The high need for polymeric materials and the availability of agro-industrial wastes, such as rice production chain, demand development technologies to obtain composites based on these waste materials. Therefore, this work aims develop using low density polyethylene (LDPE) a polymer matrix husk or ash, prepared by micronization in whirlwind mill, reinforcing fillers. processing was carried out ...

drain envelopes play significant roles in the performance of drainage systems due to theirreduction in letting sediments into the drainpipes and also because of an increase in thehydraulic conductivity of soil around the drainpipes. throughout the present research, theeffect of a one 1000 hour flow on dual envelopes consisting of geotextile as a means ofimproving the hydraulic gradient and rice...

due to the important role of subsurface drainage in managing the ground water level, there are many researches focused on finding a new and more economic way to develop subsurface drainage technologies. lack of proper drainage system in northern iran has caused huge implantation of rice and it is impossible to have second implantation in this region. one reason of insufficiency of current drain...

This study comparably assessed the pozzolanic effect of silica fume (SF) and ground rice husk ash (RHA) as supplementary cementing materials on the properties of blended cement pastes and concretes. A commonly commercial silica fume (SF) and locally-produced rice husk ash (RHA) samples with two finenesses (one with larger size than cement and the other with smaller size than cement) were used i...

Moringa oleifera, a tree indigenous in tropical and sub-tropical areas, has been widely used in water purification in many low-income regions such as Africa, India, and Asia. Its seeds are known to contain proteins that possess coagulating and antimicrobial properties but its use in water treatment is compromised by the corelease of soluble organics in the seeds. These organics can serve as foo...

This study selected solid wastes, such as rice husk ash (RHA), inactive Saccharomyces cerevisiae powder (ISP), and rice husk (RH), as the potential adsorbents for the removal of Fe(II) and Mn(II) in aqueous solution. The structural characteristics, functional groups, and elemental compositions were determined by scanning electron microscope (SEM) and Fourier translation infrared spectrum (FT-IR...
