Abstract

Geopolymer concrete is an eco-friendly concrete as it produces less CO2 compared to ordinary Portland cement. The scarcity of natural river sand has led to many investigations to find a substitute for fine aggregates. Pond ash which is an industrial waste, has been used as substitution for fine aggregates. The current paper investigates effect of pond ash gradation on mechanical properties of geopolymer concrete by ANN and MLRA analysis. Various data samples collected from literature were fed into ANN and MLRA tool box in MATLAB and Microsoft Excel respectively to obtain the strength predictions. The outcomes of analysis of ANN and MLRA model showed that ANN and MLRA results match well with experimental data from literature. The predicted strength results of geopolymer concrete having pond ash belonging to zone II exhibited better strength properties than geopolymer concrete having pond ash belonging to Grade I, III and IV.
