Performance of novel chemical grout in treating sands
(American Society of Civil Engineers (ASCE), 2017)
A new chemical grouting formed by sodium silicate-boric acid mixtures was introduced. Initially, suitable sodium silicate and boric acid contents in the grout mixtures were studied. Gel time, initial viscosity, and syneresis ...
UCS properties of superfine cement-grouted sand
(American Society of Civil Engineers (ASCE), 2016)
This research focused on the strength characteristics of superfine cement-grouted sand with various gradations and relative densities. At first, grout properties of superfine cement suspensions were studied. The sedimentation ...
Ultrafine Portland cement grouting performance with or without additives
(Springer Verlag, 2014)
The aim of this experimental study was to investigate the penetrability of ultrafine Portland cement suspensions with or without additives into sand specimens and the strength and permeability of grouted sand samples. It ...
Mechanical characterization of ruthenocuprates by nanoindentation technique
(Springer New York LLC, 2014)
The nanomechanical properties of RuSr 2 RECu 2O8 (RE = Eu, Gd and Ho) prepared by ammonium nitrate melt technique (ANMT) were investigated using nanoindentation technique. The indentation load–displacement curves of the ...
A comparative investigation of the effect of honeycomb core on the latent heat storage with PCM in solar air heater
(Elsevier Ltd, 2019)
The aims of this study were to comparatively investigate the effect of using PCM and honeycomb as the internal fin structure in the PCM panel on the thermal performance of solar air heater. The tests performed at six air ...
Thermal performance of flexible air duct using a new absorber construction in a solar air collector
(Elsevier Ltd, 2019)
This paper presents the comparative experimental energy and exergy analysis of a solar air collector (SAC) with flexible aluminum foil duct and conventional flat plate SAC, with and without glazing. Effect on performance ...
Syneresis effect on the permeability of chemically grouted sand
(Geological Society of London, 2016)
The aim of this research was to investigate the permeability of sodium silicate grouted sand specimens having various gradations and relative densities. Initially, rheological properties of sodium silicate grouts were ...
A betonului autocompactant increasing the tensile strength of fiber reinforced self-compacting-concrete, and effects of fiber type and orientation
(Fundatia Serban Solacolu, 2017)
In this study, the effects of using fiber in self compacting concrete (SCC) on flow parameters, tensile and compressive strength of concrete were investigated. Unit weight, air content, slump flow, J-ring, V-funnel tests ...
Development of heat pump and infrared-convective dryer and performance analysis for stale bread drying
(Elsevier Ltd, 2016)
This experimental study aims to develop a heat pump dryer (HPD) and an infrared dryer (IRD) also the comparative empirical analyses of these two methods and to analyze the drying kinetic of stale bread sliced 15 mm thickness ...
Performance analysis of heat pump and infrared–heat pump drying of grated carrot using energy-exergy methodology
(Elsevier Ltd, 2017)
In this study, a hybrid drying system that combines all of the advantages of different drying methods was developed. This study aims to compare experimental results of a heat pump dryer (HPD) and an infrared assisted heat ...
