A Detailed Guide on Grading of Aggregates.

20191120&ensp·&enspGrading of Aggregates. Grading of aggregates is determining the average grain size of the aggregates before they are used in construction. This is applied to both coarse and fine aggregates.The aggregate sample is sieved through a set of sieves and weights retained on each sieve in percentage terms are summed up.

What is the size of coarse aggregate used in concrete? Quora. Generally the size of coarse aggregate used is mm. If we use the proportional mix of different sizes small to large (> mm to 20/25 mm), this make the concrete structure compact by align themselves in voids depending upon their size and compact mass will be formed with increased strength.

Influence of coarse aggregate on the permeation

To obtain a range of coarse aggregate grading the proportion of 10 and 20 mm aggregate was varied. For the aggregate size effect, 10 and 20 mm single size aggregates were used. A constant water–cement ratio of 0.6 and aggregate–cement ratio of 6 was used in all the cases.

Step 4: The mix proportion of table 20.52 is based on the grading of aggregate shown in table 20.54. Step 5: Absolute density of materials is taken as given in table 20

Aggregates: Meaning and Classifiion Materials

20191023&ensp·&enspThus looking to these limitations and Bloem experimental results, the maximum size of aggregate for structural concrete should be limited to 25 mm preferably 20 mm. However for mass concrete aggregate sizes upto 150 mm can be used. However the decision would also be influenced by the cost and availability of different sizes of fractions.
