Abstract This watchfulness goal is to decide the beginning and ending binding of geopolymer binders using coconut fiber ash (CFA). Experiments were carried out by comparing effects ratio precursors base activators on binders. The precursor material derived from CFA, which consists 8.24% silicon dioxide, 2.3% diphosphate pentaoxide, 70.6% potassium oxide, 2.25% iron 14.1% chlorine. Using two typ...

India has large resources of natural fibres such as Banana, Khus, Sisal, Korai grass,Talipot, Palm leaf, Coconut, Pineapple, Screwpine, Golden grass, Jute and Sabaiamong others. In the past, trade of the village folk depended on harvesting fibresgrown in their villages. Natural fibers have recently gaining attraction of researchersdue to their low cost eco-friendly and biodegradability characte...

This work aimed to obtain thermoplastic starch composites (TPS) derived from and fibers of babassu coconut. The was prepared with 40% plasticizer (glycerol). underwent chemical treatment alkalinization bleaching. SEM images infrared spectra showed that wax, lignin, hemicellulose were removed the fiber surface. TPS a smooth uniform surface, whereas TPSWF composite (washed fiber) voids between TP...

The use and effectiveness of granular and powder activated carbon made from agricultural waste (coconut shell) in the removal of organic matter in wastewater effluents from a brewery industry were investigated. The effect of process variables such as carbonisation temperature, carbonisation duration and activation temperature on the production and quality of activated carbon was studied. Experi...
