Effect of W/C Ratio on Durability and Porosity in Cement Mortar with Constant Cement Amount

Table 6

Regression analysis for various ranges of porosity and w/c ratios.

Pore diameter range	𝑌=𝐴(𝑋−1)+1
	𝑌: gradient of normalized pore change
	𝑋: normalized w/c or water content
	𝐴	𝑅^2
~0.01 μm	4.3682	0.7246
0.01~0.1 μm	2.3352	0.9839
0.1~1 𝜇m	0.3412	0.1506
0.1~10 𝜇m	0.9321	0.9765
10 μm~	0.5489	0.2400
