The performance of a sustainable green concrete with fly ash (FA), rice husk (RHA), and stone dust (SD) as partial replacement cement sand was experimentally explored. FA RHA have high silica content, are highly pozzolanic in nature surface area without any treatment. These by-products show filler effects, which enhance concrete’s density. Results showed that the materials good hydration behavi...

Present study dealt the removal of Cr(VI) in a tannery industry wastewater using rice husk silica powder as an adsorbent.The experimental investigations have been carried out by using rice husk silica powder for different adsorption dosage, different contact time and different pH against the initial Cr(VI) concentration of 292 mg/L. The maximum percentage removal of Cr(VI) in a tannery industri...

With an annual production around 1.6 million tons, Côte d’Ivoire (Ivory Coast) is still today the world’s largest producer of cocoa beans. This co-generates about 16 million tons of cacao pod husks which are usually left unutilized in plantations to rot, thereby becoming a significant source of disease inoculums. As a way of solving the environmental problem posed by this agrowaste and adding v...

ADEROLU, Ademola Zaid, Eustace. A. IYAYI and Abiodun A. ONILUDE, 2007. Changes in nutritional value of rice husk during Trichoderma viride degradation. Bulg. J. Agric. Sci., 13: 583-589 Possible improvement in nutritional status of rice husk using Trichoderma viride a fungus was investigated over a period of 40 days. Proximate composition was significantly (P<0.05) improved with microbial treat...

This paper assesses the feasibility of two industrial wastes, fly ash (FA) and rice husk ash (RHA), as raw materials for the production of geopolymeric pastes. Three typologies of samples were thus produced: (i) halloysite activated with potassium hydroxide and nanosilica, used as the reference sample (HL-S); (ii) halloysite activated with rice husk ash dissolved into KOH solution (HL-R); (iii)...

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 defluoridation of ground water is regarded as one of the key areas of attention among the universal water community. The present investigation deals with fluoride removal from aqueous solution by thermally activated biosorbents prepared from banana (Musa paradisiaca) peel and coffee (Coffea arabica) husk. Fluoride ion selective electrode was used for the determination and monitoring of fluo...

The authors aimed to examine whether nonparticipation in a population-based health study was associated with poorer health status; to determine whether specific health problems were overrepresented among nonparticipants; and to explore potential consequences of participation bias on associations between exposures and outcomes. They used data from the Hordaland Health Study (HUSK), conducted in ...
