It has long been recognized that no aggregate is completely inert in the environment of portland cement paste. This environment is always at least as alkaline as a saturated solution of calcium hydroxide and may for certain sources of cement exceed this alkalinity . We only need to consider those reactions which take place at a rate sufficient to affect the concrete during its normal life span. Carbonate aggregate reactions may be beneficial, innocuous, or deleterious.
