1 Ashish Dubey X            
David Flax   X       My response to committee responses:
Page 2, Line 83 - Jobsite added water is only one of the many ways that there can be too much water and too high of a w/c ratio. Other culprits include wash water left in the truck, different aggregate moistures as the day proceeds and other areas of the aggregate pile are used, driver using too much water to wash down the hopper before leaving the plant, driver adding water out of sight of the inspector, etc.

Page 13, Line 532 - If macro synthetic fibers are not listed under reinforcement and only steel reinforcement is listed, the implication is that only steel is reinforcement. The most common way I see this handled in specs is to add the macro synthetic under reinforcement and to add the micro fibers in with the admixtures. Micro fibers should not be considered structural reinforcement and are normally used only for the control of plastic and crazing cracks. Macro fibers can take the place of the rebars in many applications including all slabs on grade.

Page 18, Line 712 - Manufacturer literature always says something to the effect of applying evenly or uniformly, however if you have ever been at a jobsite seeing a curing compound applied with a Hudson type sprayer you know that it will be neither even or uniform. That is why backrolling to evne out the coverage is critical to getting a good cure.
 
 
David Rodler X            
Horace Willis X            
James Hicks   X       The ballot does not include ASTM C 1543.
ASTM C-1543 Standard Test Method for Determining the Penetration of Chloride Ion into Concrete by Ponding, has been shown to be an excellent means of establishing durability. "The transport properties of concrete are a primary element in determining the durability of concrete. In this study, several new test methods that directly measure aspects of fluid and ionic transport in concrete were examined. ASTM C 1543... provides the means for determining the apparent chloride diffusion coefficient, which is the controlling parameter for chloride ion migration in saturated pore systems. The chloride diffusion coefficient is an important input in service-life models for reinforced concrete."
