The invention relates to a process comprising binding silver ions to rice husk ash by adding to the rice husk ash a silver precursor, and reducing the silver ions bonded to the rice husk ash by a reducing agent to obtain rice husk ash with bonded silver nanoparticles.RAUTARAY DEBABRATA...
3.1.3. Oxide composition The results from the XRF analyses of RHA and kaolin are shown in Table 4. The results indicate that, at the firing temperatures considered in this study, the silica content of the rice husk ash ranges from 89 to 5.65%. This is close/or within the range reported...
Meanwhile, the drying shrinkage of steel slag and rice husk ash composite cementations materials is improved. While the water absorption is higher than pure cement.doi:10.1142/9789814651011_0078Ying HanThe Joint Conferences of 2015 International Conference on Computer Science and Engineering Technology (...
Rice huskRice husk ashRice husk is the main byproduct of industrial processing of rice, and is a widely used byproduct in Brazil and worldwide as biomass in energy production, reducing environmental impacts associated with improper disposal. The ash generated in rice husk combustion has potential...
Rice husk ashThe motivation for this study was to find a possible economic alternative for the residual Rice Husk Ash (RHA) as well as a way to mitigate the growing environmental problem in Southern Brazil (illegal deposition of exceeding rice husks and RHA). For this, an investigation was ...
Evaluation of rice husk ash as filler in tread compounds Rice which is one of the largest agriculture crops produces around 22% of rice rusk during its milling process. This material is mainly used as fuel for en... MRS Fernandes,CRG Furtado,AMFD Sousa - American Institute of Physics 被引...

In this work a complete characterization of rice husk ash (RHA) was conducted in order to evaluate mainly the composition and the thermal reactivity in terms of crystalline phase evolution. Moreover, the screening results of the research conducted on the possibility to use RHA as silica precursor...
This paper presents an experimental study on the effects of the incorporation of rice-husk ash (RHA) in cement paste and concrete on the hydration and the microstructure of the interfacial zone between the aggregate and paste. The influence on the compressive strength of concrete is discussed and...
The effect of rice husk ash (WRHA) as a filler in epoxidized natural rubber compounds has been studied. The mechanical properties viz tensile and tear strength were enhanced by the addition of WRHA. The optimum level of WRHA to obtain maximum mechanical properties was achieved at 20 phr after...
