ABSTRACT:
Dry castable concrete compositions having improved strength and resistance to aggressive chemicals are provided. The compositions comprise water, hydraulic cement, fine and coarse aggregate, and condensed silica fume, wherein the weight ratio of condensed silica fume to hydraulic cement is about 0.10 to 0.25, the water to cement weight ratio is about 0.18 to 0.33, and the mix has a slump of about 1/2 inch or less. Also provided is a method of preparing the dry castable compositions using aqueous condensed silica fume slurries and a method of dry casting the compositions.
