Coarse Aggregates: Types, Properites & Applications
1.Size of Coarse Aggregates: The size of the coarse aggregate depends on the use of the concrete is to be poured. For large-scale concreting operations without complex reinforcement, large aggregates of size 80 mm, 40 mm, 20 mm are used. For the simple construction of residential or other buildings, 20 mm is the maximum size will be used.

Shear Behavior of Reinforced Post-Filling Coarse Aggregate Concrete
Different from the traditional concrete mixing procedure, the innovative post-filling coarse aggregate concrete (PFCC) reduces the cost of pumping concrete by increasing the coarse aggregate content and reducing the usage of cement. Previous studies have shown that PFCC enhances the compressive strength, elastic modulus, and flexural strength of concrete. In this paper, the shear behavior of

Coarse Aggregates
Aggregates are processed to segregated coarse and fine aggregates, properly cleaned, and removed from other materials to give desired strength. Some aggregators are crushed, while some are screened and washed. The proper coarse aggregates processing will furnish cleanliness, sanitation to prevent contamination and maintained to upgrade the quality.

Specific Gravity of Coarse Aggregates: Its Importance & Test Procedure
Coarse aggregate occupies 70% to 80% of the volume of concrete. Aggregates are the material that the cement paste coats and binds together. The quality of aggregates imposes a significant impact on the properties of concrete like workability, strength, weight, durability etc.

Particle shape analysis of coarse aggregate using digital image processing
Abstract. The particle shape characteristics of the coarse aggregate used can significantly affect the workability, strength, and durability of the concrete produced. However, traditionally, particle shape measurements have to be done in a manual way that is both cumbersome and time-consuming. Herein, digital image processing (DIP) techniques
