ntau yam khoom, suav nrog kev tsim kho plastics, coatings, adhesives, waterproofing cov ntaub ntawv, sealants, thiab thermal rwb thaiv tsev cov ntaub ntawv.
Cov ntaub ntawv no muaj qhov zoo sib xws, xws li lub teeb yuag, yooj yim ntawm kev teeb tsa, thiab kev siv hluav taws xob tsawg thaum tsim khoom. Yog li ntawd, lawv tuaj yeem hloov ib nrab rau cov tsoos, lub zog- cov ntaub ntawv siv hauv tsev- xws li steel, ntoo, thiab cement- thiab tau siv dav hauv thaj chaw xws li cov kav dej, qhov rooj, thiab qhov rais mus rau cov txheej txheem thermal rwb thaiv tsev thiab kho cov txheej txheem. Piv txwv li, cov kav dej yas hnyav tsuas yog ib qho -yim ntau npaum li cam khwb cia- cov kav hlau, thaum lub qhov rais yas tuaj yeem txo cov cua sov siv los ntawm 30% mus rau 50%. Tsis tas li ntawd, cov khoom siv tshuaj siv los daws cov teeb meem kev tsim kho, xws li kev sib khi sai sai hauv qhov av los ntawm cov tshuaj grouting los yog txhawb cov av hauv paus.
