The RS used conforming to Zone2 according to IS: 383 and has specific gravity and bulk density as 2.65 and 1.45 gram/c.c. respectively. Thus geopolymer concrete with fly ash and GGBS
Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pitrun gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural
Mix Design of Fly Ash Based Geopolymer Concrete Abstract. Geopolymer is a new development in the world of concrete in which cement is totally replaced by pozzolanic materials like fly ash and activated by highly alkaline solution s to act as a binder in the concrete mix.
