Abstract

This paper will present the results of tests on the diffusion properties of the migrating inhibitor DME and KCR. The tests were done by determining the distribution of concentrations of inhibitors in concrete, and then the values of a reliable diffusion coefficient were calculated on the basis of the solution to the reverse-task diffusion equation. Inhibitors have shown very good diffusion properties, which were about 5 rows better than the properties of the inhibitors on the market. Inhibitors DME and KCR were able to quickly penetrate deep into the concrete through the entire thickness of reinforcement concrete cover.

Organinių medžiagų difuzija betone, stabdanti armatūros koroziją

Santrauka. Straipsnyje pateikti eksperimentiniai difuzijos savybių rezultatai naudojant DME ir KCR inhibitorius. Atliekant bandymus buvo nustatytas inhibitorių koncentracijos pasiskirstymas betone ir patikimos difuzijos koeficiento vertės buvo apskaičiuotos sprendžiant atvirkštinį difuzijos lygties uždavinį. Inhibitoriai parodė labai geras difuzijos savybes, lyginant su kitų rinkoje esančių inhibitorių savybėmis. Inhibitoriai DME ir KCR turi savybę greitai ir giliai įsiskverbti į apsauginį betono sluoksnį.

Reikšminiai žodžiai: betonas, inhibitorius, korozija, difuzija, apsauga, armatūra, gelžbetonis.
