Abstract:

Through the authors' extensive research and development in the key issues of concrete technology and through their wide practical applications from prior to 1979 to the present time, they have recognized the importance of compatible gradation of aggregates and have evolved an optimum void-filling method of concrete proportioning to ensure full consolidation. The methods is based on four mutually dependent principles as follows: Compatibility between the grading of the coarse and fine aggregates is an essential factor in accurately controlling the total void content per unit volume of the combined aggregates; by applying the principle of gradation compatibility, engineering quality concretes can be readily designed from sound aggregates although full information may be lacking on some other characteristics of these materials; the compatible gradation of the aggregates and their optimum void-filling proportioning will lead to the formation of a plastic concrete that may be fully compacted even at large aggregate-cement ratios; and it is this concrete of largest aggregate-cement ratio with consistently minimum specific surface that will ensure the greatest economy and still retain compactible workability.
