Progressive utilisation prospects of coal fly ash: A review.

Science of the Total Environment, 2019
The rapid surge in global energy needs has paved way for the development of various alternatives to natural resources every now and then. However, dependence on coal-based energy has not reduced greatly. Thus, massive quantities of coal fly ash (CFA) are

Analyzing the compressive strength of green fly ash based geopolymer concrete using experiment and machine learning approaches

, 2020
In this research, two different machine learning approaches are proposed for predicting the compressive strength of fly ash based geopolymer concrete. Experimental work with a total of 335 mix proportions were conducted to produce the data for training ...

Can incineration completely eliminate plastic wastes? An investigation of microplastics and heavy metals in the bottom ash and fly ash from an incineration plant.

Science of the Total Environment, 2021
The content of (micro)plastics and heavy metals were investigated in the fly ash, bottom ash and surface soil samples from a municipal solid waste incinerate plant. The abundance of microplastics was 23, 171, and 86 particles/kg dw, respectively.

Chloride diffusion resistance and chloride binding capacity of fly ash-based geopolymer concrete

, 2020
This study evaluated the chloride diffusion resistance of low-calcium fly ash-based geopolymer concrete through electrical and bulk diffusion techniques. The geopolymer concretes were prepared using 12 different heat curing conditions; three temperatures
