Abstract

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.
