Technical Summary: Calcium hydroxide is used as a high pH activator of sodium persufate. Calcium hydroxide is normally delivered in 50 pound or 1,000 pound bags. When added to soil or groundwater, calcium hydroxide will cause the pH of the surrounding treatment area to increase to over 10. 5 pH units.

I. INTRODUCTION II. EXPERIMENTAL HE Portland cement (C.E.M II) with pozzolanic admixture (slag) is low in C3S (tricalcium silicate), low in C3A (tricalcium aluminate) and low heat of hydration and high long term strength [1]. Hydrated lime (calcium hydroxide) or quicklime (calcium oxide) is commonly used in building construction.

Deterioration in these cements significantly exceeds that observed in plain and fly-ash-(FA-) blended cements. XRD and SEM analyses indicate that the greater deterioration in BFS- and SF-blended cements may be attributable to the depletion of the hydrated calcium hydroxide as a result of pozzolanic reaction.
