FLY ASH MISSION Objective: Confidence building in flyash disposal / gainful utilization technologies Through : Technology Demonstration Projects with participation of industry. Partners : Industry, Power utilities, R&D organisations, User agencies, Academia & Facilitating/ Regulating Ministries/ Departments/ Agencies etc.
FLY ASH UNIT Objective: Focus is being continued on: • Development of new / incremental technologies • Adaptation/large scale application of technologies • Preparation & updation of standards / specifications • Support & facilitation to other Government Ministries / Department
FLY ASH UNIT Current New Initiatives • Use of fly ash in concrete for critical structures such as building and foundation for rolling mills, turbo-generators in power plants, chimneys and cooling towers etc. • Construction of railway embankments with fly ash. • Induction of fly ash in academic curriculum. • Preparation of Base Line Documents for each area of fly ash utilization and management to work as road map for future activities and to aid the policy and strategy planning.
