introduction ? special types of concrete are those with outoftheordinary properties or those produced by unusual techniques. concrete is by definition a composite material consisting essentially of a binding medium and aggregate particles and it can take many forms. ? these concretes do have advantages as well as disadvantages. 3.

in this present experimental study geo cement is developed using high calcium fly ash and used in the production of onepart alkaliactivated binders. at 8–16 percent of the total precursor materials the hcfa was activated with anhydrous sodium metasilie powder and cured in ambient condition. five mixtures of onepart geo paste were intended at a steady w/b proportion.
physical evolution of geo ic minerals derived from metakaolin and synthesized with sodium mixedalkali and potassium activating solutions (na k) during thermal exposure. the geo composites were prepared with 40 v% of fiber reinforcement such as carbon eglass and basalt at the direction of in plain. fiber reinforced geo composites were exposed to the room and elevated

in his four recent keynotes at the geo camp 2014 geo camp 2015 geo camp 2016 and geo camp 2017 prof. j. davidovits explained why alkaliactivatedmaterials are not geo s or why alkaliactivation is not geo ization. we have selected all the sequences that had been dedied to this issue in the gpcamp

concrete is a composite material in which the aggregate is bound together in a matrix with a binder. the composites do not contain a hydrated cement phase although portland cement can be used as an aggregate or filler. concrete composites possess a unique combination of properties dependent on the formulation.
concrete repair is inefficient as generally only manual inspection and repair techniques are used [4 5]. consequently it is necessary to find a nonlabourintensive method to repair concrete from the inside out. ideally concrete should be made in such a way that it is self
