Impressive and unique properties and advantages have been obtained from a new concrete variant called dry-cast concrete, which has been developed by Gabriel-Wills Associates after 4 years of intensive research and testing, it differs from conventional concrete primarily in that water addition is accomplished by one of several infusion techniques after the mixture of aggregates and cement is placed in the mold, compacted and finished. Wet troweling is unnecessary, and special architectural effects and finishes can be worked into the dry material at little cost by means of hand tools, shaped screeds or rollers having patterned surfaces. The resulting concrete is virtually free of air bubbles and honeycombing, and the surfaces are characterized by exceptional form definition. Other significant advantages over conventional wet-mixed concrete are higher strengths, lower shrinkages, lower water permeabilities, reduced over-all concrete construction costs, more rapid curing rates, and reduced hydrostatic pressures.
