Mechanical properties for cast steel are generally lower than wrought steels with the same chemical composition. Rice husk ash consists of the following: Cellulose (C 5 H 10 O 5) Lignin (C 7 H 10 O 3) Hemicellulose; SiO 2; Holocellulose; These are compounds within them in common. The composition of the technical Committee responsible for the formulation of this standard is given in Annex C. Rice husk ash 5 a) Reactive silica shall not be less than 80 percent when tested as per IS 3812 (Part 1) comply with the chemical requirements given in Table 2. Rice husk affects the efficiency of ration use and must be fermented to improve the nutritional value 2. Degradation. The formed rice husk ash is treated with Sodium hydroxide (NaOH) and Hydrochloric acid (HCl) to produce silica. Produced during rice milling, the rice husk is already dried and accumulated at the factory. The rice husk contains a significant amount of silicon dioxide 14.8%. Result showed significant improvement in growth and biochemical parameters of plants as compared to control plants treated with uncomposted organic fertilizer. It is one of the oldest human-made foods, having been of significance since the dawn of agriculture, and plays an essential role in both religious rituals and secular culture. Proximate analysis of rice husk was measured by ASTM method . Coir (/ k r /), also called coconut fibre, is a natural fibre extracted from the outer husk of coconut and used in products such as floor mats, doormats, brushes, and mattresses.
