LIGHT-WEIGHT calcium silicate hydrate (unit weight about 70 lb./ft.3) is made by curing cast mixtures of hydrated lime and silica for a number of hours in saturated steam at high temperatures. In previous work by Taylor and Moorehead1, it was shown that the maximum compressive strength for cast specimens depends on the lime–silica ratio and the specific surface area of silica flour used. A maximum compressive strength of 3,850 lb./in.2at one day was achieved at a unit weight of 64 lb./ft.3(strength/weight ratio 60) for specimens cured for 10 h in saturated steam at 186° C. |
