The durability of the self compacting concrete is one prominent areas concern in recent years since it has become prevalent due to its ease handling construction industries. However, there a lack detailed study M-sand with polypropylene fibres literature. In this paper, made by Portland pozzolana cement natural sand and M-sand, different percentages volume fraction (0%, 0.1%, 0.15% 0.2%) thorou...

in order to investigate the effects of nitrogen application rates and different planting beds on yield and yield components of garlic (allium sativum l.), a field experiment was conducted as split plot based on a randomized complete block design with four replications at the agricultural research station, azad university of torbat-e-jam, iran, during 2009-2010. three nitrogen application rates ...

In this study, the pressure drop for the binary mixtures of particles differing in size and density in a pseudo-2D spouted bed was experimentally studied. A binary mixture of solid particles including sand, Gypsum, and polyurethane was used in the experimental setup. Effects of static bed height, cone angle, particles diameter, and a particles weight fraction on the bed pressure drop were e...

Numerous publications on the transport of pollutants in a fixed bed, particular treatment waters still use two-parameter models: capacity parameter measuring delay breakthrough curve (CP) and transfer kinetics to translate dispersion observed (Thomas model Yoon-Nelson model), The authors totally neglect role hydrodynamic which however largely contributes spread curves thus adjustments made anal...

Abstract In the present paper, effects of diameter, bed slopes, and roughness on free overfall flow semi-circular channels were investigated experimentally. For this purpose, three models with built installed in a 6m long laboratory flume. These 250 cm had varying diameters 160, 200, mm. Four different slopes (S) used each these (0, 0.004, 0.008, 0.012). slope, sand particle sizes to roughen (1...

effect of scale on the hydrodynamics of gas-solid fluidized beds was investigated in two fluidized beds of 152 mm and 78 mm in diameter.  air at room temperature was used as the fluidizing gas in the bed of sand particles. the radioactive particle tracking (rpt) technique was employed to obtain the instantaneous positions of the particles at every 20 ms of the experiments. these data were used ...

Sand (i.e., < 2 mm) infiltration into a gravel bed is recognized to affect sediment dynamics of coarser fractions entrainment and transport rate), near-bed velocities, morphology, pose significant engineering ecological issues. Local hydraulics, dynamics, sand the matrix are related mutually each other in gravel-bed rivers. However, relatively little research has been done explore mobile under ...
