Performance analysis of solar and solar-infrared dryer of mint and apple slices using energy-exergy methodology
(Elsevier Ltd, 2019)
In this study, double-pass solar air dryer (DPSAD) and infrared assisted double-pass solar air dryer (DPSAIRD) were designed and tested. The effects of using infrared energy have been experimentally investigated to ensure ...
Analysis of drying of melon in a solar-heat recovery assisted infrared dryer
(Elsevier Ltd, 2016)
Infrared drying systems are popular in terms of high heat and mass transfer. By using an infrared dryer, it is possible to catch fast heating and short drying time in comparison to the other drying methods. But it consumes ...
Permeability characteristics of superfine cement-grouted sand
(American Concrete Institute, 2017)
The aim of this research was to investigate the permeability of superfine cement-grouted sand. Initially, rheology of superfine cement suspensions was studied. The sedimentation and the setting time increased but the ...
Effect of hyper-plasticizer additive rates on the properties of polypropylene fibre tempered concretes
(Springer, 2018)
In this study, effect of different rates of hyper-plasticizer additives on the physical and mechanical properties of polypropylene fibre tempered concretes was investigated. The factors of slump and compaction, which are ...
Use of waste concrete in cement production
(Springer, 2018)
Use of waste concrete in tempered cement production was examined in this study. Waste concretes were used in limestone-tempered cement production. In tempered cement production, 5, 10, 15, 20 and 28% milled waste concrete ...
Development of flaw tolerant fiber reinforced cementitious composites with calcined kaolin
(Elsevier Ltd, 2017)
Flaws naturally occur in the structure of the cementitious composites or concrete. When brittle composites (ceramics, concrete) are loaded up to their ultimate capacity, micro-cracks initiate and propagate from these flaws ...
Determination of drying kinetics and quality parameters of grape pomace dried with a heat pump dryer
(Elsevier Ltd, 2018)
Pomace of Hamburg Muscat was dried at temperature of drying air 45 °C and different air velocity (1.5, 2.0 and 2.5 m/s) in open-loop heat pump (HP) and laboratory-type closed-loop dryer (as a control). In the HP dryer, it ...
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 ...
