Additional info for Improving Concrete Quality

Example text

It is important that the concrete producer and the cement manufacturer work as a team as it is in the best interest of both that concrete of good quality with low variability and reduced low-­strength problems is made and placed. A good understanding of cement strength variations through effective use of ASTM C917 is essential in this regard. 3 Variation in Concrete Strength Due to Water and Air Content Variation This chapter discusses concrete strength variability due to variations in mixing water and air contents.

Moisture content, LOI, RD, and color were found to have no correlation with SAI for any of the fly ashes.

Do not ignore measuring coarse aggregate moisture content. If probes are not used, use a hot plate or a microwave oven. Measure aggregate moisture and update batch computers at least three times a week. Adjust added water in all loads to account for changes in aggregate moisture content. Stockpile aggregates and load aggregates into the plant to minimize variations. All of the above are NRMCA plant certification requirements. Establish company policy and equipment for slump rack water adjustment.
