The effectiveness, K, of a fly ash can be defined as the ratio of the amount of cement replaced to the amount of fly ash added, provided the specified requirements of the concrete are maintained. It is generally assumed that the effectiveness of a fly ash can be treated as a constant. This paper pre

Recycled poly(ethylene terephthalate), PET, mainly recovered from plastic beverage bottles, can be used to produce unsaturated polyester resins. In turn, these resins can be mixed with inorganic aggregates (sand and gravel and fly ash waste), to produce polyester concrete (PC). The strength and dura
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
