Influence of Microfine Aggregate Characteristics on

However, before this can be done, the positive and negative effects of microfine aggregates on concrete performance must be fully investigated. Previous research has indicated that there is not a strong correlation between standard aggregate characterization tests and concrete performance when microfines are present.

Influence of Microfine Aggregate Characteristics on

Influence of Microfine Aggregate Characteristics on Concrete Performance. ASTM C 33 limits the amount of aggregate smaller than 75 variance of m (No. 200 sieve) to be used in concrete. There is considerable interest in altering ASTM C 33 to allow a higher percentage of these microfine aggregates, particularly in the case of manufactured aggregates.

The Effects of Aggregates Characteristics on the

Aggregate shape, texture, and grading have a significant effect on the performance of fresh concrete. Aggregate blends with well-shaped, rounded, and smooth particles require less paste for a given slump than blends with flat, elongated, angular, and rough particles. At the same time, uniform gradings with proper amounts of each size
