Abstract:
At the very beginning the importance of the aggregate in the make-up of concrete was appreciated, and the necessity for research in determining the laws for grading of aggregates, and also for determining the nature of organic matter, which experience has shown to be deleterious to concrete when occurring in bank sands. These two features, grading and impurities, have become more and more the prime factors in dealing with materials for concrete.
