This session will disseminate information related to slender reinforced concrete, known as “tilt-up” or “site-cast tilt-up concrete.The responsibilities for parties involved in a repair project may be significantly different than those traditionally encountered in new concrete construction., serves as an interim to the Bond in Concrete conference series, held in Europe every 10 years.Various presentations will highlight the following information: 1) important changes required to development and lap splice provisions for reinforcement; 2) new works and developments as related to the modelling of bond between reinforcing steel and concrete; and 3) the results of recent experimental studies relating to lap splicing of straight bars.The new ACI 562 Code Requirements for Assessment, Repair, and Rehabilitation of Concrete Buildings and anticipated ACI 563 Specification identify requirements for the Licensed Design Professional and the contractors’ specialty engineer during repair programs.
Fly ash quality can be improved through various processing techniques.
Both experimental and analytical investigations are of interest.
The session brings to light recent research findings and provides an opportunity to discuss present challenges and technical demands.
To meet market demand for quality and quantity, beneficiation is an increasing necessity.
In addition, reclaiming fly ash from disposal in landfills and ponds is becoming more common and often requires beneficiation.
