fis-1997	Rahmani, Kamal; Rahmanzadeh, Belal; Piroti, Saber	Experimental study of the effect of water-cement ratio on compressive strength, abrasion resistance, porosity and permeability of Nano silica concrete	2018	9	.pdf	application/pdf	3919	258	51	The effect of water-cement ratio on abrasion resistance, porosity and hydraulic conductivity coefficient of Nano silica concrete has been studied in this research (paper). Decreasing the water-cement ratio from 0.46 to 0.30 improves the abrasion resistance of Nano silica concrete by 42%, the hydraulic conductivity coefficient of concrete decreases from 28.5⤬10-15 to 1.7⤬10-15 m/s and the porosity of concrete decreases to 13.1%.	cache/fis-1997.pdf	txt/fis-1997.txt
