Changes in concrete and construction sometimes come at a glacial pace. But such changes also tend to be significant. One such change occurred at the semi-annual ASTM meeting in June. After 8 years of development and more than 20 years of existing as a part of another standard specification, a new document was created: ASTM C 1602/C 1602M-04, “Standard Specification for Mixing Water Used in the Production of Hydraulic Cement Concrete.”
The use of HVFA is not without reaction from the construction community. Yes, it can achieve performance equal to regular concrete and can do so at a comparable price. But, depending on the application, the owner must be willing to accept changes in scheduling, cost, or both.
