Sirimanna, Chamila Sampath and Lokuge, Weena and Islam, Md Mainul and Aravinthan, Thiru (2012) Compressive strength characterization of polyester based fillers. In: PFAM 20: 20th International Symposium on Processing and Fabrication of Advanced Materials, 15-18 Dec 2011, Hong Kong.
This paper investigates the compressive properties of polyester based fillers with different proportions of resin, sand and fly ash. The research program aims at developing a polymer based filler for a glass fibre reinforced polymer (GFRP) tube to be used as a structural rehabilitation system. It has been initiated to improve fundamental understanding of this material and to provide the knowledge required for its broad utilization. In this development, sample trial mixes were considered based on several weight percentages of polyester resin, fly ash and sand. These weight percentages were selected after analyzing volumetric properties of sand. The effect of resin (binder), sand and fly ash contents on the compressive strength of polyester based fillers with respect to age is reported. It has been found that at the age of 7 days all the batches reached about 90% of the compressive modulus. The experimental compressive stress-strain curves reported here were compared with established analytical models for normal strength concrete.
