No More Low-Alkali Cement? Why?! The Virginia Ready ...

This was the basis for the adoption of the maximum alkali limit of 0.60% (expressed as Na 2 Oeq) to designate “low alkali” portland cement in ASTM C150 in 1961 as a means to avoid the potential for ASR. However a limit on alkalies of the portland cement alone did not address the alkali content in concrete which is a function of the cement ...
