Sensitivity of Service Life Extension and CO₂ Emission due to Repairs by Silane Treatment Applied on Concrete Structures under Time-Dependent Chloride Attack

Table 1

Application time, effective duration, and effect of silane treatment.

Silane treatment strategy	Application time		Eff. duration (yrs) (tDUR)	Diffusion coefficient of silane-treated concrete during effective duration	Eff. depth (mm) (xp)
	First (tFIRST)	Sub. (tSUB)
SL1	At year 5	Every 7.5	5		9
SL2

Note. α is the ratio of diffusion coefficient of original concrete to that of silane-treated concrete and is equal to 12%. t_APP is equal to the years 5, 12.5, 20, 27.5, 35, and so on. β is the rate of the deterioration of silane treatment.
