The effects of chemical attacks on physical and mechanical properties of concrete produced under cold weather conditions
(Elsevier Sci Ltd, 2014)
This study investigates the effects of corrosive conditions on the physical and mechanical properties of concrete produced in cold weather. 30% calcium nitrate and 5% hydroxyethylaminemixture (HEA) were used as additives ...
Investigation of freeze-thaw effects on mechanical properties of fiber reinforced cement mortars
(Elsevier Sci Ltd, 2014)
Fibers are used for improving some properties of conventional concrete (which is a brittle material) such as tensile strength, abrasion resistance, absorption and crack control. This study investigates the usability of ...
Strength and ultrasonic properties of cemented paste backfill
(Elsevier, 2014)
This paper presents the strength (UCS) and ultrasonic pulse velocity (UPV) properties of cemented paste backfill (CPB) produced from two different mill tailings (Tailings T1 and T2). A total of 240 CPB samples with diameter ...
Effect of different surface oxidation treatments on structural, mechanical and tribological properties of ultrafine-grained titanium
(Elsevier Science Sa, 2014)
Four different surface oxidation treatments, so-called, anodizing oxidation (AO), micro-arc oxidation (MAO), plasma oxidation (PO) and thermal oxidation (TO), were applied to ultrafine-grained (UFG) pure titanium produced ...
A New Approach Stereo Based Palmprint Extraction in Unrestricted Postures
(IEEE, 2014)
Regarding the palms recognition system studies, despite achieving a high success rate, hygiene problems in systems with contact and problems arising from changes in the alignment of the hand pose in non-contact ones have ...
Preparation of a new sorbent, cetyltrimethylammonium bromide (CTAB)-modified obsidian, for the separation, preconcentration of Pb(II), Cd(II) ions in food and water samples
(Perkin - Elmer Corp., 2014)
Cetyltrimethylammonium bromide (CTAB)-modified obsidian (CTAB-OB) was utilized as a new sorbent for the separation and preconcentration of Pb(II) and Cd(II) ions by solid phase extraction in some environmental samples prior ...
