PISE3, AKASH D. After six months of curing, all the concrete samples exhibited lower sorptivity, due to a longer period of curing allowing the binders to hydrate properly and reduce the capillary pores strength with ages is higher in case of fly ash concrete; such gain is more predominant in case of high volume fly ash concrete than that of low volume fly ash concrete. 1. in 2005 (ACAA. Fly Ash is used in about 50% of ready mixed concrete (PCA 2000). Typical chemical composition of fly ash. Fly ash normally will. 0%-80% replacement of cement by fly-ash Fly ash particles are glassy, spherical shaped “ball bearings” — typically finer than cement particles. The alkaline solutions NaOH and Na 2SiO 3 were forming a gel like substance on reaction with fly ash which contributed for the binding property The addition of fly ash in concrete improves certain properties such as workability, later age strength development and few durability characteristics.

A Review on High Performance Concrete Using Mineral Fly Ash and GGBS with M-60 Grade Concrete Effect of Microsilica and fly ash on the strength of concrete. High Lime fly ash is a type of sub- bituminous fly ash t hat is self -cementing as well as pozzolanic in nature. Call for Papers - International Journal of Science and Research (IJSR) is a Peer Reviewed, Monthly, Open Access International Journal. This paper presents a review on fly ash as prime materials used for geopolymer. One of the practical solutions to economise cement is to replace cement with supplementary cementitious. The addition of fly ash adds value to the cement, and also reduces the OPC contribution to CO2 emissions during concrete production This research paper is carried out the utilization and minimization of solid waste i.e. This research studies the potential fly ash and clay mixture (FAC) as a nuclear shielding material in concrete mixture. of concrete compared to OPC. The fly-ash used in different proportions as a replacement of cement. The effects of durability improving admixture, air content, water-binder ratio, and fly ash replacement ratio on the performance of fly ash concrete are discussed in this paper The goal of this research is to explore the impact of e-waste as a coarse aggregate and fly ash as a filler in the bituminous concrete pavement.Due to increase in the demand for raw materials, there is depletion of raw materials nowadays which make depletion of resources for the future generation.There is a lot of alternative to e-waste and. International Journal of Scientific and Research Publications, Volume 6, research papers on fly ash concrete Issue 2, February 2016 381 ISSN 2250- 3153 www.ijsrp.org MIX DESIGN OF FLY-ASH BASED GEOPOLYMER CONCRETE.
