Abstract

It is expected that in the near future, the civil engineering community will have to produce structures in harmony with the concept of sustainable development through the use of high-performance materials with low environmental impact that are produced at a reasonable cost. Geopolymer concrete provides one route toward this objective synthesized from the materials of geological origin or by product materials such as fly ash, which are rich in silicon and aluminum. But major disadvantage of geopolymer concrete (GPC) is curing of this concrete is to be carried at elevated temperatures and this concrete is recommended for precast members because of temperature curing. This paper finds solution to overcome these problems in GPC by replacing fly ash with cement and the tests show encouraging results by which this new cement added GPC can be made as Eco-friendly construction material.
