Recycled concrete aggregate (RCA) possess high water absorption, due to the porosity of attached hardened cement paste they contain. Fine particles RCA are composed larger amounts paste, which makes their valorization even more difficult in or mortar. One way valorize these fine could be use them as mineral addition, however absorption coefficient has determined, is tricky for powders. The obje...

throughout the present research, squash (cucurbita pepo) slices (0.4 cm thickness and 4 cm diameter) were blanched in a steam chamber for 4 min. following cooling to room temperature, the squash slices were dehydrated by use of a hotair dryer, under air temperature of 60°c up to moisture content of 0.1065 kg h2o per kg d.m. squash slices of specified weights were rehydrated by immersion in dist...

Some landslides move imperceptibly downslope, whereas others accelerate catastrophically. Experimental landslides triggered by rising pore water pressure moved at sharply contrasting rates due to small differences in initial porosity. Wet sandy soil with porosity of about 0.5 contracted during slope failure, partially liquefied, and accelerated within 1 second to speeds over 1 meter per second....

Water sorption isotherms and effective moisture diffusivities were determined at 20 8C for sponge cakes at high water activity as a function of their initial porosity, in the range 86 and 52% (0 g/g dry basis fat content), and of their fat content, ranging between 0 and 0.30 g/g dry basis (67% initial porosity). The equilibrium moisture values were not affected by food structure and decreased w...

effect of sucrose replacement with date syrup powder on physiochemical properties of sponge cake such as specific gravity, volume, apparent density, solid density, porosity, symmetry, moisture content, water activity, crust color and textural firmness was studied. batter specific gravity of the control sample was higher than that of other samples. sucrose replacement with 100% of date syrup pow...

Water and solute flux from the subsurface drains of macroporous agricultural fields are simulated using two-dimensional single-porosity and dual-porosity models. Field-averaged (i.e. effective) parameters are calibrated from drainage outflow and validated for water flow and the transport of non-reactive solutes applied at discrete locations on the field. Both the singleporosity and the dual-por...

Cementation factor is a critical parameter, which affects water saturation calculation. In carbonate rocks, due to the sensitivity of this parameter to pore type, water saturation estimation has associated with high inaccuracy. Hence developing a reliable mathematical strategy to determine these properties accurately is of crucial importance. To this end, genetic algorithm pattern search is emp...

dry beans are rich sources of dietary fiber and phytochemicals such as flavonoids and phenolics that exhibit good functional properties. in current study line, cooking and soaking time effects were investigated on water absorption, splitting and texture properties of different iranian red kidney beans to determine the best lines and the best soaking time for industrial use. d81083 line showed t...

qualitative analysis of petroleum reservoir rocks is still one of the most important topics of core laboratories and directly affects hydrocarbon-in-place, fluid flow, and prediction of field performance. magnetic resonance imaging (mri) as a non-invasive, millimeter resolution technique which only images fluids in porous media fits this purpose perfectly. magnetic resonance is a radio frequenc...
