After gelification, the gel is left undisturbed in the solvent for a long period of time (at least 48 hours) because the silica backbone of the gel still contains a significant number of
(portland cement, blended cement, fly ash, slag, silica fume, and natural pozzolans). The water-cementitious material ratio selected for mix design must be the lowest value required to meet anticipated exposure conditions. Tables 9-1 and 9-2 show requirements for various expo-sure conditions. When durability does not control, the water-cementi-

MATERIAL SAFETY DATA SHEET (Note 1) : Concentration of crystalline silica in a series of lime products will vary from source to source.It was not detected on some samples (< 0.1% w/w). Therefore two ranges are being disclosed. (Note 2) : ACGIH TLV Version 1973 has been adopted by the Mine Safety Health Administration (MSHA) as the regulatory Exposure Standard.
