A Minimum Flexural Reinforcement Puzzle
Analyses of the minimum flexural reinforcement requirements in ACI 318-14 show that updates are needed. Expressions should include the effects of concrete strength, and expressions for lower strength steels should be abandoned.
Fly Ash Concrete with Low Portland Cement Content
Concrete mixtures with high volumes of fly ash can exhibit retarded setting and strength development. Various admixture and cement-fly ash combinations were evaluated to determine the impacts of cement alkali and fly ash calcium oxide contents on setting time and 1-day compressive strength.

From Research to Reality
A panel of experts debated the use of performance-based specifications at the 123 Forum session at The ACI Concrete Convention and Exposition – Spring 2016 in Milwaukee, WI. The general consensus was that performance-based specifications have great potential as alternatives to prescriptive specifications, rather than complete replacements.
Products & Practice Spotlight: Solving the Slab Moisture Issue
When used as a concrete admixture, sodium silicate reacts with the calcium hydroxide and the free water in the mixture to form C-S-H gel. The gel serves as an internal curing medium, bleed channels and pores are drastically minimized, and vapor transmission is dramatically reduced.
