POTENTIAL APPLICATION OF A LOCALLY SOURCED PHOTOCATALYST FOR THE PHOTOCATALYTIC DECOLOURISATION OF METHYL ORANGE IN AQUEOUS SOLUTION [PDF]

Journal of Engineering Science and Technology, 2015
Periwinkle shell ash (PSA) was investigated for its photocatalytic properties in decolourising methyl orange in aqueous solution. The effects of irradiation time, initial dye concentration and PSA dosage on the decolourisation process were investigated ...

Analyzing the Mechanical, Durability, and Microstructural Impact of Partial Cement Replacement with Pumice Powder and Bamboo Leaf Ash in Concrete

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
This study explores the physiomechanical and durability properties of C‐25 concrete by partially replacing cement with blends of pumice powder (PP) and bamboo leaf ash (BLA). The combined amount of major oxides SiO2, Al2O3, and Fe2O3 in PP is 84.59%, while in BLA, it is 74.4%, classifying PP and BLA as class N and F pozzolans.
