This dispersion in fatigue-life data has, therefore, been a topic of research [10–13] over the last decade.

Various fatigue strength prediction models have also been proposed to predict the fatigue-life of composite materials.

The results reported here on fatigue of PCC and GFRPCC are a part of this larger investigation.

Epoxy resin, LAPOX-B47 along with hardener LAPOX-K46 supplied by Atul Ltd., Mumbai, has been used in this investigation.

The aggregate mix had been optimized based upon the least void content criteria.

A microfiller is also often added to PCC mix to reduce the void content in aggregate mixture and thereby increase the strength of PCC.

Forty-three static flexural tests were also conducted to facilitate fatigue testing.

The most important reason for this is the vibration damping capability of PCC and GFRPCC which is significantly higher than conventional machine building materials like cast iron [4–6].

Ambedkar National Institute of Technology, Jalandhar 144011, India Received 18 January 2014; Accepted 4 March 2014; Published 27 March 2014Academic Editors: M. The fatigue strength prediction model, representing S-N relationship, has been examined and the material coefficients have been obtained for GFRPCC containing 0.5% and 1.0% glass fibres.

It has been observed that the probabilistic distribution of fatigue-life of polymer concrete composite (PCC) and glass fibre reinforced polymer concrete composite (GFRPCC), at a particular stress level, approximately follows the two-parameter Weibull distribution, with statistical corelation coefficient values exceeding 0.90.

Fly ash is a by-product of the coal burning in power plants and is used as a filler because of its easy availability and because of that its usage in PCC is reported to yield better mechanical properties as well as reduced water absorption [24].

F-type fly ash has been used in the ratio of 10% by total weight of PCC in this study.
