Experimental Studies on Air Entrained Ferrocement Panels with High Volume Fly Ash and Compatibility of its Connection

Abstract

Experimental Studies On Air Entrained Ferrocement Panels With High Volume Fly Ash And Compatibility Of Its Connection  A best practices guide is developed from a synthesis of recent research on high-volume fly ash (HVFA) concrete mixtures. These best practices can be applied by the concrete construction industry to achieve desired properties and to ensure the (high) performance of HVFA concrete mixtures in practice. As such, the report considers all aspects of HVFA concrete production, from the characterization of the starting materials, through mixture proportioning and curing options to achieve desired properties, to the in-place early-age and long-term performance of the concrete in its fresh and hardened states. Both mechanical and transport properties are considered in detail. Perspective is established based on a brief review of current practices being employed nationally.

Conclusion

The results presented in this guide have demonstrated that HVFA concretes can offer substantial performance benefits, in addition to their sustainability advantages in terms of reductions in cost, embodied energy, and CO2 emissions. It must be recognized that HVFA concrete is a different material from conventional concrete and may therefore require new and/or different characterization, production, placement, and finishing procedures than have been conventionally employed by the construction industry. Published research data suggest that when proper attention is given to these concerns, HVFA concretes with equivalent or superior performance to that of the OPC concrete they are replacing can be achieved.
