Cement is a binding material, a substance that sets and hardens independently, and can bind other materials together. In ancient civilization the binding materials were of traditional type such as jaggery, lead, jute, rice husk etc, now in modern civilization cement is main binding materials. The use of concrete containing high volume fly-ash has recently gained popularity as a resource efficie...

Background: Poultry droppings from poultry farms and rice husks obtained from rice milling process are generally considered as wastes and discarded in Nigeria. Although many studies have shown that microbial fuel cells (MFCs) can generate electricity from organic wastes, little or no study have examined MFCs for generating electricity from poultry droppings and rice husk as electrode material. ...

The most outstanding problem militating the production of earth block in Nigeria, is exorbitant prices cement, rice ash replaced with stabilized compressed to carry load. main objective this study was investigate sustainability earthen construction a partial replacement cement using Rice Husk Ash (RHA). RHA bye-product material obtained from combustion husk which consists non-crystalline silico...

The utilisation of rice husk ash (RHA) as an aluminosilicate source in fire-resistant coating could reduce environmental pollution and can turn agricultural waste into industrial wealth. overall objective this research is to develop a rice-husk-ash-based geopolymer binder (GB) fire-retardant additive (FR) for alkyd paint. Response surface methodology (RSM) was used design the experiments work, ...

Alpha amylase (α-amylase) enzyme is used as a thinning agent in the starch hydrolysis and it is widely used in the food processing, paper and textile industries. The intention of the present study was to analyse the α-amylase activity in solid state fermentation and submerged fermentation using immobilized cells of Aspergillus oryzae (A. oryzae) and Bacillus cereus (B. cereus), respectively. Th...
