WHAT IS THE GRADING LIMITS OF ALL IN AGGREGATE ...

The proper grading of an aggregate produces dense concrete and needs less quantity of fine aggregate and cement waste, therefore, it is essential that coarse and fine aggregates be well graded to produce quality concrete. Grading limits and maximum aggregate size are specified because these properties affect the amount of aggregate used as well ...

AGGREGATE GRADING AND THE INTERNAL STRUCTURE OF …

You will understand how grading of aggregates influences the bondage in concrete from the above picture. In well-graded concrete, two or more different aggregate sizes are used to influence the good bondage. In poorly graded concrete, single size aggregates are used in concrete. So cement paste can't induce good bondage between the material.
