The grading of aggregate influences the mix proportions for a specified workability and water-cement ratio. Coarser the grading leaner will be mix which can be used. Very lean mix is not desirable since it does not contain enough finer material to make the concrete cohesive.
The type of aggregate influences strongly the aggregate-cement ratio for the desired workability and stipulated water cement ratio. An important feature of a satisfactory aggregate is the uniformity of the grading which can be achieved by mixing different size fractions.

What is the effect of grading of aggregate on workability?
Grading of Aggregates enhances workability of concrete.
What is mean by good grading?
The word "grading" refers to the diversity in size of the aggregates. Aggregates that have "good grading" or are "well graded" have the same % of each size stone. The goal is to get the maximum aggregate packing density within a mix that still allows the cement to bond to the aggregates and cure properly, since its the aggregates that give concrete its high compressive strength.
What type of contractors offer grading services?
If no specialized grading contractors are available in your area, most landscape contractors offer grading services as well as many contractors who do excavation work. Drainage contractors will also often offer grading services.
What two experiments are used for aggregate degradation tests other than the aggregate impact value test?

Does sizes of aggregates affect the compressive strength of concrete?
Larger the size of aggregate will decrease strength of the concrete because surface area of this aggregate is low.Lesser the size of the aggregate will lead to increase the strength of the concrete.Well graded aggregate have all size of particles hence particle interferance is neglected,thus strength of concrete is more.
What is the effect of grading of aggregate on workability?
Grading of Aggregates enhances workability of concrete.
What mean by nominal size of aggregate?
Nominal size is the size of the largest aggregate in a grading.
What is Significance of fineness modulus?
Optimum for grading of aggregates and for surface texture of constructions.

What factors affect the workability of a concrete mix?
1),water content 2),mix praportions 3),size of aggregates 4),shape of aggregate 5),surface texture 6),grading of aggregates 7),use of admixture
What will happen when Aggregate demand and aggregate supply decrease?
When aggregate demand and aggregate supply both decrease, the result is no change to price. As price increases, aggregate demand decreases, and aggregate supply increases.
