IS GEOPOLYMER CONCRETE A SUITABLE ALTERNATIVE TO
Dept of Civil Engineering
Geopolymer concrete is the result of the reaction of materials containing aluminosilicate with concentrated alkaline solution to produce an inorganic polymer academic research,geopolymer concrete has yet to enter the mainstream of concrete construction.Most applications to date have been in the precast industry using accelerated curing.However, the use of geopolymer concrete in ready mixed applications is increasing;building on the information currently available and motivated by the considerable sustainability benefits of using a binder system composed almost entirely of recycled materials.A wide range of different geopolymer binder systems are available and discussed in the literature.This creates a potential problem of the satisfactory performance of particular proprietary geopolymers being used to support the use of unproven products under the generic label of geopolymer concrete.The supplying a proprietary geopolymer concrete for both precast and in-situ applications.This paper presents data on the engineering properties of this concrete and examples of its application. The paper demonstrates that this particular geopolymer concrete complies with the relevant performance requirements of the Indian Standards and thus provides the Engineer with a viable alternative to Portland cement based concrete allowing greatly reduced the embodied energy and carbon dioxide footprint.
