Five fly ash concretes were found to gain considerable strength beyond 28 days when standard cured in water at 20Β°C. However, strength development came to an almost complete stop after 3Β½ years, at what time the fly ash activity factors with respect to concrete compressive strength ranged from 0.86

MLx design of fly ash concrete was attempted by three methods to find the influence of design method on the strength development. The conventional addition replacement method was compared with two other techniques by monitoring the compressive strength at 7, 28 and 91 days. The results suggest that
The optimization of properties of lightweight fly ash aggregates for suitability in high-strength lightweight fly ash concrete production was investigated using response surface methodology (RSM). Design-Expert software was used to establish the design matrix and to analyze the experimental data. Th
