Synthesis and Applications of Conductive Polyaniline Rice Husk Ash Silica Nanocomposites: A Comprehensive Review | Chapter 9 | Chemistry and Biochemistry: Research Progress Vol. 4

Recently, the development of Nanotechnology, Nanoscience and Nanomaterial have received more attention following its optical, mechanical, electrical and chemical properties. Nanostructures have a prominent place in Nanotechnology since more space can be used in different applications. In the past decades, a class of conductive polymers became famous because of their mechanical and electrical properties. Polyaniline is a conductive polymer popularly known as an environmentally stable and highly adjustable polymer given in an application form of powder, membranes or loose fibres. Low-cost polyolefin and large-scale production are widely used in broad applications. Rice Husk Ash (RHA) is the by-product of the rice mill industry considered as waste material. Many types of research focused on RHA target the highly contained silicate to be converted to silica after Rice Husk (RH) pyrolysis undertaken in a furnace with a temperature of (800˚C). The sol-gel technique offered a simple route in producing silica from RHA, where 3- (chloropropyl) triethoxyscilane (CPTES) is used to convert the RHA into high-quality silica. Polyaniline/Rice Husk Ash Silica Nanocomposite (PANI/RHACCl (SiO2)NCs) are prepared via chemical oxidative polymerization and can be used in various applications such as supercapacitors, pseudocapacitors, coatings, metal absorption, chemicals, encapsulation of light-emitting organs, proton exchange membrane, diffusion membrane, devices Sensor, Nanoelectronic flexible devices, as well as drug delivery. Results have shown that PANI encapsulates SiO₂ Nanoparticles with a very powerful impact on Nanocomposite morphology.

Mechanical Properties of Compressed Stabilised Earth Blocks with Rice Husk Ash| New Visions in Science and Technology Vol. 5

The purpose of this study was to see if Rice Husk Ash (RHA) could be used as a partial replacement for cement in clay soil incompressed earth blocks. The percentage of rice husk ash ranged from 0 to 2.5 percent, 5 percent, 7.5 percent, 10 percent, and 12.5 percent. The blocks admixed with 10% rice husk ash had the highest compressive strength of 1.90 MPa. Water absorption increased continuously as the proportion of rice husk ash increased, with a value of 8.55 percent for the block with 12.5 percent RHA. As the percentage of rice husk ash in the blocks increased, the unit weight of the blocks fell.

Research on Utilization of Waste Materials in Soil Stabilization | Chapter 11 | Emerging Trends in Engineering Research and Technology Vol. 3

Soil strength plays a vital role in the construction field. The main purpose of this project is to stabilize red soil with the help of various waste materials. The waste materials used are rice husk ash, lime, ground granulated blast furnace slag and coconut coir fiber. These waste materials have been mixed with the soil in the ratio 10%, 20% and 30% and subjected to various tests Specific Gravity Test, Sieve Analysis Test, Plasticity Index Test, Standard Proctor Test, Unconfined Compression test and California Bearing ratio test. A comparative increase in soil strength was found with all the waste materials. Thus, ultimately the soil is stabilized with the help of these waste materials.
