From: AHP-Based Evaluation Model for Optimal Selection Process of Patching Materials for Concrete Repair: Focused on Quantitative Requirements

1st level	2nd level	Global weights
1st level	2nd level	Unstandardized	Standardized^a
Chemical requirement (L:.417); R11	Alkali resistance (L:.081); R21	0.0250	0.034
	Chloride permeability (L:.342); R22	0.1070	0.142
	Electrical resistivity (L:.577); R23	0.1800	0.240
Physical requirement (L:.583); R12	Bond strength (L:.219); R24	0.0960	0.128
	Compressive strength (L:.057); R25	0.0250	0.033
	Drying shrinkage (L:.396); R26	0.1730	0.231
	Elasticity (L:.089); R27	0.0390	0.052
	Tensile strength (L:.085); R28	0.0370	0.049
	Thermal expansion (L:.154); R29	0.0680	0.090

^aThese values were normalized by dividing the global weight of each PEI into the sum of entire global weights.
