The objective of this study was to determine effect of germination on total anthocyanin content (TAC) and antioxidant activity of colored rice (Oryza sativa L). The normal, non-waxy rice variety Phitsanulok 2 was used as a control and two pigmented rice including black glutinous rice (local name Niew Dam), and black non-waxy rice (local name Hom Nil) were used in this study. Rough rice and dehu...

The rich husk is an agricultural waste of rice cultivation worldwide, which highly in amorphous silica. Rice obtained from Dagiri was pyrolysed at 750 ? to give white ash (RHA) further treated with acid (ARHA). reacted sodium hydroxide 90 for 2 hours 30 min produce Sodium silicate crystals. silicates synthesized the study were characterized some physicochemical parameters. Their structural and ...

Rapid increase in construction activities leads to active shortage of conventional construction materials due to various regions. Concrete is most widely used construction material. Cement, sand & granite stone are the constituents of the concrete. Researches were researching for cheaper materials that can be used as substitute for these materials. In this context an experimental study was carr...

Rice Husk Ash (RHA) is natural Pozzolan containing reactive silica and/or aluminum. When the material is mixed with lime in powdered form and in the presence of water, it will set and harden like cement. This work uses Osadebe’s optimization model to optimize the shear modulus of concrete made from RHA. The strengths predicted by the model are in good agreement with their corresponding experime...
