Expansive Cement Concretes for Naval Construction.

Abstract

Expansion and subsequent shrinkage characteristics of shrinkage-compensating conrete were determined in mesh-reinforced prisms. The prisms were cured in fog for 14 days and then subjected to drying in either 25%, 50%, or 75% relative humidity (all at 73F). The concretes were made with four different aggregate types: (1) moderate quality river aggregate, (2) moderate quality limestone aggregate, (3) light-weight coarse aggregate and river sand, and (4) lightweight coarse and fine aggregates. Maximum aggregate size was 3/8 inch. The effects of the following variables on expansion and shrinkage were determined: amount of cement, amount of reinforcement, prism thickness, and relative humidity of shrinkage environment. Design recommendations are made for use of shrinkage-compensating expansive concretes in various climatic areas. (Author)
