Abstract
The effect of water-cement ratio on abrasion resistance, porosity and hydraulic conductivity coefficient of Nano silica concrete have been studied in this research (paper). The compressive strength of concrete in a particular temperature is related to two factors: water-cement ratio and density. 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%. The abrasion depth increases gradually by increasing the water-cement ratio from 0.30 to 0.46.
Highlights
Concrete dams are strategic structures due to their fundamental role at economical system of a country
The main obtained results in the present article showed that the abrasion resistance of Nano silica concrete increased by decreasing of water-cement ratio
By reducing the water-cement ratio from 0.46 to 0.30 at Nano silica concrete specimens, the abrasion resistance of concrete improved by 42%
Summary
Concrete dams are strategic structures due to their fundamental role at economical system of a country. Abrasion resistance; Compressive strength; Concrete; Permeability; Water-Cement Ratio. The effect of water-cement ratio on abrasion resistance, porosity and permeability of Nano silica used in making durable concrete, were considered as an effective factor on strength and performance of these concrete structures (Felekoğlu et al, [9]; Bilodeau & Malhotra [10]).
