Abstract: Increasing pressures from governments word-wide to reduce carbon dioxide emissions has forced many industries to seek greener, more environmentally-friendly solutions to many of their products. The report that is to follow will report the findings of the strength of geopolymer concrete using recycled aggregate. This report is unique in a sense that it will be exclusively intended for Singapore as the experiment will be carried out using locally sourced materials. The mixture used and tested will remain consistent with past reports publish by academics at Curtin University of Technology, namely; D. Hardjito and B. V. Rangan, S. E. Wallah and B. V. Rangan and P. Sarker. The consistency is held in terms of percentage composition of materials, the variation lies within the difference in properties affecting the quality of the locally sourced materials. Attempts to produce an acceptable geopolymer concrete were unsuccessful as such, the scope of the project was revised. The final scope focused on an OPC based concrete with the addition of 25% slag powder. The variation in this mix design lies with the aggregate compositions; whether natural, recycled or a combination. The mix design was based on a recent paper published by P.Dinakar in ACECON2003, Proceedings of the 2rd Asian Conference on Ecstasy in Concrete held December 2010.
